India is the second largest producer of vegetables after China, and accounts for 13.4% of world production. Surveys carried out by institutions spread throughout the country indicate that 50-70% of vegetables are contaminated with insecticide residues. Rapid, inexpensive and sensitive methods such as pesticide finger printing technique and enzyme-linked immunosorbent assay developed at CFTRI, M...

Water samples were collected from Msimbazi and Kizinga rivers in Dar es Salaam and from the coastal marine environment receiving waters from these rivers during both the wet season and the dry season and analysed for various organochlorine pesticide residues using GC-ECD. The pesticides p,p’-DDE, p,p’-DDT, dieldrin and γ-HCH were the only organochlorines detected at significantly greater concen...

p,p'-dichlorodiphenyldichloroethylene (p, p'-DDE) and β-hexachlorocyclohexane (β-HCH) were two predominant organochlorine pesticides (OCPs) metabolites in human body associated with disorders of fatty acid metabolism. However, the underlying mechanisms have not been fully clarified. In this study, adult male C57BL/6 mice were exposed to low dose of p, p'-DDE and β-HCH for 8 wk. OCPs accumulatio...

Despite the fact that most persistent toxic substances have hardly been primarily emitted for several decades, their concentrations are only slowly decreasing in the global oceans. Surface seawater samples were collected along a 38°-24° N/28°-67° W transect in the subtropical North Atlantic Ocean. While the concentration levels of hexachlorobenzene (2.1-6.1 pg L-1), dichlorodiphenyltrichloroeth...

Organochlorine pesticides are used to control the mosquitoes and agricultural pests worldwide. These compounds were very popular and heavily used agriculture and public health due to cheap cost and versatile action against various pests. DDT (Dichlorodiphenyl trichloro ethane) and HCH (Hexachlorohexane) were the important organochlorine insecticides which were used for control of mosquitoes in ...

As a result of its unique location, Turkey receives air masses from Europe, Russia, Middle East, and Africa, making it an important place in terms long-range atmospheric transport (LRT) contaminants. Atmospheric levels 22 organochlorine pesticides (OCPs), 45 polychlorinated biphenyls (PCBs), 14 polybrominated diphenyl ethers (PBDEs) were measured two metropolitan cities, Istanbul Izmir, on week...

In Northern Benin, insecticides are used for cotton production. These can be easily transferred to water ponds close fields. To monitor levels in water, sediments and fish samples from ponds, a GC–MS analytical method was developed detect residues of endosulfan, DDT its parent compounds, isomers HCH, pyrethroids chlorpyrifos. addition, the influence storage conditions sample on pesticides deter...

The objective of the present study was to monitor the levels of organochlorine pesticides HCB, α-β-γ-HCH, pp'DDE, op'DDT and pp'DDT in 150 adipose tissue samples of Veracruz, Mexico inhabitants. In analyzed samples, the following pesticides were detected: p,p'-DDE in 100% of the samples at mean 1.643 mg/kg; p,p'-DDT in 99.3.% of the samples at mean 0.227 mg/kg; β-HCH in 97.3% of the samples at ...

This study investigated the compositions and distributions of pesticides buried at five sites in Tanzania. Samples were collected from various depths up to 220 cm. The analytes in samples were extracted by pressurized fluid extraction. Labelled internal standards were used for identification and quantification. Clean-up of extracts was conducted by using column chromatographic techniques. Deter...

The temporal distribution of organochlorine pesticides (OCPs) was examined in the (210)Pb dated sediment core from the Beibu Gulf, South China Sea. The total OCPs concentrations were in the range of 0.93-26.6 ng g(-1) dry weight. Dichlorodiphenyltrichloroethanes (DDTs) (0.17-24.8 ng g(-1)), Hexachlorocyclohexanes (HCHs) (0.04-0.51 ng g(-1)), Chlordane related compounds (CHLs) (0.22-1.72 ng g(-1...
