“…[37] DDT was recorded in Saudi Arabic groundwater at 1.07 × 10 5 ng L −1 in Gazan, while DDE at 5.6 × 10 3 ng L −1 in Wadi Al-Dawaser and 9 × 10 4 ng L −1 in Gazan. [38] Our results were also compared to those reported by Zhou et al [39] and DDE was found to dominate DDT family in surface water of Qiantang River. The observed concentrations of DDTs were the highest in summer-autumn period similar to ours; however, our concentrations are much higher.…”

This study reviews the detection of pesticides in different surface and groundwater samples collected from South Litani region in South Lebanon during 2012. These have been analyzed using an optimized and validated solid phase extraction method followed by gas chromatography coupled with mass spectrometry. Organochlorine and organophosphate pesticides were mostly noted at levels below the recommended value for individual pesticide in water except pirimiphosmethyl that was recorded at 300.87 ng L −1 in groundwater sample, designated for drinking water and collected in February. DDE concentration exceeded 100 ng L −1 in both surface and groundwater in October. The reported results represent the first Lebanese statistical data illustrating the quantification of pesticides in water over a period of time. More importantly, it draws attention to the need of pesticides' monitoring programs in the Lebanese water resources.

Sources, concentrations and risk factors of organochlorine pesticides in soil, water and sediment in the Yellow River estuary

The environmental occurrence, sources and risk factors of organochlorine pesticides (HCHs and DDTs) and their isomers or metabolites were studied using comprehensive surveys (including soil, surface water, groundwater and sediment sampling) conducted in the Yellow River Delta (YRD). HCHs and DDTs were all detected in multi environmental media. Compared with reported organochlorine pesticide values in China and abroad and with related environmental quality standards, the concentrations of HCHs and DDTs were generally at low levels in the YRD. Composition of OCPs (DDT metabolites and HCH isomers) showed that DDTs in the multiple environments of the YRD not only came from residues of dicofol but also from atmospheric deposition, while HCH pollution results from the historical usage of a mixture of technical HCH and lindane. Furthermore, the sum of Excess Lifetime Cancer Risk (∑ELCR) exposure to HCHs exceeded the generally acceptable risk level of 1.0E-06 recommended by the USEPA for carcinogenic chemicals.

“…HCH residues at many of the sites have percolated into the soil and thence contaminated groundwater (145). Residues of HCH isomers have now been reported for many countries in samples of air (76,79,138), water (8,71,139), soil (29,50,71,139,144), food commodities (7,17,175,184), milk (153,197), fish (44,87), and mammals (48) and even from human blood samples (15,169) and adipose tissue (14,73). Environmental residues from sites as remote from the major regions of production and use as the Arctic, Antarctic, and Pacific Ocean have been reported (63,185).…”

SUMMARY Lindane, the γ-isomer of hexachlorocyclohexane (HCH), is a potent insecticide. Purified lindane or unpurified mixtures of this and α-, β-, and δ-isomers of HCH were widely used as commercial insecticides in the last half of the 20th century. Large dumps of unused HCH isomers now constitute a major hazard because of their long residence times in soil and high nontarget toxicities. The major pathway for the aerobic degradation of HCH isomers in soil is the Lin pathway, and variants of this pathway will degrade all four of the HCH isomers although only slowly. Sequence differences in the primary LinA and LinB enzymes in the pathway play a key role in determining their ability to degrade the different isomers. LinA is a dehydrochlorinase, but little is known of its biochemistry. LinB is a hydrolytic dechlorinase that has been heterologously expressed and crystallized, and there is some understanding of the sequence-structure-function relationships underlying its substrate specificity and kinetics, although there are also some significant anomalies. The kinetics of some LinB variants are reported to be slow even for their preferred isomers. It is important to develop a better understanding of the biochemistries of the LinA and LinB variants and to use that knowledge to build better variants, because field trials of some bioremediation strategies based on the Lin pathway have yielded promising results but would not yet achieve economic levels of remediation.
