Organochlorine Pesticides and Polychlorinated Biphenyls in Human Adipose Tissue*

Investigation of organochlorine pesticides (OCPs) in mollusks collected from coastal sites along the Chinese Bohai Sea from 2002 to 2004

“…For HCHs, generally, the commercial mixtures contain 60e 70% a, 5e12% b, 6e10% g, and 3e4% d (Kutz et al, 1991). While, Fig.…”

Pseudomonas sp. to Sphingobium indicum: a journey of microbial degradation and bioremediation of Hexachlorocyclohexane

“…The process results in the production of technical grade HCH which is a mixture of all its isomeric forms in varying proportions. Technical HCH thus basically consists of fi ve stable isomers viz., α-(60-70%), β-(5-12%), γ-(10-12%), δ-(6-10%) and ε-(3-4%) [11,12]. All HCH isomers are stereochemically different from each other ( Fig.…”

The enzymatic basis for pesticide bioremediation

“…The insecticidal γ-isomer of hexachlorocyclohexane (γ-HCH, commonly known as lindane) and technical HCH (which includes α-, β-, γ-, ε-and δ-isomers) [72] have been used extensively against agricultural pests, and in malaria control programs, worldwide. The indiscriminate use and large-scale production of HCH during the past 50 years has generated dangerous stockpiles of highly persistent toxic wastes, which are illegally disposed of in the countryside, water bodies and agricultural fi elds in several countries.…”
