The Brief

Gross black dust on your windowsill. Sickly yellow haze that obscures the mountains. Childhood memories of recess cancelled due to smog alerts.

You know the air here is dirty. Now learn why.

Once Upon A Time

The L.A. smog story goes a little like this: on July 8, 1943, a mysterious haze descended on the city.

"People were having car accidents," Chip Jacobs, co-author of Smogtown: The Lung-Burning History of Pollution in Los Angeles, told LAist. "Mothers were wondering why their kids' eyes were watering. Police officers were spinning loopy."

What was this strange haze? Was it a gas attack? Smoke from factories? From some distant fire?

To solve the mystery, local officials formed the nation's first air quality regulator, the Los Angeles County Air Pollution Control District. They began looking into the problem and quickly learned that there were a lot of sources of air pollution in greater L.A.: people burning trash in their backyards, oil refineries, smudge pots (which are small, smoky fires used by citrus growers to keep trees warm at night), and factories.

But soon, a Caltech scientist figured out that cars and gasoline were largely to blame for the eye-watering, lung-searing haze.

What Do Cars Have To Do With It?

Car exhaust has two main components: hydrocarbons, from the gasoline, and nitrogen oxides, which are formed inside hot, internal combustion engines. Both are harmful in and of themselves, but when they float into the sunny, Southern California air, the sunlight bakes them into a new chemical: ozone, also known as smog.

Once scientists figured out what caused smog, the crackdown began: in 1967, a new state air quality agency, the Air Resources Board, was formed. It enacted tailpipe emissions standards for cars. It required catalytic converters on new models, cleaner gasoline and, at the gas pump, those little rubber boots that trap fumes from the nozzle. In 1984, smog checks began statewide. Other industries had to clean up, too: oil refineries, cement plants, power plants. And as California cleaned up its air, other states and the federal government followed.

L.A. has the worst ozone, or smog, in the country, according to the American Lung Association's 2021 State of the Air Report.

Bad Now Vs. Bad Then

The air is a lot cleaner now. In 2020 , we had 157 days of unhealthy air, compared to well over 200 in the late 1980s. However, 2020 tracked the highest number of unhealthy air days since 1997, even with pandemic restrictions seeing a drop in auto travel. So when it's smoggy, it's not as smoggy as it used to be.

But Los Angeles still has the worst smog in the country, according to the American Lung Association's 2021 State of the Air report. (Again, scientists call smog "ozone." But they're the same thing).

Greater L.A. exceeded federal air quality standards for 157 days in 2020.

Part of the problem is that it's been hot, incredibly hot. And heat speeds up the process of ozone-formation. Experts are trying to figure out whether the spate of bad air is a new trend, reversing years of steady progress.

"Is this weather, or has this become climate?" said Atwood. "We're grappling with that question basically."

What Makes Our Smog So Special?

Three reasons.

• One, there are a lot of us, and we own a lot of cars. Angelenos own 0.54 vehicles per person, compared to 0.43 in New York City. Also, we have the busiest ports in the country, which means tens of thousands of heavy-duty diesel trucks are on our roads, and they are way dirtier than cars.
• Two, the mountains that ring the L.A. Basin trap that pollution as it gets pushed eastwards by sea breezes.
• And three, our climate. Nearly three out of four days in L.A. are sunny. And the L.A. Basin frequently experiences a weather pattern where a layer of warm air will sit on top of a layer of cooler air and prevent it from dispersing. That traps pollution closer to the ground. Think of it like putting a lid on a pot.

Where's The Dirtiest Air? Where's The Cleanest?

Because the wind blows smog east, towards the mountains, the air is worst there. So places like Redlands, San Bernardino and even the tiny, mountain community of Crestline have far worse air quality than coastal cities like Long Beach or Santa Monica.

But there's another factor to consider besides smog: the raw vehicle emissions that combine to make smog can also have localized health impacts. So if you live within 500 feet of a busy road or a freeway, you're in a pollution hot spot, because that's where vehicle emissions are the most concentrated.

In the very worst places to live, like near a freeway in San Bernardino, you will be exposed to both smog and raw vehicle emissions, said Ed Avol, the head of the Environmental Health Division at the USC Keck School of Medicine.

"It's sort of like a double whammy, so you get both the local impact of being near a roadway, and you also get the accrued accumulation of pollution that's become a regional issue," he said in an interview with KPCC/LAist in April.

What Will Breathing Dirty Air Do To Me?

When you breathe in dirty air, it triggers an inflammatory response in your body. And once that happens, a lot of bad things can happen. In the short term, air pollution can cause:

• Difficulty breathing and chest pain.
• Increased rates of asthma.
• Respiratory diseases like bronchitis and pneumonia.
• Lost school or work days.
• Doctor and hospital visits.
  

