Atmospheric fine particulate matter (PM) transports polycyclic aromatic hydrocarbons (PAHs) regionally and globally, influencing the air quality of communities around the planet. Concentrations of 130 PAHs extracted from PM, collected on a Native American Tribal Reservation in the Northern Puget Sound region of the American Pacific Northwest, were used to assess the air quality impacts of regional and local PAH sources, atmospheric transport, and human health implications. Wind coming from the southeast of the sampling locations increased the overall PAH concentration of the PM, while winds from the southwest decreased the PAH concentration. Read More
