Validation of Aquatox 1.68 for Predicting Bioaccumulation of Pcbs in the Lake Ontario Food Web
ثبت نشده
چکیده
Certain chemicals are persistent in aquatic systems and tend to accumulate in the tissue of fish and other aquatic organisms, sometimes to levels that make them unsafe for human or wildlife consumption. The “bioaccumulative” compounds, such as polychlorinated biphenyls (PCBs), are the cause of a significant number of advisories against fish consumption throughout the U.S. Exposure to bioaccumulative compounds may be through water, contaminated sediment, or diet.

ABAM, a model for bioaccumulation of POPs in birds: validation for adult herring gulls and their eggs in Lake Ontario.
An Avian BioAccumulation Model (ABAM) of persistent organic pollutant (POP) uptake and elimination in adult life-stage of birds was validated by simulation of concentrations of DDE, dieldrin, mirex, and HCB in herring gull eggs in Lake Ontario for the years 1985, 1990, and 1992. These chemicals represented a range of whole-body half-lives of 82-265 days in the gull. Dietary intake of POPs by a ...
متن کاملPreferential biomagnification of aryl hydrocarbon hydroxylase-inducing polychlorinated biphenyl congeners in the Lake Michigan, USA, lower food web.
Preferential biomagnification of 14 dioxin-like polychlorinated biphenyls (PCBs) was determined in lower-trophic-level organisms of the Lake Michigan, USA, food web. Bioaccumulation of these coplanar, aryl hydrocarbon hydroxylase (AHH)-inducing PCB congeners and total PCBs in phytoplankton, zooplankton, Mysis relicta, and Diporeia sp. were studied for two locations in Lake Michigan over time. T...
متن کاملIsomers of dechlorane plus in Lake Winnipeg and Lake Ontario food webs.
The extent of bioaccumulation of the syn- and anti-isomers of Dechlorane Plus (DP) is assessed in archived food web samples from Lake Winnipeg and Lake Ontario. Concentrations of the isomers were determined using purified analytical solutions of individual isomers as opposed to the technical mixture. The syn-isomer was consistently detected in all samples from both lakes; the anti-isomer was de...
متن کاملA comparison of the transport and fate of polychlorinated biphenyl congeners in three Great Lakes food webs.
A food web bioaccumulation model was used to compare transport and fate of polychorinated biphenyls (PCB) congeners in three food webs in the Laurentian Great Lakes of North America. The model was used to quantify the contribution of sediment-derived and freely dissolved PCBs to the body burden of aquatic biota. In eastern Lake Erie (OH, USA), almost 100% of the chemical body burden of biota or...
متن کاملAccumulation of atmospheric and sedimentary PCBs and toxaphene in a Lake Michigan food web.
Seston, sediment, settling organic matter, and food web members were collected from Grand Traverse Bay, Lake Michigan, between April 1997 and September 1998 to examine PCB and toxaphene biomagnification. Stable isotopes of nitrogen and carbon were analyzed in samples and used to establish trophic structure of the food web and to determine the importance of atmospheric versus sedimentary sources...
