Wildfire smoke is a mix of gases and fine particles from burning trees and plants, buildings, and other material. Hagler said most of what experts can theorize about repeatedly breathing wildfire smoke comes from what the science generally says about long-term PM 2.5 exposure. Enriched pathway analyses for differentially methylated regions (DMRs). Even someone who is healthy can get sick if there is enough smoke in the air. Although particle pollution is a principal public health threat from short-and longer-term exposure to wildfire smoke, it is important to keep in mind that wildfire smoke is a complex mixture that consists of other pollutants that have also been shown to lead to a variety of health effects.
