organochlorine compounds such as, polychlorinated biphenyls and organochlorine pesticides are among the best known classes of contaminants because of their potential for magnification and harmful biological effects. in this study, the amounts of organochlorine pesticides including d.d.t and its metabolites, α, β and γ-hchs isomers, σcyclodiene (endosulfan, heptachlor, heotachlor epoxide, aldrin...

Flannigan, and Nick Erdman. Thanks to Richard specifically for offering endless assistance and support in spite of many difficulties I encountered along the way. Above all, I would like to thank Jerry Schnoor for his guidance throughout the course of my graduate studies. In addition, I would like to thank all the amazing professors that comprise the Environmental Engineering department and thei...

Prenatal exposures to organophosphate pesticides and polychlorinated biphenyls have been associated with abnormal neonatal behavior and/or primitive reflexes. In 1998-2002, the Mount Sinai Children's Environmental Health Center (New York City) investigated the effects of indoor pesticide use and exposure to polychlorinated biphenyls on pregnancy outcome and child neurodevelopment in an inner-ci...

The entire nucleotide sequences (6.8 kilobase pairs) of the bphABC genes and their products involved in the initial dioxygenation and ring-meta-cleavage of biphenyls and polychlorinated biphenyls were determined. The first bphA gene starts about a 100 base pairs downstream from the transcriptional initiation site. The bphA region, which encodes a cluster of enzymes including biphenyl dioxygenas...

The hydrodehalogenation of polychlorinated phenyls and biphenyls (PCBs), catalysed by palladium N-heterocyclic carbene complexes, proceeds with excellent yields, at very low catalyst loadings and at room temperature, using isopropanol as the hydrogen source and NaOH as the base.
