A field study was conducted in the Taihu Lake region, China in 2004 to reveal the organochlorine pesticide concentrations in soils after the ban of these substances in the year 1983. Thirteen organochlorine pesticides (OCPs) were analyzed in soils from paddy field, tree land and fallow land. Total organochlorine pesticide residues were higher in agricultural soils than in uncultivated fallow la...

The widespread use of pesticides in agriculture during the last several decades has contaminated soils and different Critical Zone (CZ) compartments, defined as area extended from top vegetation canopy to groundwater table, it integrates interactions atmosphere, lithosphere, biosphere, hydrosphere. However, long-term fate, storage, transfer dynamics persistent CZ a changing world remain poorly ...

A comprehensive evaluation of the residual levels of Organochlorine insecticides (OCIs) in the sediment cores of Cochin Estuarine System (CES) is highlighted in this research article. It assessed the distribution pattern and impact of these xenobiotics in this environmental niche. Fifteen persistent organochlorine compounds (OCs) were quantitatively analysed in the six sediment core samples col...

Changes in biochemical status of nerve terminals in the corpus striatum, one of the primary brain regions affected in Parkinson's disease, were studied in groups of C57BL/6 mice treated by ip injection three times over a 2-week period with 3--100 mg/kg heptachlor. On average, the maximal rate of striatal dopamine uptake increased > 2-fold in mice treated at doses of 6 mg/kg heptachlor and 1.7-f...

Management of cocoa plantation field relied on the use of pesticides over the years; hence, the fate of such chemicals is one of the most debated issues among the stakeholders. Young and old cocoa plantation fields from 4 major cocoa producing States in Nigeria were selected as the study area. Eight composites soil samples collected from 3 portions of 6 transect measured area (100 x 50m) of the...

A prospective birth cohort of 1022 participants was established in the Faroe Islands over a 21-month period during 1986-1987. We collected questionnaire data on potential persistent organic pollutant (POP) concentration predictors, such as duration of breastfeeding and blubber consumption. To assess the participants' exposure from in utero to 14 years of age to polychlorinated biphenyls (PCBs) ...

Organochlorine pesticides such as DDT were long ago banned in America and Europe but due to their persistence their metabolites are still detected in the environment. In Greece, organochlorine insecticides such as DDT were extensively used before 1972 (Albanis et al. 1994). Coastal wetlands, which are widespread in Greece, are areas where pesticides from the agricultural activities of extensive...

The utilization of organochlorine pesticides for pest control chemical has been of great interest on residue contamination from biological organisms in the environment. Green mussel (Perna viridis) samples were monitored as bioindicators for assessment of the water quality in coastal waters along the Gulf of Thailand. Thirty-six samples were collected from 12 stations during 1997-1999 and analy...
