The most important stories for you to know today
  • Misinformation rampant as fires ravage LA

    Topline:

    The thing with social media platforms is misinformation can spread as fast as the fires currently burning across the L.A. region. Hot off the announcement that Meta is doing away with fact checkers, social media has been ablaze with conspiracy theories and AI generated images and videos.

    Why does misinformation spread during a tragedy: Kristina Lerman, a research professor at USC’s Viterbi School of Engineering who specializes in misinformation, AI and how people communicate in digital spaces, said during times of crises  everybody's talking about the same thing so it gives opportunities for people to push their misinformation.

    Consequences: Cailin O'Connor, a professor at the University of California, Irvine, said sometimes when misinformation spreads, people can act on them and this could have consequences during an emergency situation.

    The thing with social media platforms is misinformation can spread as fast as the fires currently burning across the L.A. region. Hot off the announcement that Meta is doing away with fact checkers, social media has been ablaze with conspiracy theories and AI generated images and videos.

    The Department of Homeland Security says scammers take advantage of disasters and emergency situations “to further an ulterior agenda” by playing on people’s emotions and using trending algorithms for “hijacking conversations and financial scams.”

    Kristina Lerman, a research professor at USC’s Viterbi School of Engineering who specializes in misinformation, AI and how people communicate in digital spaces, said during times of crises  everybody's talking about the same thing so it gives opportunities for people to push their misinformation.

    “They use these opportunities, times of crisis, to push their agendas through propaganda,” she said. “They would take one grain of truth, and then they would twist it to fit the narrative, to promote their own specific narrative that they want to push.”

    Cailin O'Connor, a professor at the University of California, Irvine, said sometimes when misinformation spreads, people can act on it, which could have consequences during an emergency situation.

    " There's also kind of emotional impacts where sometimes people are upset or scared about things that they don't need to be because of misinformation spreading about something that's so scary and serious," she said.

    LAist sorted through the fact and fiction for you regarding some of the misinformation that has cropped up recently:

    • Should you book a ticket to L.A. to aid in clean up?

    No, there is a false post making the rounds on Facebook asking people to come to California to aid in the cleanup of areas affected by the fires. CalFire officials say this is false and “there is no such opportunity available.”

    • Are fire crews from South Africa aiding in the firefighting efforts?

    No. A video circulating on social media shows firefighters from South Africa landing at a Canadian airport while supposedly enroute to Los Angeles. The video was from 2023 when South African crews aided in firefights in Mexico.

    • Were Oregon firefighters turned away because their equipment did not pass emission tests?

    No. They were not turned away and their equipment did pass safety checks. Oregon firefighters joined in the L.A. firefight Friday morning.  ”The L.A. County Fire Department has never turned down any offers for mutual aid assistance and resources,” L.A. County Fire Chief Anthony Marrone said at a news conference Monday.

    • Did fire crews actually use handbags to put out the fire?

    On the contrary, those bags in the videos circulating online are canvas bags, an LAFD spokesperson told CBS News. Canvas bags are a common tool used by first responders to put out smaller flames — an easier response than pulling out a hose.

    • Did the Hollywood sign burn? Was a neighborhood mosque the only structure left standing?

    No and no. The image of the Hollywood sign on fire is AI generated and the mosque in question is in Indonesia. Want to fact check content forwarded to you? You can use Google Reverse Image Search.

    • Is Gov. Gavin Newsom going to work with property developers to rebuild Pacific Palisades into apartments instead of single family homes?

    No, Newsom took to X to refute those claims. And changes to zoning fall under the purview of city governments, not the state.

    • Why didn’t Newsom sign the "water restoration" declaration?

    There is no water restoration declaration, despite what President-elect Donald Trump said. Read more here.

    • Why did the water hydrants in Pacific Palisades run dry?

    They didn’t. Pressure in those water hydrants was reduced as demand for water – four times than normal – increased. My colleague Kevin Tidmarsh has a great explainer here.

