Assessment of Hg Exposure in Terrestrial Environments

This DuPont presentation (Science Advisory Meeting, Dec 11, 2002) reviews mercury (Hg) exposure in terrestrial environments. It outlines a literature review, floodplain land‑use appraisal, and a floodplain Hg survey (surface to 50 cm; total and species), discusses soil‑Hg levels of concern (including EPA 503 biosolids regulations), and describes plant uptake surveys and greenhouse/field studies.
