Journal ArticleDOI
Stable nitrogen isotopes as indicators of anthropogenic activities in small freshwater systems
James L. Lake,Richard A. McKinney,Frank A. Osterman,Richard J. Pruell,John Kiddon,Stephan A. Ryba,Alan D Libby +6 more
TL;DR: Investigation of food chain length and trophic position across sites affected by differing levels of anthropogenic activity indicated that δ15N was a valid descriptor of eutrophication at sites with low dissolved inorganic nitrogen concentrations.
Journal ArticleDOI
Uptake and depuration of organic contaminants by blue mussels ( Mytilus edulis ) exposed to environmentally contaminated sediment
TL;DR: Comparisons of the uptake and depuration of polycyclic aromatic hydrocarbons and polychlorinated biphenyls in blue mussels revealed that the bioconcentration factors for PCBs were higher than those of PAHs when compounds with similar n-octanol/water partition coefficients were compared.
Journal ArticleDOI
Geochemical study of sediment contamination in New Bedford Harbor, Massachusetts
Richard J. Pruell,Curtis B. Norwood,Robert D. Bowen,Warren S. Boothman,Peter F. Rogerson,Murray Hackett,Brian C. Butterworth +6 more
TL;DR: In this article, chemical analyses of sediment samples collected along a transect in New Bedford Harbor revealed a gradient of increasing concentrations of polychlorinated biphenyls (PCBs), polychlorined dibenzo-p-dioxins (PCDDS) and several trace metals from the southern to the northern areas of the estuary.
Journal ArticleDOI
Accumulation of Polychlorinated Organic Contaminants from Sediment by Three Benthic Marine Species
TL;DR: Although final contaminant concentrations were highest in the sandworms, AFs were generally higher for the clams and shrimp and lower for the sand worms, and a recently identified sulfur containing analog of tetrachlorinated dibenzofurans, 2,4,6,8-tetrACHlorodibenzo-p-dioxin (2,3, 7, 8-TODD), accumulated in the three species.
Journal ArticleDOI
Evaluation of selected lipid methods for normalizing pollutant bioaccumulation
TL;DR: It is shown that significantly different lipid concentrations are found when using common, but different, extraction solvents and methods, and models that estimate tissue pollutant concentrations normalized to lipid will give significantly different bioaccumulation estimates.
