“…Though endosulfan is less soluble in water, the concentrations of endosulfan and its derivatives were high in ground water samples, accidental spills, spray drift, soil texture and run-in plays a vital role in endosulfan contamination. The higher concentration of the residues of HCH isomers recorded showed their greater solubility and leaching behaviour (Pillai, 1986;Mohapatra et al, 1995). The water samples collected from wetland system, Kerala, showed high concentration of HCH from 0.001 to 0.003 ppm (Agnihotri et al, 1996;Krishnan et al, 2001).…”

Modern agriculture practices reveal an increase in use of pesticides and fertilizers to meet the food demand of increasing population which results in contamination of the environment. In India crop production increased to 100% but the cropping area has increased marginally by 20%. Pesticides have played a major role in achieving the maximum crop production, but maximum usage and accumulation of pesticide residues was highly detrimental to aquatic and other ecosystem. The present study was chosen to know the level of organochlorines contamination in ground water of Thiruvallur district, Tamil Nadu, India. The samples were highly contaminated with DDT, HCH, endosulfan and their derivatives. Among the HCH derivatives, Gamma HCH residues was found maximum of 9.8 microg/l in Arumbakkam open wells. Concentrations of pp-DDT and op-DDT were 14.3 microg/l and 0.8 microg/l. The maximum residue (15.9 microg/l) of endosulfan sulfate was recorded in Kandigai village bore well. The study showed that the ground water samples were highly contaminated with organochlorine residues.

“…The agricultural use of lindane is diminishing, but no authentic data is available on present level of production. Higher incidence of lindane residue from the groundwater has been reported from the upper part of the Ganga basin [2,7,9]. Heptachlor has been detected rarely, indicating its limited application.…”

“…Studies on OCPs in the ground and surface waters of the alluvial plain of upper-and mid-Ganga basin though available [2,[6][7][8][9][10], little is known from the delta region specially in and around Kolkata, a large metropolis, known for numerous manufacturing industries, and a hinterland for paddy and cash crop cultivation in the Eastern India. The present investigation aims to make a quantitative evaluation of the anionic surfactants and OCP residues in surface water and groundwater sources, viz., the river Hugli and its tributary, ponds, lakes, dug wells, hand pumps and bore wells, from Kolkata urban and its surrounding areas.…”

An assessment on the concentration of surfactants and pesticides of chlorinated hydrocarbon group in surface and groundwater, is made from Greater Kolkata located in the Western Ganga Delta, one of the largest urban agglomerate in Asia. Concentration of both anionic synthetic detergents and organochlorine pesticide residues analysed from 54 and 19 sampling stations covering groundwater and surface water sources respectively, are generally found to be within the tolerance limit for human consumption. The concentration of synthetic detergent ranges from 0.084 to 0.425mg/l. Residues of organochlorine pesticides are analysed from different sources like tanks, lakes, rivers and groundwater. Lindane (0.01-0.43µg/l) and DDT (0.03-0.65 µg/l) are the most widely detected pesticide residues. Howerer, the two have not exceeded the limits for drinking anywhere. High value of aldrin and dieldrin (0.9µg/l) is obtained in the river Hugli at Barakpur-Seoraphuli, 20 km north of Kolkata. Likewise high value of Heptachloreis detected in a canal water sample at Palta (0.05 µg/l), a suburban area. Seasonally, the pesticide concentration in surface water is maximum during winter due to their higher application and minimum during monsoon. In groundwater, however, this relationship is reverse due to higher infiltration of surface water during monsoon.

“…Beta-HCH had the lowest value, indicating accumulation of this isomer in the environment possibly because of its stability and resistance to microbial degradation [29]. In another survey in 1991-1992, Mohapatra et al [30] found residues of HCH in the ground water near Farrukhabad in the vicinity of the Ganga river in Northern India. Alpha-HCH was the predominant isomer, followed by the gamma and beta isomers [30].…”

Genetic manipulations of microorganisms for the degradation of hexachlorocyclohexane

Hexachlorocyclohexane (HCH) is an organochlorine insecticide which has been banned in technologically advanced countries. However, it is still in use in tropical countries for mosquito control and thus new areas continue to be contaminated. Anaerobic degradation of HCH isomers have been well documented but until recently there have been only a few reports on aerobic microbial degradation of HCH isomers. The isolation of these microbes made it possible to design experiments for the cloning of the catabolic genes responsible for degradation. We review the microbial degradation of HCH isomers coupled with the genetic manipulations of the catabolic genes. The first part discusses the persistence of residues in the environment and microbial degradation while the second part gives an account of the genetic manipulations of catabolic genes inw)lved in the degradation.
