Anthropogenic changes to mercury and lead biogeochemistry in forest soils across the Northeastern United States / by Justin Byron Richardson
Understanding mercury (Hg) and lead (Pb) accumulation and retention in forest soils is needed to reduce their negative impacts on human and wildlife health. In addition, mercury and lead can be used to characterize the role of soil in terrestrial...