    • More brush clearance could have helped prevent the Palisades Fire, why wasn’t it done? 

    Even if the excess vegetation was cleared, there was no stopping the powerful winds that fueled the spread of the wildfires. The winds could cast embers more than a mile away, making containing the spread impossible, my colleague Jacob Margolis writes.

    • Can I donate to the L.A. County Fire Department via links I found online?

    No, the L.A. County Fire Department is currently not accepting online donations as they do not have a system in place to accept them.  "We have staff working on a process to accept donations over the internet for our L.A. County Fire Department," said L.A. County Fire Chief Anthony Marrone. "I ask that those wanting to donate hold off until we have a process established that will guarantee the funds benefit our personnel."

    • I am seeing reports online about how the L.A. Fire Department prioritized DEI efforts in the last few years and that's why the wildfires caused so much destruction. Is this true?

    L.A. Fire Department is headed by a gay woman, Kristin Crowley. As our friends at NPR write, partisan politics during a crisis is used to drive engagement online.

    "The story is something like this: We as a society used to hire on the basis of competence and meritocracy. But that system has been hijacked by powerful minorities," Ian Haney López, a law professor at the University of California, Berkeley and the author "Dog Whistle Politics" told NPR.

    • How can I get a permit for expedited reentry into Malibu?

    You can't get one because they don't exist. The city of Malibu said people are not currently allowed into evacuation zones, neither are private contractors. If people need to check on a pet or obtain medication, they can call the city at (310) 456-2489.

    • I have heard the billionaire owners of The Wonderful Company, Stewart and Lynda Resnick own most of the water in California. Is this true?

    Stephanie Pincetl, director of the California Center for Sustainable Communities at UCLA, told NPR that they do use a lot of the state's water, but it is not "distinct and not germane to the problem" of battling wildfires.

    • Are we running out of water to fight the wildfires?

    We are not. Local reservoirs have enough water to aid firefights. " There's way more water in local storage than you could ever fight a fire with," Marty Adams, former general manager and chief engineer of the Los Angeles Department of Water and Power, told NPR.

    • Did mansions belonging to Ukrainian military officers burn down in the fire?

    No, that was misinformation pushed by pro-Kremlin accounts. "It is the latest in a long string of assertions by Russian officials, media, and the pro-Kremlin online ecosystem that Ukrainian officials are corrupt and use foreign aid money to enrich themselves." Léa Ronzaud, a senior investigator at research firm Graphika, told NPR.

    • California has stringent environmental policies. Did those cause the wildfires?

    No, this is a claim by people like Elon Musk doing the rounds on social media. Experts from UCLA's Law School Emmett Institute say the regulations help rather than hurt California. The L.A. Municipal Code requires homeowners to clear brush that could pose fire risk from near their property. The state also passed a law in 2020 requiring homeowners to create a 5-foot fire resistant buffer zone around their property. That law hasn't been formally enforced as some homeowners are resistant to the change because they don't find it aesthetically pleasing.

    How to be a fact checker

    Lerman and O'Connor shared some tips that people can use to sift through all the information:

    • Take a moment to verify. Turn to other people in your social circles, the media or government officials to verify claims. For example, when the false alarm evacuation texts were sent out, a call to the local police station confirmed that it was indeed false. 
    • Check your source. If the message has a political bias, ask whose agenda it could be serving. “ Anything that's linked to the blame game right now, like blaming somebody as being responsible for it, that's a sure sign that's actually being used for propaganda purposes and not to convey relevant information,” Lerman said.  Some of the best information comes from those who have vast experience and background on topics. “If it’s an online influencer, like a fashion influencer or celebrity or even a politician from outside of the state who really is not addressing the wildfires directly, then be skeptical about the information they are promoting because they could have some hidden agenda behind it.”
    • Check if an image is AI generated — a tall tale sign is misplaced text or inaccuracies. For example, the viral photo of the Hollywood sign on fire had an extra L in “Hollywood.”
    • Slow down. O'Connor said take a moment to pause before sharing information. Sometimes just stopping to think through what you are about to share can help distinguish whether it is false or not.

