Arsenic geochemistry in three soils contaminated with sodium arsenite pesticide : An incubation study

Abstract

The potential for human exposure to arsenic (As), a group A carcinogen, has increased tremendously because of the encroachment of suburban areas into former agricultural lands, where arsenical pesticides were used extensively prior to the 1990s. Many baseline risk assessments of As-enriched sites assume that all (100%) As present in the soil is bioavailable… (More)
