An extraction method based on matrix solid phase dispersion (MSPD) and high performance liquid chromatography with UV detection for quantification of two widely used pesticides (Malathion and α-Endosulfan) in Khazar rice from north of Iran were investigated. The ratio of solid phase (adsorbent) to sample, types of eluting solvent and its volume were optimized to achieve the highest recoveries f...

Atmospheric concentrations of organochlorine pesticides (OCPs) have been measured for the first time at Station Nord, North-East Greenland, from 2008 to 2010. The data obtained are reported here. Hexachlorobenzene (HCB), endosulfan I and hexachlorocyclohexanes (HCHs) were the predominant compounds detected in the atmosphere, followed by p,p'-DDE and dieldrin. Chlordane isomers and related compo...

Pesticide degradation is the challenges of the day were safe, rapid and economically efficient methods are searched. In the process present paper made an attempt to isolate secondary metabolites from Cipadessa baccifera and degrade endosulfan at two different concentrations. Significant degradation was obtained with secondary metabolites with P value = <0.0001 for both 1000 and 2000 μg/ml conce...

Endosulfan exposure (8 and 16 mg/kg) to rats significantly decreased the activities of superoxide dismutase and catalase, level of reduced glutathione and increased lipid peroxidation. The primary and secondary antiSRBC antibody titers, plaque forming cells counts and delayed hypersensivity reaction, and the TH1 or TH2 cytokines levels were significantly suppressed in a dose dependent manner. L...

OBJECTIVES Pancreas pathology in subacute endosulfan toxicity and the effect of vitamin C in rabbits were studied. METHODS : Twenty-four rabbits in 4 groups were used. The rabbits in group END were given a daily sublethal dose (1 mg/kg of body weight) of endosulfan in corn oil by oral gavage for 6 weeks. Group END+C received the same dose of endosulfan and also vitamin C (20 mg/kg) every othe...

The effect of soil properties like adsorption, desorption, movement and distribution of endosulfan (1, 2, 3, 4, 7, 7-hexachlorobicyclo (2, 2, 1)-2-heptene-5, 6-bisoxymethlene sulfite) in two tropical soils, sandy loam and sandy clay soil from Mysore, Karnataka state were studied respectively. The results indicated that soils with different physico-chemical properties have different effects on t...

AIM The present study was undertaken to estimate the current status of residues of organochlorine pesticides (OCPs), organophosphates (OPs) and synthetic pyrethroids (SPs) pesticides in human blood. MATERIALS AND METHODS Human blood samples were analyzed by gas chromatography and confirmed by gas chromatography-mass spectrometry in selective ion monitoring mode. RESULTS The gas chromatograp...

Global amphibian declines have many corroborative causes, and the use of pesticides in agriculture is a likely contributor. In places with high pesticide usage, such as Costa Rica, agrochemical pesticides may interact with other factors to contribute to rapid species losses. Classical ecotoxicological studies rarely address the effects of a pesticide in combination with other stressors. The pre...
