Department of Biochemistry, University College of Medical Sciences, Dilshad Garden, Delhi, 110 095, India.

Humans are exposed to various environmental chemicals such as organochlorine pesticide residues, heavy metals, polychlorinatedbiphenyls (PCBs) etc. There is paucity of data regarding the present blood levels of organochlorine residues in North Indian population with reference to reproductive health. The present study was designed to analyze the levels of organochlorine pesticide residues in maternal and cord blood samples of normal healthy women with full term pregnancy to gain insight into the current status of pesticide burden in newborns.

Evaluation of the concentration of HCH, DDT, HCB, PCB and PAH in the sediments along the lower stretch of Hugli estuary, West Bengal, northeast India.

Environ Int 2005 May 19;31(4):523-34. Epub 2004 Nov 19.

Water Research Institute-CNR, 25, Mornera Street, Brugheno 20047, Milan, Italy.

Detailed analyses of persistent organic pollutants (POPs) such as hexachlorocyclohexane (HCH) isomers (HCHs), dichlorodiphenyltrichloro ethane (DDT) and its metabolites (DDTs), hexachlorobenzene (HCB) and congeners of polychlorinated biphenyls (PCBs) and polycyclic aromatic hydrocarbons (PAHs) in surface sediments from the coastal estuarine environment of West Bengal, northeast India allowed the evaluation of the contamination status, distribution and possible pollution sources. HCH, DDT, HCB, PCB and PAH were identified compounds in all the samples, whereas the concentrations of chlorinated pesticides (trans-eptachlorepoxide, dieldrin, endrin, metaoxychlor and mirex) were below the detection limits and were not of great concern. The pesticides did demonstrate markedly different distributions reflecting different agricultural and domestic usage in the region. Read More

Correlation of chlorinated pesticides concentration in semen with seminal vesicle and prostatic markers.

Reprod Toxicol 2004 Dec;19(2):209-14

Industrial Toxicology Research Centre, Post Box no. 80, M.G. Marg, Lucknow 226001, India.

Semen samples of fertile and infertile men were analysed by gas liquid chromatography (GLC) for the presence of dichlorodiphenyltrichloroethane (DDT) and its metabolites (1,1-dichloro-2,2-bis(p-chlorophenyl) ethylene) (pp'-DDE); (1,1,1-trichloro-2,2-bis(p-chlorophenyl ethane) (pp'-DDT); (1,1-dichloro-2,2 bis(p-chlorophenyl) ethane) (pp'-DDD); (1,1,1-trichloro-2-(o-chlorophenyl)-2-(p-chlorophenyl) ethane) (op'-DDT), hexachlorocyclohexane (HCH) and its isomers alpha (alpha), beta (beta), gamma (gamma), delta (delta) and aldrin. The biochemical analysis of seminal vesicle and prostatic marker was done by spectrophotometer. The concentrations of alpha-, beta-, gamma-HCH, pp'-DDE and pp'-DDD were higher in the semen of infertile than in that of fertile men. Read More

Organochlorine pesticide residues in sediments of a tropical mangrove estuary, India: implications for monitoring.

Environ Int 2003 Aug;29(5):587-92

Department of Metallurgical Engineering, Jadavpur University, 700032 Calcutta, India.

The paper examines the concentrations of isomers of hexachlorocyclohexane (HCHs), dichlorodiphenyl trichloroethane and its metabolites (DDTs), alpha-endosulfan and endosulfan sulfate in surface sediment samples collected from the mouth of Hugli estuary in the vicinity of Sundarban mangrove environment, eastern part of India. An overall pattern of accumulation of these pesticides was in the order of: SigmaHCH>endosulfan sulfate>SigmaDDT>alpha-endosulfan. The concentration of these compounds was quite low. Read More

Distribution, fate and effects of pesticide residues in tropical coastal lagoons of northwestern Mexico.

Environ Technol 2002 Nov;23(11):1257-70

International Atomic Energy Agency, Marine Environment Laboratory, BP 800, MC98012 Monaco.

Analyses of pesticide residues in sediments, water and biota of the Altata-Ensenada del Pabellon coastal lagoon system in Sinaloa, Mexico, showed the presence of organochlorine and organophosphorus compounds. For all the compounds analysed, concentrations in sediments were higher near the points of water discharge from ponds and drainage from the agricultural area. Among the organochlorines, total DDTs displayed the largest sedimentary reservoir, followed by total endosulfans and chlorpyrifos. Read More

Environment Canada, National Water Research Institute, Canada Centre for Inland Waters, Burlington, Ont.

During August-September 1993, a joint Russian-United States expedition to the Bering and Chukchi Seas took place. Surface water samples were collected from 21 sites and separated into dissolved (duplicates) and suspended solids; 19 sediment and 6 air samples were also collected. These samples were analysed for 19 organochlorine pesticides, 11 chlorobenzenes and 113 PCB congeners. Read More

Monitoring of organochlorine and organophosphorus pesticides in the water of the Reconquista River (Buenos Aires, Argentina).

Water Res 2001 Oct;35(14):3457-61

Department of Basic Sciences, National University of Luján, Argentina.

The Reconquista river is a typical example of the adverse impact of human activity on a watercourse. Approximately 10% of the population of the country is settled on its basin and it receives wastewater discharges from residences and industries. This paper describes the results of the first systematic data for measurement of pesticides in surface water of the river, based on a monthly monitoring program over two-year span. Read More

Organochlorine pesticide residues in human fat in the United Kingdom 1976-7.

Br Med J (Clin Res Ed) 1981 Nov;283(6304):1425-8

Between May 1976 and August 1977 samples of human body fat were taken during routine necropsies in the United Kingdom on 236 subjects aged over 5 years and four infants aged under 4 months. Comparison with results from earlier studies showed a further decline in residues of pp'-dichlorodiphenyltrichloroethane (pp'-DDT) and dieldrin (HEOD) and increased amounts of hexachlorobenzene residues; concentrations of other compounds were similar to those observed in the studies carried out in 1963-4, 1965-7, and 1969-71. Comparison of the data with those from other countries, showed that the concentrations of organochlorine pesticide residues and polychlorobiphenyls in human fat samples from residents of the United Kingdom remain among the lowest in Europe and, indeed, the world.
