It was concluded that the TEF concept is still the most plausible and feasible approach for risk assessment of halogenated aromatic hydrocarbons with dioxinlike properties.
Ecotoxicological Risk Assessment for Roundup ® Herbicide
Glyphosate-based weed control products are among the most widely used broad-spectrum herbicides in the world. The herbicidal properties of glyphosate were discovered in 1970, and commercial…
Global distribution of perfluorooctane sulfonate in wildlife.
Fish-eating, predatory animals such as mink and bald eagles contained concentrations of PFOS that were greater than the concentrations in their diets, suggesting that PFOS can bioaccumulate to higher trophic levels of the food chain.
Ecological risk assessment of atrazine in North American surface waters.
The triazine herbicide atrazine (2-chloro-4-ethylamino-6-isopropyl-amino-s-triazine) is one of the most used pesticides in North America. Atrazine is principally used for control of certain annual…
Toxicity Reference Values for the Toxic Effects of Polychlorinated Biphenyls to Aquatic Mammals
Threshold tissue residue concentrations of polychlorinated biphenyls and 2,3,7,8-tetrachlorodibenzo-p-dioxin equivalents and TEQs were derived from the published results of semi-field or field toxicity studies conducted with seals, European otters and mink.

E eggs of fish contained notable concentrations of PFOS, suggesting oviparous transfer of this compound, and the biomagnification factor (BMF) of perfluorinated compounds in higher trophic-level organisms such as salmonid fishes, mink, and eagles were based on the concentrations in livers or plasma.
Occurrence of butyltin compounds in human blood
Concentrations of butyltin compounds measured in blood were less than that affected human natural killer lymphocytes (a primary immune defense against...
Analytical Methods for Detection of Selected Estrogenic Compounds in Aqueous Mixtures
Both natural estrogens and synthetic compounds that mimic estrogen can reach the aquatic environment through wastewater discharges. Because nonylphenol (NP), octylphenol (OP), nonylphenol…

There is presently little information on the chemical–physical properties of most PFCs, and even less toxicity information is available on these compounds.
Species-specific recombinant cell lines as bioassay systems for the detection of 2,3,7,8-tetrachlorodibenzo-p-dioxin-like chemicals.

Overall, these recombinant cell lines can be used for the detection and relative quantitation of AhR agonists/antagonists in complex mixtures of environmental and biological samples, for identification and characterization of novel Ah R agonists, and for examination of species differences in PCDH responsiveness.