Over the long term, it's much worse. Kids who grow up breathing dirty air, whether it's from living near a freeway or in a smoggy area, or both, have weaker lungs that don't work as well.

"If they never get that maximum lung growth early in life, it looks like it's permanently lost," Avol said.

For older adults, air pollution can contribute to cognitive decline, memory loss and premature death. It can also exacerbate heart disease, diabetes, obesity and cause cancer. There's even research suggesting fetuses are harmed when their moms breathe dirty air.

"In a cynical, joking way, you could say we believe air pollution causes everything," Avol said.

How Can I Protect Myself And My Family From Bad Air?

One of the most common ways people are exposed to pollution is while driving. So when you're on the freeway, be sure to keep your windows rolled up and re-circulate the air, instead of drawing it in from the outside. Changing your air filter also helps. And new cars are more tightly sealed than older cars, keeping pollution out.

If you can, try to live at least 500 away from a freeway or busy road. If you can't, using HEPA air filters has been shown to significantly reduce indoor air pollution when the air outside is dirty. Clean that black dust, which is a combination of diesel soot and rubber dust from tire wear, off your window sills.

Outside of the home, try to walk or bike on less busy streets, to limit your exposure to vehicle exhaust. When waiting for the bus, stand back from the street corner, where pollution levels soar when vehicles accelerate from a stop. And don't exercise near busy roads during rush hour, especially in the morning, or when the air is especially bad.

You can also check the air quality every day. This South Coast Air Quality Management District map will give you a good overview of air in your area. You can also check the Purple Air network, which measures particulate matter (like soot, dust and wildfire smoke), or have a low-cost air monitor installed at your home or work.

What Do We Need To Do To Make The Air Actually Clean?

It all comes down to transportation. Cars and trucks make up nearly 90 percent of the smog-forming pollution in Southern California (not to mention they are also the largest emitters of greenhouse gases in the state), and it's because they run on gasoline and diesel.

Switching to fuels with zero tailpipe emissions, like electricity and hydrogen fuel-cells, will make a huge difference, says Will Barrett, the clean air advocacy director for the American Lung Association.

"We need to see more focus and urgency on the conversion of the heavy duty sector to zero emission technology," he said.

But heavy duty trucks have proven tricky, so far, to electrify, because they would require a massive battery to power them over long distances while carrying heavy loads. Also, truckers would need frequent, convenient charging stations, and that infrastructure doesn't exist yet.

California regulators, ever the clean-air optimists, are throwing cash at the program. The ports of L.A. and Long Beach, for example, have a goal of shifting their entire fleet of largely diesel trucks and equipment to zero emissions technology by 2035 -- at a cost of $14 billion. If they can figure it out, all of our lungs will benefit.

A federal judge has ordered Los Angeles to pay more than $1.8 million in attorneys’ fees and costs to the L.A. Alliance for Human Rights and other organizations that sued the city over what it deemed an inadequate response to the homelessness crisis.

The city is appealing the decision.

The details

L.A. Alliance is a group of business owners and residents who sued the city and county of Los Angeles in 2020 in an effort to push both governments to provide more shelter to unhoused people in the region.

The city of L.A. settled with the plaintiffs in 2022, and U.S. District Judge David O. Carter is overseeing the city’s progress in keeping up with the terms of that agreement. The judge found the city breached its agreement in multiple ways in a ruling last summer.

Specifically, the judge found that the city did not provide a plan for how it intends to create 12,915 shelter beds, as promised, by 2027. The court also found the city “flouted” its responsibilities by failing to provide accurate, comprehensive data when requested and did not provide evidence to support the numbers it was reporting, according to court documents.

In addition to $1.6 million in attorneys’ fees and $5,000 in costs to L.A. Alliance, Carter awarded about $200,000 in fees and $160 in costs to the Los Angeles Catholic Worker and Los Angeles Community Action Network.

The organizations are considered “intervenors” in the suit, representing people experiencing homelessness on Skid Row. Their attorneys include those from the Legal Aid Foundation of Los Angeles.

Why it matters

In his order, released Tuesday, Carter compared the recent award to the millions of taxpayer dollars city officials agreed to pay an outside law firm representing L.A. in the settlement.

Carter wrote in the order that the attorneys' fees and costs to L.A. Alliance and others “is reasonable, especially in light of the approximately $5.9 million that the City’s outside counsel is charging.”

LAist’s housing and homelessness coverage was cited several times in the order.

“It has fallen to plaintiff, intervenors, and journalists to point out the deficiencies in the city’s reporting,” Carter wrote, referring to data the city is required to report to the court as part of the settlement.

