It acts as a guide for state agencies and the legislature…

Air pollution is not just a problem for lungs. Increasingly, research suggests air pollution can influence childhood behavioral problems and even IQ. A new study led by the University of Washington has added evidence showing that both prenatal and postnatal exposure to air pollution can harm kids. The study, published in Environmental Health Perspectives, found that children whose mothers experienced higher nitrogen dioxide (NO2) exposure during pregnancy, particularly in the first and second trimester, were more likely to have behavioral problems….

Forest fire smoke can make you sick, and we’re experiencing more them. In terms of public health, it seems logical to reduce forest fires to limit unhealthy air pollution, but forest managers are increasingly seeing prescribed burning as an essential tool to reduce explosive wildfires. How should we plan to deal with the impacts of these fires?

All forest fire smoke is bad for people, but not all fires in forests are bad. This is the conundrum faced by experts in forest management and public health: Climate change and decades of fire suppression that have increased fuels are contributing to larger and more intense wildfires and, in order to improve forest health and reduce these explosive fires, prescribed and managed fire is necessary.