    This story will be updated as more misinformation is spotted.

  • What he's meant for the World Cup
    A man in a dark suit and tie sits at a desk with a podium mic and a blue, red, white and green soccer ball sitting in front of him. He's arching eyebrows and raising his hand up.
    Gianni Infantino, President of FIFA, speaks to the media during a FIFA World Cup 2026 Opening Press Conference at Mexico City Stadium.

    The topline:

    Gianni Infantino, the president of FIFA, is instrumental in how fans in Los Angeles and beyond are experiencing soccer, from ticket prices to the flow of the matches. Here's what to know about his tenure as president and how he's responded to controversies.

    His prior experience: Before leading the international governing body for professional soccer, he had worked with the Union of European Football Associations (UEFA), most notably as the secretary general.

    Entertainment-related reforms: In 2023, he helped finalize the number of teams in this year’s World Cup, from 32 to 48. The number of total games played also increased to 104, up from 64 in the 2022 World Cup.

    Read more... to better understand how he entered the presidency following a massive corruption scandal.

    The World Cup has officially taken over Los Angeles, and not without controversy.

    Fans have voiced frustration over ticket pricing and questions linger over whether the Iranian football team should be playing in the tournament.

    Listen: Should Iran be playing at SoFi? Listeners weigh in as tentative US-Iran deal is announced

    The man at the center of these decisions and how fans in Southern California are experiencing the World Cup is FIFA President Gianni Infantino.

    Here's why he's the most influential voice in soccer right now.

    How he got elected

    The election of Infantino followed one of the worst corruption scandals in sports history. In 2015, the U.S. Department of Justice indicted more than a dozen FIFA officials and executives on charges of bribery, money laundering and wire fraud.

    Swiss authorities launched an additional investigation, which led to former FIFA President Sepp Blatter's resignation. He had held the position since 1998.

    Following the corruption scandal, Congress passed a reform package, but criticism remains over lack of follow through.

    Part of Infantino's success has been built on his ability to boost revenue for FIFA over the years.

    Ticket pricing, human rights and other critiques

    Getting in on the World Cup games here in L.A. has likely been... expensive.

    And that's been one of the biggest critiques of Infantino as matches approached and FIFA announced ticket pricing would adjust based on demand. Infantino has defended the pricing method, comparing it to other major American sporting events.

    Coaches, players and fans are also split on FIFA's decision to add three-minute mandated hydration breaks to matches, according to Reuters.

    Infantino has also been criticized for downplaying concerns over human rights. For example, the Guardian reported in 2021 that more than 6,500 migrant workers died in Qatar during the 10-year lead up to it hosting the World Cup in 2022.

    Oliver Kay, The Athletic's senior soccer writer, said during a conversation on LAist 89.3's AirTalk that Infantino's legacy is complicated and leaves true soccer fans with questions.

    " How many of these decisions are being made for the good of the game, and how many of them are being made for whichever world leaders Infantino is cozying up to at that time?" Kay said.

  • A historian says it wasn't always like this
    public_restroom.jpg
    Public restrooms are hard to access in a place like Southern California.

    Topline: 

    Los Angeles, like other major cities in the U.S., doesn’t have the most robust stock of accessible restrooms and although that’s nothing new, it wasn’t always like this.

    Why it matters: With the World Cup fully underway and the LA28 Olympics on the horizon, bathroom access is bound to cause a stir for fans visiting from all around the world.

    History: Temple University professor Bryant Simon, who is the author of the forthcoming book For Customers Only: Public Bathrooms and the Making of American Inequality, says cities used to compete with each other to build the most lavish public bathrooms, including L.A.

    “In 1911 in L.A., the mayor held a ribbon-cutting ceremony and bragged about how ornate the bathroom was,” he said.

