Influence of trophic position and spatial location on polychlorinated biphenyl (PCB) bioaccumulation in a stream food web.

Abstract

We tested the ability of delta15N-derived trophic position (TP) to predict polychlorinated biphenyl (PCB) concentrations in a historically contaminated stream (Twelvemile Creek, SC). We analyzed sediment, four types of organic matter, 27 macroinvertebrate taxa, and 25 fish species from six sites spanning 25 stream km. SigmaPCBs were high across sites (mean… (More)
