A recent article by EOS writer Jackie Rocheleau highlights a growing concern about wildfire smoke and other pollutants that continue to exist in a diluted quantity within our atmosphere. With wildfires growing in size and quantity due to climate change, the original idea that simply waiting for the pollutants to disperse would be enough to protect human health, is coming into question. 

Work out in polluted air and you may miss out on some of the brain benefits of exercise, according to two, large-scale new studies of exercise, air quality and brain health...

Year after year California has seen some of the largest and most deadly wildfires, not only by acreage burned, but by also by hazardous air quality. The smoke has turned some cities in neighboring state’s air quality into the dirties in the world, including outside of the state.

Last week, Michael S. Regan, Administrator of the US Environmental Protection Agency, announced that the EPA will reconsider strengthening the limits and standards for fine particulate matter.

Over 111 million metric tons of CO2 were emitted by wildfires in California for the 2020 year. The transportation sector is the only area to have emitted more carbon dioxide at over 169 million metric tons. While from the outset, that looks pretty bad, you may still wonder, "In actuality, how bad is the wildfire smoke for Climate Change?"

In an interview with the SF Chronical, AQRC Director, Tony Wexler, stated that the wildfire carbon emissions are of almost no concern for him in relation to climate change.

It’s widely known through the Air Quality Research Center that outdoor air pollution leads to untimely deaths throughout the world, however, a recent publication by Dr. Erwan Monier, Associate Professor of Climate Change Impacts in the Department of Land, Air and Water Resources, and associates demonstrated that many of these deaths are a result of cross-state air pollution. 

A recent collaborative study between Harvard and UC Davis produced data backing the notion that nanoparticles (NP) more frequently crossed the air-blood lung barrier to the rest of the body in infant rats than adults. Fascinatingly, this higher permeability demonstrates immature lungs do not follow the same directives as mature lungs.
