ASSESSING BENTHIC BIOACCUMULATION OF POLYCHLORINATED DIOXINS/FURANS AND POLYCHLORINATED BIPHENYLS IN THE LOWER PASSAIC RIVER (NJ, USA) BASED ON IN SITU PASSIVE
Khairy, M.A, and R. Lohmann.
Environmental Toxicology & Chemistry 39(6):1174-1185(2020)
A low-density polyethylene (LDPE) multisampler system was deployed at four locations in the Lower Passaic River to derive freely dissolved concentrations of polychlorinated dibenzo-p-dioxins/furans (PCDD/Fs) and PCBs in in situ pore water versus ex situ river water. The multisampler also collected sediment and benthic species samples. Good agreement was generally observed for PCDD/F and PCB concentrations comparing in situ and ex situ approaches (within 0.30-39%). Significant linear relationships were derived between log LDPE-based and log lipid-based concentrations of PCDD/Fs and PCBs. The in situ multisampler system showed promise to derive hydrophobic organic contaminant (HOC) concentrations in porewater and river water and to predict the bioaccumulation potential of HOCs in benthic biota.
