Characterization of Selected Bed-Sediment-Bound Organic and Inorganic Contaminants and Toxicity, Bamegat Bay and Major Tributaries, New Jersey, 2012.

摘要

This report describes the methods and procedures used to determine the concentration of legacy and currently-used pesticides, trace elements, priority and alkylated PAHs, PCBs as Arochlor mixtures and individual PCB congeners, and sediment toxicity, as well as values for pH, specific conductance, organic carbon, total nitrogen, and grain size in sediment samples collected from estuarine sites and freshwater tributary sites within the Barnegat Bay watershed, N.J., during August September 2012. Sediment samples were analyzed for a suite of 94 currently-used pesticides, 21 legacy pesticides, 24 trace elements, 40 PAHs, 14 PCB Arochlors, and 145 PCB congeners. Concentrations of detected compounds are reported. Results are compared to Sediment Quality Guidelines (SQG) (Long and others, 1998), where available. Sediment toxicity and Phase I Sediment Toxicity Identification Evaluation (TIE) results are also reported. Percentages of dissolved organic carbon and total nitrogen, grain-size distributions, and values of sediment-quality characteristics are also presented.
