The Availability and Bioaccumulation of Sedimentary 2,3,7,8-TCDD and Other Persistent Bioaccumulative Toxic Compounds in the Lower Passaic River
Hudson River Foundation Grant Drs. Weinstein and Lohmann (University of Rhode Island), Co-Principal Investigators, have been awarded a $209,000 Hudson River Foundation Grant, The Availability and Bioaccumulation of Sedimentary 2,3,7,8-TCDD and Other Persistent Bioaccumulative Toxic Compounds in the Lower Passaic River. The main objectives of the proposed research are to better understand the availability, cycling and bioaccumulation of persistent organic pollutants, with a focus on 2,3,7,8-TCDD, in the lower Passaic River. Passive samplers will be deployed along the lower Passaic River to directly measure the freely dissolved pollutants in water, atmosphere and porewater. Various biota (blue crabs and fish) will also be sampled along a salinity gradient covering the lower Passaic River to determine bioaccumulation factors (BAFs) for PCBs, PCDD/Fs and emerging PBTs relative to dissolved concentrations in the water column. A trophodynamic and stable isotope approach will be adopted to predict concentrations in individual components of the foodweb based on life history and feeding strategies.
