The main difference between air quality sensors in the western United States warns people of wildfire smoke emergencies, creating blind spots that primarily affect high-risk communities during large-scale wildfires in the summer.
When air quality becomes unsafe, public health officials in western states are trying to find a way to alert more remote communities—including migrant workers, indigenous tribes, people in houses without air filters, and the elderly.
The U.S. Environmental Protection Agency announced on Wednesday that it will provide officials with a $7 million investment to help them research better strategies and tools to improve smoke detection.Researchers in Stanford University with University of CaliforniaBerkeley, will come up with a system to communicate with low-income and hard-to-reach communities to protect them from wildfire pollution.
Tom Roick of the Oregon Department of Environmental Quality said: “We are seeing wildfire smoke becoming more common and more intense.” “It’s not because we have more monitoring; it’s getting worse.”

Gas stations are mainly concentrated around major cities on the West Coast and east of the Mississippi River-this intricate relationship makes it impossible for some people to determine the local risk of smoke, including rural areas where air quality will rapidly decline in the event of a fire nearby. This problem extends far beyond the line of fire, because wildfire smoke can travel thousands of miles and lose its obvious smell, but it still poses a threat to public health.
The monitoring gap highlights what officials and public health experts say is that climate change has brought longer and destructive wildfire seasons to the western United States, southern Europe, and eastern Russia, leading to an apparent shortage of increasingly polluted resources.
The tiny particles in wildfire smoke can cause breathing problems, which are more serious for people with chronic diseases.Long-term effects are still being studied, but some researchers estimate that long-term exposure to smoke causes approximately 20,000 premature deaths in the United States each year
Sarah Cofield, an air quality expert in Missoula, Montana, said: “This is a very frustrating place. We often encounter health emergencies, but we don’t have enough coping methods.” “You can. Breathing smoke in your office and thinking you are okay because you are in it, but you are not.”
Missoula is located along the Clark Fork River, with about 75,000 people, surrounded by mountains, and notorious for its smoke traps. The entire area is similar to valleys, many valleys do not have pollution monitors, and the smog situation from one valley to another can vary greatly.
There are 19 permanent monitoring stations in Montana. This is approximately one area per 7,700 square miles (20,000 square kilometers) or almost as large as New Jersey. There are 30 such stations in New Jersey.
Air quality data in eastern Montana is particularly scarce. This month’s 266-square-mile (690-square-kilometer) fire in the Northern Cheyenne Indian Reserve produced severe smoke. When the air filter failed to filter, officials shut down a house. Health clinic. t keep up with pollution.
The smoke prompted the tribal authorities to protect the elderly and others at risk by extending the evacuation order for the lame deer, a small town of about 2,000 people located below the fire-scarred Badger Peak, where the tribal government building is located. .
But on the same day, the lame deer and surrounding areas were excluded from the pollution alert by state officials. They said the extremely high levels of smoke particles made the air in large areas of Montana unhealthy and advised people to avoid prolonged fatigue to protect their lungs. A pollution sensor on the reserve burned in the fire, about 30 miles (48 kilometers) from the nearest state Department of Environmental Quality monitor, and showed the air quality reading as “good.”
This allows tribal officials to judge pollution hazards based on the distance they can see—a rough step backward for areas without monitors. Tribal spokesperson Angel Becker said that on a scale from 1 to 20, “I would say that the smoke is 19”.
“What makes it difficult for a lame deer to sit between a few gullies is that,” she added. “So when you put on your socks [with smoke], It just sits here, which is not good for the elderly or children who suffer from asthma or any breathing problems. “
Children are also more prone to health problems.
Caitlin Kelly, a wildfire smoke pollution expert at the Washington Department of Health, said this is not a small part of society: People over 65 and children under 18 make up about 40% of the US population.
Doug Kuenzli, who oversees Montana’s air quality monitoring program, said that regulators recognize the need for more smoke data, but advanced monitors can be very expensive—$10,000 to $28,000 per unit.
Roick said Oregon has expanded its network in the past two years, installing five new monitors on the state’s picturesque coastline, where smog has only recently become a recurring problem.
The government plan to alert the public when smog pollution becomes unhealthy relies on approximately 950 permanent monitoring stations and dozens of mobile devices that can be deployed around major fires.
According to data from the US Environmental Protection Agency, the number of days of unhealthy air quality recorded by the National Pollution Monitor in 2021 is more than 10 times the number of days of unhealthy air quality recorded in each of the past two years. Officials say wildfires may be the main reason for this growth.
Rapid technological progress means that families can purchase their own monitoring equipment for approximately $250. Officials say these devices are not as reliable as government stations, but data from many private sensors are now displayed on interactive smoke exposure maps of the Environmental Protection Agency and Forest Service.
Although inaccurate readings from some consumer-grade sensors have been reported, officials say they can help fill blind spots in government networks. According to the EPA, the number of sensors in use is rapidly increasing-from approximately 6,000 private sensors last year to more than 10,000 today.
“There is still a gap,” Kelly said. “Low-cost sensors are the first step to fill in the gaps we don’t have [government] Monitor. “
In Missoula, a small non-profit organization set up to draw people’s attention to global warming issues is going beyond warning people about smog. It provides temporary air filters and portable air purifiers for homeless elderly and poor families.
Vinette Rupp, a 74-year-old Missoula woman who received a portable air purifier, said that when the smoke thickened in the city, she “almost could taste it.” Maureen Fogarty, a 67-year-old neighbor who has lung cancer and breathing problems, said that since she got one of the filters, her cough has eased.
“Well, this is a lifesaver, because I can breathe more easily now,” Fogarty said. “That’s the way it is, you know, you have to come and go, you bring unhealthy air, and it will affect you.”
Climate Smart Missoula, which provides portable air purifiers, also manufactures and distributes filters through local food banks. DIY purifiers cost about US$30 each—and the manufacturing unit is US$150 or more—this kind of do-it-yourself purifier has been approved by public health officials. They are made of box fans with high-efficiency furnace filters and are fixed on the back with tape to trap pollution particles as the air passes through.
Amy Cilimburg, director of the climate-smart Missoula, said that she and a colleague have built about 200, mostly through donations.
“Our strategy for dealing with wildfire smoke is to pray for rain, or leave the town, or suffer-this seems not enough,” Cilimburg said. “Although scientists told us it was coming, it kind of caught up with us. I think we Need to go to work.”
