O-25: The Effect of Environmental Contaminants Endocrine-Disrupting PBBs and PBDEs on Reproduction and Fertility Outcomes

Background: Polybrominated Biphenyls (PBBs) and Polybrominated Diphenyl Ethers (PBDEs) are semi-permanent Halogenated compounds that are mainly used in flame retardant. These contaminants as endocrinedisrupting associated with dysfunction of immune, endocrine and nervous systems. Influence various physiological processes such as menarche, birth weight, fetus growth and development, head circumf...

Preliminary hazard assessment of polychlorinated biphenyls, polybrominated diphenyl ethers, and polychlorinated dibenzo-p-dioxins and dibenzofurans to Yangtze finless porpoise in Dongting Lake, China.

Yangtze finless porpoise (Neophocaena phocaenoides asiaeorientalis), a protected endangered species, is the sole freshwater subspecies of finless porpoise, living only in the middle and lower reaches of the Yangtze River, China, and its appended lakes. Its population has decreased sharply to 1,400 because of human activities, including environmental contamination. In the present study, polychlo...

Toxicity of polybrominated biphenyls (PBBs) in Domestic and laboratory animals.

The composition, environmental fate, and effects of the polybrominated biphenyls (Firemaster BP-6 or FF-1) involved in the accidental contamination of cattle feed in Michigan in 1973 are reviewed. Toxic effects referred to in this report are limited to those occurring in domestic and laboratory animals and include general toxicity, neurobehavioral toxicity, immunotoxicity, reproductive toxicity...

Association studies of polybrominated biphenyls in aquatic systems.

Most of the studies on polybrominated biphenyls (PBB) have been on toxicological evaluations. Very few studies have dealt with their persistence and concentration potential in several environmental matrices such as soil, sediments, and biota as a function of matrix properties. The understanding of these relationships will form some basis for assessing the characteristics of the contaminant's be...
