It was late August when I got a call from a grandmother. She lives in Seeley Lake, Montana, and she has heard we have air purifiers (净化器) with high-efficiency particulate air (HEPA) air-cleaners that can help with smoke. She needs one for the baby’s room. I explained we didn’t have any and told her how to purchase one.
She coughed and went silent with disappointment before asking how much they cost. Almost every person I talk to in Seeley Lake has this cough. “The family doesn’t have much money,” she said, but she promised to order a filter for the child. Small filters—ones that can clean a bedroom of up to 75 square feet—cost about $70 each.
The next day, the wildfire that had been burning for weeks in the Lolo National Forest, northeast of town, moved closer to the woman’s neighborhood, and the county sheriff’s office evacuated (疏散) the area. I wondered whether the air-cleaner would be there when the family returned home. I knew the smoke would be.
As an air-quality specialist with the Missoula City-County Health Department in Montana, my job is to understand air pollution, control it as much as possible, and help people protect themselves from its effects. I focus on smoke management: issuing permits for outdoor burns and updating residents about what to expect from the smoke when wildfires send it our way.
Never had we seen so many wildfires so close to home for so many weeks. There are six classes on the Environmental Protection Agency’s Air Quality Index (指数): good, moderate, unhealthy for sensitive groups, unhealthy, very unhealthy, and dangerous. Seeley Lake’s air reached dangerous class in 18 days last summer.
Last year was troubled by wildfires around the country. The fires that struck Northern California alone killed 44 people and caused more than $9 billion in damage. But this isn’t just a recent problem, nor is it limited to the West. Wildfires hit 49 states in 2017, including a swath from Florida to Virginia. More than 9 million acres burned nationwide, compared with the yearly average of 6.5 million acres.