    Now what? Read more to learn when things shifted and what Simon thinks is necessary to improve access.

    Why are public bathrooms so hard to find?

    With the World Cup fully underway and the LA28 Olympics on the horizon, bathroom access is bound to cause a stir for fans visiting from all around the world.

    Los Angeles, like other major cities in the U.S., doesn’t have the most robust stock of accessible restrooms, and although that’s nothing new, it wasn’t always like this.

    LA’s opulent toilets

    As it turns out, L.A. was one of the epicenters of the early 20th century bathroom boom (no pun intended).

    Temple University professor Bryant Simon, who is the author of the forthcoming book For Customers Only: Public Bathrooms and the Making of American Inequality, joined AirTalk, LAist’s daily news program, to talk about the history of public bathrooms and how we got to where we are today.

    “Cities would compete with each other to build the most lavish public bathrooms,” Simon said. “In 1911 in L.A., the mayor held a ribbon-cutting ceremony and bragged about how ornate the bathroom was.”

    When things started to go down the toilet

    The goal was simple: encourage the public to feel safe and confident leaving their homes by creating convenient spaces for people to relieve themselves.

    Instead, these public bathrooms attracted a different type of crowd.

    “Drinkers and smokers, people using drugs and most ominously for city leaders, people seeking sex,” Simon said, adding that almost immediately authorities throughout Southern California started arresting men who were seeking sex with other men.

    “We have pay toilets now. It's called Starbucks."
    — Bryant Simon, Temple University professor and author

    So, cities felt they had no choice but to close public bathrooms all together.

    “Jim Crow laws fall down and cities closed public bathrooms,” Simon added.

    Simon said this trend continued into the 1980s, with stricter policies around homelessness.

    Today, you can see from this map how many bathrooms there are in the city and county, which has put some LAist listeners in a tough spot and on both sides of the issue.

    “ I was skateboarding in downtown Los Angeles. It was a dire situation. I saw a construction site that was nearby, and they had a porta potty, so I had to hop this fence. It was probably 8 or 9 feet tall.” –Derek in Rancho Cucamonga 

    “There wasn't anything on this particular stretch of [the 91], and some of the places that I went to were actually closed. Things just got so terrible, I had to find the most remote neighborhood, get in the back of my SUV and urinate in a cup.”  –Susan in Huntington Beach 

    “I've been someone who urgently needed a public restroom, and I run hospitality businesses. We're generally pretty supportive of it, but … we've had people cause massive damage or even had to call the police because people wouldn't leave.” – Steve in Long Beach

    Where do we go from here?

    Similar to European models — big U.S. cities previously instituted for-pay toilets, but by 1974, they were outlawed after a gender equity campaign argued they discriminated against women who were forced to pay, while men could use urinals for free.

    “ We have pay toilets now. It's called Starbucks,” Simon said.

    Starbucks is trying to stem the loss of customers by simplifying its menu, reintroducing ceramic mugs and making other changes to be more like a local coffee house.

    Simon added that when private companies are essentially operating public toilets, they tend to become inherently unfair because the focus is on profits.

    He says if public bathrooms are to come back at scale, they need to be maintained, including proper cleaning — and this likely means human attendants are involved.

    “Public bathrooms have been closed over decades in order to keep other people away to the point that now we're all in the same boat of having no public bathrooms,” Simon said.

  • CA requests could be costlier, wait times longer
    Assemblymember Blanca Pacheco, a woman with medium skin tone, wearing a violet suit, holds a packet of papers.
    Assemblymember Blanca Pacheco in the Assembly in Sacramento on March 13, 2025.

    Topline:

    In March, Assemblymember Blanca Pacheco introduced a measure that would have made it more expensive for Californians to obtain government records. Amid opposition and public access concerns, the Downey Democrat diluted her proposal to simply give governments more time to respond to records requests, a change that allowed the measure to sail through the Assembly in May. Now, she’s brought the controversial elements back — and they are even more restrictive than before, drawing fierce opposition from transparency advocates.

