Smoke from California’s raging wildfires spreads a public health emergency across the Bay Area
As you might have heard, those of us who live in the Bay Area are breathing air this week that rivals Beijing’s, thanks to the fires raging across Northern California. West Oakland deals with bad air quality all the time, so I reached out to some folks there seeking perspective.
Margaret Gordon, a local grassroots activist, suggested I talk to Eryk Maundu. He’s a techie-turned-urban farmer who takes a data-driven approach to agriculture, and he had an inkling before most of us that something very bad was happening to the Bay Area’s air.
Just last week, he put up some new air quality sensors around his food plots. They registered a huge spike in contamination levels on Sunday night — three times worse than when he had tested the sensors around some friends who smoke. “I never thought I’d see it go higher than that,” he told me.
Maundu thought he might have to throw the sensors out, until news broke Monday morning of wildfires tearing through Napa and Sonoma counties, about 50 miles north of San Francisco. Within the next few days, all of us in the Bay Area could see the same thing Maundu’s sensors were telling him: Our air was unhealthy to breathe.
“The numbers are off the charts,” says Walter Wallace with the Bay Area Air Quality Management District. The big health concern: Particulate matter carried by the smoke sticks to our lungs and can cause breathing and other health problems. “It’s so small that our bodies can’t defend against it.”
Suddenly, everyone in the region is getting double dose of what the air is like in parts of West Oakland, where one of the country’s busiest ports brings in a steady stream of truck traffic, nearby highways ferry tens of thousands of cars every day, and asthma rates are some of the highest in the state. On Thursday, the air quality throughout Oakland was second-worst in the nation behind Napa, where fires raged.
More than 20 blazes consumed more than 200,000 acres of land statewide, largely north of the Bay Area, where at last count 31 people have died, close to 500 are missing, and 90,000 have been displaced. The largest of the fires, the so-called Tubbs fire, which is primarily raging in Sonoma County, was just 25-percent contained as of Friday morning, according to the California Department of Forestry and Fire Protection.
The fires have destroyed homes and businesses in the region north of San Francisco often called “wine country.” In the Bay Area — including Oakland, where I live — we’ve been told to stay indoors. It’s a tall order in a part of the country where the predictable weather and the natural beauty begs residents to be outside. And our current predicament may continue through this weekend.
Anthony LeRoy Westerling, an environmental engineering professor at the University of California, Merced, says that wildfires are bigger, more frequent, and burn for longer now than they did in the 1980s. You’ll never guess what Westerling concludes is behind this phenomenon: A warmer climate that dries out forests.
More fires means more destruction where they burn — and more intolerable air downwind.
The smoke blowing into the Bay Area has prompted a run on 3M N95 Particulate Respirator masks and air purifiers. Many who have the means have taken spontaneous road trips south or east to flee the particulate matter readings hovering around five times normal. Others are reporting headaches and respiratory problems. I suffered from childhood asthma, and spending about 10 minutes outside without a mask, breathing in air that smells like a campfire, made my lungs feel heavy.
All of this sent me to the Ace Hardware on 3rd St and Martin Luther King Jr. Way in West Oakland, where I joined a flow of customers buying N95 masks that sold for $2 a piece (I bought 12). The store has sold tens of thousands of masks in the past few days, struggling to try to keep up with demand.
“Yesterday morning was the big push, and then today has been even bigger,” the store’s general manager, Brian Altwarg, told me on Thursday. “And from what I see on the news, it’s going to get worse before it gets better.”
Florine Mims has lived in the area for nearly 60 years, and she arrived at the Ace around 2 pm on Thursday, riding and then pushing her electric wheelchair after its battery lost its charge. She has a number of health problems, including asthma, and hoped getting a mask would bring her some relief.
“They gave me two,” she says about the N95 masks she carried out of the store. “I’m hoping they’ll help me breathe better.”
Mims, and a significant percentage of West Oakland residents, are the group most at risk over the remaining days if fire containment, a change in wind direction, or rainfall doesn’t help clear out the noxious air, says John Balmes, a medical doctor and environmental health scientist at the University of California, Berkeley.
“A week of exposure to this level, it’s going to affect people with preexisting asthma, but it won’t cause their asthma to stay bad,” Balmes says. “They have bad pollution all the time in a lot of the megacities in Asia.”
Although the regular air quality readings in West Oakland don’t quite rival those in places like Beijing or New Delhi, its residents are used to living with pollution. The community recently filed a federal civil rights complaint against the port of Oakland and the city for discriminating against the largely black part of town by allowing more development to creep into the area and ignoring pleas to monitor air quality.
For now, though, the experience of breathing in dirty air is a shared burden for people in the Bay Area. And that’s an irony that isn’t lost on those living in West Oakland, like Margaret Gordon.
“This whole thing with the fire was a real equalizer for everybody,” she says.
