  1. Assessment of the human health risks posed by exposure to chromium-contaminated soils.

    Article - En anglais

    Millions of tons of chromite-ore processing residue have been used as fill in various locations in northern New Jersey and elsewhere in the United States.

    The primary toxicants in the residue are trivalent chromium [Cr(III)] and hexavalent chromium [Cr(VI)]. The hazard posed by Cr(III) is negligible due to its low acute and chronic toxicity.

    In contrast, Cr(VI) is a human carcinogen following inhalation of high concentrations.

    It can also cause allergic contact dermatitis.

    This evaluation addresses a residential site where the arithmetic mean (x) and geometric mean (gm) concentrations of Cr(III) in soil were 2879 and 1212 mg/kg (ppm).