    About the new version of her bill: Assembly Bill 1821 would allow government agencies to delay responding to certain requests and to charge at least $88 an hour to search for and review the records they deem are for “commercial use.” Government agencies could also take requests to court if they believe someone is asking for the records for a malicious reason. Pacheco told CalMatters her measure aims to prevent frivolous records requests from inundating local governments, especially requests generated by artificial intelligence.

    The opposition: First Amendment advocates say state law already allows agencies to decline frivolous records requests by arguing that they are “unduly burdensome.” Even when requests are legitimate, agencies routinely delay fulfilling them or withhold records for months or years, drawing legal challenges. Pacheco’s measure would create barriers that would chill the public from filing requests, effectively gutting the state’s open records act and violating the spirit of Californians’ constitutional right to government information, transparency advocates argue. Critics also slammed the measure for empowering agencies to decide how quickly they need to respond to requests based on how people file them.


    In March, Assemblymember Blanca Pacheco introduced a measure that would have made it more expensive for Californians to obtain government records.

    Amid opposition from transparency advocates and public access concerns from her own Assembly colleagues, though, the Downey Democrat diluted her proposal to simply give governments more time to respond to records requests, a change that allowed the measure to sail through the Assembly in May.

    Now, she’s brought the controversial elements back — and they are even more restrictive than before, drawing fierce opposition from transparency advocates.

    The latest version of her proposal, Assembly Bill 1821, would allow government agencies to delay responding to certain requests and to charge at least $88 an hour to search for and review the records they deem are for “commercial use.”

    Government agencies could also take requests to court if they believe someone is asking for the records for a malicious reason.

    Pacheco told CalMatters her measure aims to prevent frivolous records requests from inundating local governments, especially requests generated by artificial intelligence.

    For years, local agencies have argued that fulfilling extensive records requests burdens public workers and allows bad actors to overwhelm governments. In 2023, someone requested Bay Area city officials’ emails to train an AI service they wanted to sell to local governments, said Donald Larkin, an attorney representing the League of California Cities, which supports the legislation.

    “Transparency is important to me,” Pacheco said in an interview. “We just want it to run efficiently, and these are just minor amendments or minor tweaks to the Public Records Act.”

    But First Amendment advocates say state law already allows agencies to decline frivolous records requests by arguing that they are “unduly burdensome.” Even when requests are legitimate, agencies routinely delay fulfilling them or withhold records for months or years, drawing legal challenges.

    Pacheco’s measure would create barriers that would chill the public from filing requests, effectively gutting the state’s open records act and violating the spirit of Californians’ constitutional right to government information, transparency advocates argue.

    “The only way that there’s any government accountability is that people know what the government is doing,” said David Snyder, a former journalist and now the executive director of the First Amendment Coalition.

    “This looks a lot like an effort to evade accountability.”

    The proposed changes would “make California stand out as the most secretive state in the country,” said David Cuillier, a University of Florida journalism professor who sits on the federal Freedom of Information Act advisory committee.

    The whiplash of amendments angered many transparency advocates, who criticized Pacheco for overhauling her proposal only after it was approved by the Assembly.

    The move, prevalent in the Legislature, “often leads to badly written bills with dangerous side effects and AB 1821 now fits squarely into that category,” said Tracy Rosenberg, advocacy director at local watchdog group Oakland Privacy, who called the proposal “a virtual horror show of governmental non-transparency.”

    Authority to sue for ‘malicious’ requests

    While many local governments across the nation have sued — and largely lost — over what they consider “vexatious” requests, California would be the first state to explicitly allow agencies to sue for “malicious intent.” Requesters the court deems malicious would have to pay $88 an hour to obtain records.

    Public agencies already use the courts to target requests they don’t like, and rubber-stamping that authority by writing it into law would embolden them to deny more requests, First Amendment advocates say.

