Nationwide decadal source apportionment of PM2.5 with a focus on iron
Fine particulate matter pollution (PM2.5) has detrimental effects on human health, visibility, and the environment. One component of PM2.5, aerosol-phase iron, also has a multi-faceted effect on climate. In its largely insoluble iron oxide form, found in dust aerosol, it absorbs shortwave radiation. Emissions from anthropogenic processes, primarily industry and coal combustion, also contain iron, with most of that iron in soluble forms. Soluble iron is an important phytoplankton nutrient and thus its atmospheric abundance is intertwined with carbon sequestration. To ascertain the various sources ...
