Annual premature deaths attributed to increased atmospheric PM2.5 from agriculture. Five alternate categorizations (columns) are shown: pollutant, process, commodity, product, and source. Pollutants include primary PM2.5 and secondary PM2.5 formed from precursor gases (NH3, NOx, NMVOCs, and SO2). The height of each black bar within each column corresponds to the number of attributed deaths; deaths within each column sum to 17,900.