    “It would be easily weaponized by agencies seeking to thwart transparency and accountability, as has already happened elsewhere in the country,” Snyder said.

    The threat of a lawsuit alone would “chill requesters from submitting public requests,” said Shaila Nathu, a senior attorney with ACLU of Northern California, which also opposes the bill.

    Pacheco dismissed the concerns, stating that she doubts that cities would sue very often because it’d require them to go to court just to recover a limited amount of fees. But the provision would offer a tool just in case, she said.

    “Hopefully this will curb the bad actors,” she said. “I don’t anticipate that this would slow down legitimate requests.”

    ‘Outrageous’ fees risk chilling public engagement

    Advocates also criticized Pacheco’s fee proposal, arguing it would discriminate against requesters based on their use for the records. State law bars agencies from limiting access to public records based on purpose.

    The measure would allow agencies to charge more for requests they deem to further someone’s “commercial, trade, or profit interests.” It would exempt just a small group of people, such as academics, journalists and government agencies. Under current law, agencies can only charge for making copies of the records, usually at between 10 to 50 cents a page.

    For the rest of the public, agencies could ask them to submit information “promptly” to prove their intent and automatically treat those who don’t as commercial requesters. The bill includes no standard for what is “prompt.”

    “It’s so fact-specific that it’s kind of hard to say what’s reasonable, what’s prompt,” Pacheco said. “Most people will reply if a city asks, and then the city can then obtain the records for the individual.”

    Assemblymember Blanca Pacheco during a floor session at the state Capitol in Sacramento on March 23, 2026. Photo by Fred Greaves for CalMatters In an email, Pacheco spokesperson Alina Evans told CalMatters that the assemblymember wants to prevent taxpayers from subsidizing “the cost of building or improving a private company’s commercial product.” But, she said, Pacheco will amend the measure to prevent forcing every requester to justify their request.

    Snyder said that language would give governments broad authority to play favorites — “to see why it is somebody’s requesting records and then to potentially make decisions based on that.”

    Those deemed commercial would have to pay $22 an hour in “administrative fees” and $66 an hour in “professional fees” for the search, review and redaction of the records, although the California Supreme Court already ruled in 2020 that such charges threaten Californians’ right to access.

    That hourly rate would be “outrageous” and could easily become so burdensome that low-income Californians stop filing requests altogether, Cuillier warned.

    Critics also slammed the measure for empowering agencies to decide how quickly they need to respond to requests based on how people file them.

    Under current law, government agencies must respond to a request within 10 calendar days and extend the deadline for providing the records by no more than 14 calendar days. The law does not mandate a specific format for submission, although many local and state agencies allow requests through an online portal.

    Pacheco’s bill would extend the timeline to 10 and 14 business days respectively, but only if the requests are filed in person or by email during normal business hours.

    Those requesting records by fax, by mail or through an online portal would be at the agencies’ mercy.

    The initiative originated from one of Pacheco’s many trips sponsored by special interest groups last year, her spokesperson, Alina Evans, told CalMatters in March. Last year, Pacheco reported receiving more than $45,000 in sponsored travel — the most of any California lawmaker — including a study tour in Spain, a golf tournament in Pebble Beach and a conference in Maui. When asked Wednesday, however, Pacheco said she did not remember which one inspired her measure and said the idea came from multiple conversations with local governments.

    The latest amendment reflects talks Pacheco had with the League of California Cities, the California State Association of Counties, the city of Downey, municipal clerks and several lawmakers on the Assembly Judiciary Committee, which approved a much narrower version of her proposal, Evans said.

  • Air quality remains an issue day after fire
    A black and white SUV police car is parked in the middle of a street behind yellow police tape. Several red fire trucks are also parked in the street and thick black smoke is pictured in the distance.
    A fire at a Boyle Heights commercial building Wednesday prompted a shelter-in-place order for hours due to hazardous materials, including ammonia.