“Plaintiff and intervenors must be compensated for this,” he said.

The city’s response 

Attorneys representing the city filed a notice of appeal with the U.S. District Court in Los Angeles on Thursday.

L.A. City Attorney Hydee Feldstein-Soto’s office did not respond to LAist’s requests for comment by phone or email.

Shayla Myers, senior attorney with the Unhoused People's Justice Project at the Legal Aid Foundation of Los Angeles, told LAist the intervenors participated in the case without compensation “because it's incredibly important given what is at stake in these proceedings that unhoused folks have a voice.”

Matthew Umhofer, an attorney for L.A. Alliance, told LAist he’s thrilled the court is imposing accountability on the city, including sanctions for violating the settlement agreement. But Umhofer said he’s saddened that L.A. Alliance is going to have to keep fighting to hold the city to its promises.

“The obvious city strategy here is hire a big, good law firm to fight on absolutely every front in hopes that the plaintiffs, the intervenors or the court will ultimately give up trying to hold the city accountable,” he said.

What's next

The parties are scheduled to appear in federal court in downtown L.A. on Monday, when a hearing will resume to determine whether the judge will hold the city of Los Angeles in contempt of court.

Carter has said in documents that he’s concerned “the city has demonstrated a continuous pattern of delay” in meeting its obligations with court orders under the settlement and that the “delay continues to this day.”

Every January, the open-air downtown food fair reopens after its winter break and announces new additions to its carefully selected group of regular vendors.

This year’s new vendor class demonstrates the resilience of L.A.'s independent food scene, ranging from a Grammy-nominated producer's Persian-influenced pizza to Southern fried fish celebrating Black American culinary traditions, to an LAist 2025 Tournament of Cheeseburger heavyweight contender.

The reopening also marks the start of Smorgasburg LA's 10th anniversary year, and will feature 41 returning vendors, who've helped build the regular event into a fun, family-friendly opportunity to try new, often cutting-edge food you may not be familiar with.

Doors open from 10 a.m. to 4 p.m. at DTLA’s The Row, with free entry and free parking for the first two hours.

A new year

General manager Zach Brooks said this is his favorite time of year. "We add the new vendors at the beginning of the new year, everyone's excited."

Vendors apply through Smorgasburg's website, and the team meets with every applicant to taste their food before acceptance. Brooks said it's not a vetting process like "Shark Tank" but rather a matter of seeing if it's a good fit. Competition remains fierce, with many more applicants than available spots.

"I think it's just a testament to L.A. and the resilience of people who love this business and have a passion for it, and are going to continue to persevere and start their businesses and want to be out there selling food," Brooks said.

Here are a few highlights:

Viral orange chicken sandwich 

Long Beach-based Terrible Burger becomes Smorgasburg's new permanent burger vendor after standout appearances at LAist's Tournament of Cheeseburgers and the market's rotating Smorgasburger Stand. The smashburger pop-up, run by husband-and-wife team Nicole and Ryan Ramirez, specializes in burgers that draw from pop culture and global influences. They've made waves with a Korean barbecue burger topped with bulgogi barbecue sauce and a viral orange chicken sandwich, previously available only at their Tuesday night residency at Long Beach's Midnight Oil, making its L.A. debut Sunday.

"We have been big Smorgasburg fans for a really long time before we even started Terrible Burger. We would go to Smorgasburg on dates, just eat and hang out. And it was just always a little dream of, "oh, what if we ever sold food here?" Nicole Ramirez said.

Crispy fried snapper and thick-cut fries 

Orange County-based Hot Grease, run by Asha Starks, is among four vendors graduating from residencies to permanent status. The Southern fried fish pop-up celebrates Black American history through food that honors Starks' family heritage.

"Folks often forget that there are Black folks in Orange County. My family came to Orange County during the second wave of the Great Migration, and they settled in Santa Ana... my food is very cultural. And the story, I feel like, is just as important to highlight," Starks said.

Hot Grease serves crispy buttermilk fried snapper with thick-cut fries and small-batch sauces like "Ill Dill" tartar. Honoring the fish fry's history as a site of mutual aid, Starks directs 3% of sales to the Potlikker Line, Hot Grease's reproductive justice mutual aid fund. For January, she's added fish and grits, black-eyed peas and collard greens.

Pizza with a Persian twist

Mamani Pizza, from the Grammy-nominated producer Farsi, part of the music production team Wallis Lane, started making Neapolitan-style pizzas at his West L.A. recording studio a year ago. What began as late-night pies for friends and artists became an underground hit. Most pizzas are traditional, but Farsi adds Persian touches like The Mamani, topped with ground wagyu koobideh, roasted Anaheim chilis, Persian herbs and pomegranate molasses.
