Pollution from eastern North Carolina’s hog industry has been studied for more than 30 years. Concentrated animal feeding operations (CAFOs) and their open waste storage pits emit two chemicals of particular concern to human health: ammonia (ammoniaNH3) and hydrogen sulfide (hydrogen sulfideH2S). Some previous studies of the region’s hog CAFOs focused on environmental injustice, noting that such facilities were disproportionately located near low-income communities of color. Going beyond these proximity-based analyses, a new study published in Environmental Health Perspectives applied a dispersion model for transport of ammoniaNH3 and hydrogen sulfideH2S over space and time to estimate human exposure.
