The QWASI fugacity mass balance model has been widely used since 1983 for both
scientific and regulatory purposes to estimate the concentrations of organic chemicals in …

We present a model to predict the long-term distribution and concentrations of
perfluorooctanoic acid (PFOA) and perfluorooctanesulfonic acid (PFOS) in estuaries …

Elevated contaminant levels in the North American Great Lakes have resulted in restrictive
fish consumption advisories. Avoiding the risks associated with fish consumption may also …

Spatiotemporal trends for polychlorinated biphenyls (PCBs) were examined in surface and
suspended sediments collected between 1994 and 2018 from over twenty nearshore …

Abstract Analysis of aquatic ecosystem data collected from large water bodies must consider
spatial variations. A suite of pelagic survey stations exists for the Laurentian Great Lakes, but …

Organisms have long been treated as receptors in exposure studies of polychlorinated
biphenyls (PCBs) and other persistent organic pollutants (POPs). The influences of …

Distribution of pesticide residues in the environment and their transport to surface water
bodies is one of the most important environmental challenges. Fate of pesticides in the …

Watershed mercury (Hg) flux was calculated for ten inflowing rivers and the outlet for Lake
Ontario using empirical measurements from two independent field-sampling programs. Total …

An essay is presented regarding the bioaccumulation modeling in benthic food chains. The
authors say that organic compounds such as toxaphene, DDT and polychlorinated …

The first application of organochlorine pesticides such as DDT and Dieldrin dates back to
1956 and 1961, respectively, but due to the long half-life and their bio-accumulation in …
