Yong Qian et al.
Environmental monitoring and assessment, 116(1-3), 157-167 (2006-06-17)
The contamination of organochlorine pesticides hexachlorocyclohexane (HCH) and Dichlorodiphenyltrichloroethane (DDT) and their eco-environmental assessment in surface sediments from Lake Dongting, the second-largest freshwater lake in China, were studied. Concentrations of summation HCH (=alpha-HCH + beta-HCH + gamma-HCH +delta-HCH) were 0.21-9.59
Poonam Sharma et al.
Applied and environmental microbiology, 72(9), 5720-5727 (2006-09-08)
Incubation of resting cells of Sphingobium indicum B90A, Sphingobium japonicum UT26, and Sphingobium francense Sp+ showed that they were able to transform beta- and delta-hexachlorocyclohexane (beta- and delta-HCH, respectively), the most recalcitrant hexachlorocyclohexane isomers, to pentachlorocyclohexanols, but only resting cells
Jun Wu et al.
Environmental microbiology, 9(9), 2331-2340 (2007-08-10)
Commercial formulations of hexachlorocyclohexane (HCH) consist of a mixture of four isomers, alpha, beta, gamma and delta. All these four isomers are toxic and recalcitrant pollutants. Sphingobium (formerly Sphingomonas) sp. strain BHC-A is able to degrade all four HCH isomers.
R Calvelo Pereira et al.
Environmental pollution (Barking, Essex : 1987), 155(2), 350-358 (2007-12-26)
This study focuses on the main routes of distribution and accumulation of different hexachlorocyclohexane (HCH) isomers (mainly alpha-, beta-, gamma- and delta-HCH) in a soil-plant-air system. A field assay was carried out with two plant species, Cynara scolymus L. and
E D Buck et al.
The Journal of pharmacology and experimental therapeutics, 289(1), 477-485 (1999-03-23)
Several isomers of hexachlorocyclohexanes (HCHs) have been shown to be toxic to mammals. Previous studies have revealed that the delta isomer (delta-HCH) was particularly potent toward disrupting Ca2+ homeostasis in a variety of excitable and nonexcitable cells and altering contractility
