Theres another reason PM2.5 is used to make health recommendations: It defines the cut off for particles that can travel deep into the lungs and cause the most damage. Where the research falls short is understanding how prolonged smoke exposure from wildfires affects the general population. Initially, Miller expected the animals to develop asthma or other common respiratory ailments. Here are some of the take-homes: Like other types of smoke from building fires or even cigarettes, wildfire smoke contains a mixture of particulate matter, carbon monoxide, and volatile chemicals. In fact, a nationwide study found that even a small increase in PM2.5 from one US county to the next was associated with a large increase in the death ratefrom COVID-19. That doesn't include people in less-populated states like Idaho, Montana and Colorado, where smoke was so thick in places that school classes, moved outdoors because of the pandemic, had to reverse course and head inside.

The most dangerous part of wildfire smoke, says Lisa Miller, an immunologist at UC Davis, is the particulate matter. Smoke inhalation incidents usually occur if a person gets trapped in a smoke or fire accident and ingests harmful smoke particles. Children are especially vulnerable, as ambient air pollution exposure during early childhood is associated with reduced lung function. MICKLEY: Thats a good question.
