Evaluation of hexavalent chromium in sediment pore water of the Hackensack River, New Jersey, USA.
ENVIRONMENTAL TOXICOLOGY AND CHEMISTRY(2010)
摘要
Pore water was collected from in situ passive samplers in Hackensack River sediments adjacent to a chromite ore processing residue site in Kearny, New Jersey. Although the sediments at this site contained more than 3,000 mg/kg of total chromium (Cr) and shallow groundwater adjacent to the shore contained more than 1,000 mu g/L of hexavalent Cr [Cr(VI)], concentrations of dissolved total Cr and Cr(VI) in pore water (PW) samples were less than ambient water quality criteria for Cr(VI) (50 mg/L). Concentrations of dissolved total Cr in pore water ranged from <2.0 to 5.3 mu g/L, while Cr(VI) was not detected (<10 mu g/L). These findings are consistent with previous studies, which demonstrated limited bioavailability and toxicity of Cr in sediment at this site and others with similar conditions. Environ. Toxicol.
