Novosphingobium lindaniclasticum LE124(T) is a hexachlorocyclohexane (HCH)-degrading bacterium isolated from a high-dosage-point HCH dumpsite (450 mg HCH/g soil) located in Lucknow, India (27°00'N and 81°09'E). Here, we present the annotated draft genome sequence of strain LE124(T), which has an estimated size of 4.86 Mb and is comprised of 4,566 coding sequences.

Pseudomonas aeruginosa MTB-1 does not degrade gamma-hexachlorocyclohexane (γ-HCH), but this bacterium persistently coexists with a γ-HCH-degrading strain, Sphingomonas sp. MM-1, in a microbial community enriched by the technical formulation of HCH. Here we report the complete MTB-1 genome sequence, with a 6.6-Mb circular chromosome.

El Diclorodifeniltricloroetano (DDT) y Hexaclorociclohexano (HCH) son disruptores endócrinos cuya presencia en la leche representa un riesgo para salud. Existe evidencia de que pasteurización disminuye o incrementa concentración plaguicidas organoclorados productos lácteos. La presente investigación evaluó el efecto a 63 °C 30 min-1 73 15 seg-1 las concentraciones DDT, HCH sus metabolitos bovin...

The studies on binding of hexachlorocyclohexane (HCH) with carrier proteins were carried out to establish the role of proteins in the transport of insecticides in insects. Sephadex G-200 column chromatography resolved haemolymph of adult male desert locust, Schistocerca gregaria into three major protein peaks. There was significant binding of gamma-HCH with first protein peak (F1). Two classes ...

Hexachlorocyclohexanes (HCHs) were determined simultaneously in air and seawater during two cruises across the Atlantic Ocean between the Arctic Ocean (Ny-Alesund/ Svalbard, 79 degrees N; 12 degrees E) and the Antarctic Continent (Neumayer Station/ Ekstroem Ice Shelf, 70 degrees S; 8.2 degrees W) in 1999/ 2000. The concentrations of alpha-HCH and gamma-HCH in air and surface waters of the Arcti...

Here, we report the draft genome sequence (4.2 Mb) of Sphingobium quisquiliarum strain P25(T), a natural lin (genes involved in degradation of hexachlorocyclohexane [HCH] isomers) variant genotype, isolated from a heavily contaminated (450 mg HCH/g of soil) HCH dumpsite.

This study explores long-term environmental fate of α-HCH in China from 1952 to 2007 using ChnGPERM (Chinese Gridded Pesticide Emission and Residue Model). The model captures well the temporal and spatial variations of α-HCH concentration in Chinese soils by comparing with a number of measured data across China in different periods. The results demonstrate α-HCH grasshopping effect in Eastern C...

The involvement of phospholipase A2 (PLA2) and fatty acid release in the regulation of sodium-dependent high-affinity choline uptake in rat brain was assessed in vitro through the use of the specific binding of 3H-hemicholinium-3 (3H-HCh-3). Addition of arachidonic acid and other unsaturated fatty acids to rat striatal membranes in vitro resulted in a dose-dependent, temperature-independent act...

Data on pesticide body load in the south China region are scarce. Here, we report the concentrations of 24 persistent organic pollutants (POPs), in 10 pools of human milk samples, collected at 2-6weeks postpartum from 238 primiparous women living in Hong Kong and south China, who participated in the 2002-2003 WHO exposure study. Residues were determined by gas chromatography with electron captu...
