A bioassay that uses chicken embryo hepatocyte (CEH) primary cultures for measuring 2, 3,
7, 8-tetrachlorodibenzo-p-dioxin equivalent (TCDD-EQ) concentrations in extracts prepared …

Fish-eating waterbirds from the Great Lakes of North America have shown symptoms of
poisoning similar to those observed in laboratory exposures of various avian species to …

Abstract Concentration‐dependent effects of 2, 3, 7, 8‐tetrachlorodibenzo‐p‐dioxin (TCDD),
2, 3, 4, 7, 8‐pentachlorodibenzofuran (PeCDF), and 2, 3, 7, 8‐tetrachlorodibenzofuran …

The environment has become contaminated with complex mixtures of planar, chlorinated
hydrocarbons (PCHs) such as polychlorinated biphenyls (PCBs), polychlorinated dibenzo-p …

During the1992 breeding season, eggs of bald eagles (Haliaeetus leucocephalus) were
collected within a gradient of exposure to chlorinated hydrocarbon pollutants, particularly …

In recent years contamination of the Great Lakes ecosystem with planar chlorinated
hydrocarbons (PCHs) has attracted considerable concern due to their known reproductive …

Given the wide variation in methodology (different chemical analyses and bioanalytical
methods) and uncertainty regarding quality assurance and control across laboratories …

There is a strong need for the development of relatively rapid and low-cost bioassays for the
determination of polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDD/Fs), and …

A bioassay for future use for dioxin risk assessment is presented. Dose effect relationships
are set up for 2, 3, 7, 8-TCDD, 1, 2, 3, 7, 8-PeCDD, 1, 2, 3, 4, 7, 8-HxCDD, 1, 2, 3, 6, 7, 8 …

Liver concentrations of polychlorinated biphenyls (PCBs) and chicken embryo hepatocyte