    Topline:

    A fire at a Boyle Heights commercial building Wednesday prompted a shelter-in-place order for hours due to hazardous materials, including ammonia. Residents are still expressing concerns over air quality. Here’s what we know.

    What materials were burned in the fire?: The fire broke out at Lineage, a logistics company that offers cold storage services, according to the company’s website. The fire spread across the building’s rooftop solar panels. The fire also reached an ammonia line, causing it to off-gas the chemical, and adjacent structures were evacuated to keep people from breathing it in. The ammonia is not toxic to individuals unless they have respiratory issues or come into direct contact with it, fire officials said. 

    Air quality after the fire: A particle pollution advisory was in effect until at least 12:30 p.m. Friday for an area including Boyle Heights, central LA and parts of Northeast LA. At a press conference Thursday morning, LAFD officials said air quality was being monitored in the area, adding that there was no public threat. However, residents in Boyle Heights reported concerns over smoke, ash and the lingering smell; the air remained acrid and smelled like plastic on Thursday morning.

    A fire at a Boyle Heights commercial building Wednesday prompted a shelter-in-place order for hours due to hazardous materials, including ammonia.

    The fire broke out at Lineage, a logistics company that offers cold storage services, according to the company’s website. 

    A shelter-in-place order was lifted at around 8:45 p.m. Wednesday, but the fire remained smoldering as of 11 a.m. Thursday, and firefighting efforts continued. 

    Residents are also still expressing concerns over air quality. Here’s what we know.

    What materials burned in the fire?

    The fire spread across the building’s rooftop solar panels, prompting firefighters to use helicopters to take on the flames and prevent further spread. 

    “Any sort of structure fire with [solar] panels burning, there’s going to be some sort of hazardous materials in the air,” LAFD firefighter Jennifer Middleton.

    The fire also reached an ammonia line, causing it to off-gas the chemical, and adjacent structures were evacuated to keep people from breathing it in.

    The ammonia is not toxic to individuals unless they have respiratory issues or come into direct contact with it, fire officials said. 

    What to know about smoke and air quality 

    A particle pollution advisory was in effect until at least 12:30 p.m. Friday for an area including Boyle Heights, central LA and parts of Northeast LA.

    At a press conference Thursday morning, LAFD officials said air quality was being monitored in the area, adding that there was no public threat.

    However, residents in Boyle Heights reported concerns over smoke, ash and the lingering smell; the air remained acrid and smelled like plastic on Thursday morning.

    Boyle Heights Beat reached out to the South Coast Air Quality Management District and the LA County Department of Public Health to ask about air quality levels and how officials determine whether there is a threat to public health. 

    “Preliminary results from the mobile monitoring showed particulate matter was generally near background levels, however, elevated particulate matter concentrations were observed for a few seconds at a time within the plume,” the AQMD said. “During those few seconds, increased levels of bromine and chlorine were also observed. Bromine and chlorine are typically found at trace levels during structural fires and the levels seen were below short-term health-based exposure thresholds. Concentrations below this level are not expected to cause adverse health effects. No significant levels of air toxic metals were seen.”

    As firefighting continues, people downwind may continue to notice poor air quality, the agency added. Smoke becomes cooler as firefighters gain control, causing it not to rise as dramatically into the air. 

    What should residents do

    The LA County Public Health Department issued guidance Wednesday on how residents can protect themselves. 

    • Officials recommend remaining indoors, keeping windows and doors closed, and limiting exposure to outdoor air if residents can see or smell smoke.
    • Residents with respiratory conditions should continue monitoring local air quality and exercise caution.
    • Run an air purifier if available, but avoid using air conditioners, which bring in outside air (you may qualify for a free one here)

    What symptoms to watch for

    Contact your doctor, go to urgent care or call 911 if you experience:

    • severe coughing
    • shortness of breath,
    • wheezing
    • chest pain,
    • palpitations
