Association studies of polybrominated biphenyls in aquatic systems

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...

Immunological studies in cattle exposed to polybrominated biphenyls

The intactness of the immune system in cattle exposed to polybrominated biphenyls (PBBs) has been investigated by using several immunoassays. Eighty-seven animals have been studied, 35 control animals (not exposed to PBBs) and 52 animals exposed to PBBs (0.02-30 ppm/g fat equivalent). The immunoassays included a complete blood count, identification of peripheral blood T and B lymphocyte subpopu...

Polybrominated diphenyl ethers and polybrominated biphenyls in Australian sewage sludge.

This paper presents a brief review of the international scientific literature of polybrominated diphenyl ethers (PBDEs) and polybrominated biphenyls (PBBs) in sewage sludge and a survey of these compounds in sewage sludge from 16 Australian wastewater treatment plants (WWTPs). The SigmaPBDE mean concentration in the Australian study was 1137microgkg(-1) dry weight (d.w.) (s.d. 1116) and ranged ...
