The effect of oral administration of lindane (gamma-HCH) has been studied on the intestine in 10-day, 20-day and 100-day old rats. In 10 day-old suckling pups exposed to lindane, there was a significant decrease in the activities of sucrase (29%), lactase (20%) and that of alkaline phosphatase (24%) compared to control. Sialic acid content of the brush borders was significantly decreased (29%) ...

The organochlorine pesticides have been detected in the samples of sediment and muscle tissue of barbell (Barbus peloponnesius, Valenciennes, (1842); Barbus macedonicus, Karaman (1924), collected from the three natural lake ecosystems in the Republic of Macedonia, i.e. Lake Ohrid, Lake Prespa and Lake Dojran, in the period from 2004 to 2006. Special attention has been paid to the presence of th...

A subcritical water degradation and extraction method was developed to remediate environmental soils contaminated by highly recalcitrant organochlorine pollutants. Hydrogen peroxide used effectively decompose pollutants under conditions. As a optimization study, the static wet oxidation of chlorophenols first performed in with without added hydrogen peroxide. Complete achieved using an oxidant,...

Abstract Honey is a suitable matrix for the evaluation of environmental contaminants including organochlorine insecticides. The present study was conducted to evaluate residues fifteen insecticides in honey samples unifloral and multifloral origins from Dir, Pakistan. (5 g each) were extracted with GC grade organic solvents then subjected Rotary Evaporator till dryness. extracts mixed n-Hexane ...

Title:Potential effects of polychlorinated biphenyls (PCBs) and selected organochlorine pesticides (OCPs) on immune cells and blood biochemistry measures (NHANES 2003-2004)

organochlorine pesticides are as environmental pollutants which have a high half-life and transmit from food chain to human and cause side effects such as mutations in different genes and finally cancer. in this research, after sampling and quantitative and qualitative of organochlorine residue, biodegradation of alpha, beta and gamma hexachlorobenzene (linden), ddt, aldrin, dieldrin, endosulfa...

the aim of this study was to survey levels of polychlorinated biphenyls (pcbs), polychlorinated dibenzofurans (pcdfs), and polychlorinated dibenzo-p-dioxins (pcdds) in white mullet (mugil curema), common snook (centropomus undecimalis), and acoupa weakfish (cynoscion acoupa), collected at sepetiba bay, rio de janeiro, brazil, march-august 2013. pcbs and pcdd/fs were determined by high resolutio...
