The levels of dichlorodiphenyltrichloroethane (DDT), dichlorodiphenyldichloroethylene (DDE), endosulfan, endosulfan sulfate, carbofuran, and cartap which were estimated in the flesh of Catla catla sampled from ten sites of Ravi River between its stretches from Shahdara to Head Balloki were studied to know the level of contamination of the selected pesticides by GC-ECD method. All fish samples w...

The increasing knowledge of the reproductive toxicity of environmental chemicals has raised public concern as to whether the current use of pesticides could adversely affect human reproduction. Among pesticides and their related chemicals, organochlorine insecticides have so far drawn the primary attention. Endosulfan is widely used pesticide due to its quick effect on insects. Endosulfan formu...

In the present study, we determined levels of chlorinated pesticide residues in surface water samples collected from Charsadda district (KPK, Pakistan). SPME-GC-ECD with COMBI PAL CTC autosampler was used for extraction and analysis 20 organochlorine pesticides samples. For maximum efficiency SPME procedure, several parameters were studied, including desorption time fiber, solution pH, agitatio...

Ecological risk assessment of pesticide residues is not only germane but critical in view their inherent health challenges and for informed decision-making process. This study was conducted to assess the levels contamination organochlorine water from Nwaniba River Uruan Local Government Area Akwa Ibom State. The analysis carried out using Gas Chromatography with electron capture detector (GC-EC...

In this study, the toxicity of endosulfan sulfate, the primary degradation product of the insecticide endosulfan, was determined in three life stages of the grass shrimp (Palaemonetes pugio). After 96 h exposure to endosulfan sulfate, the grass shrimp adult LC50 was 0.86 microg/L (95% CI 0.56-1.31), the grass shrimp larvae LC50 was 1.64 microg/L (95% CI 1.09-2.47) and the grass shrimp embryo LC...

OBJECTIVE Evaluate the ability of serum concentration of prostate specific antigen (PSA) between 2 cutting points to predict the existence of bone metastasis confirmed by bone scintigraphy in man with prostate cancer. MATERIALS AND METHODS Two hundred and fourteen consecutive patients with prostate cancer were evaluated during the present study in the period from 1998 to 2001. From all patien...

an investigation was conducted to study the larvicidal activity of teknar (san-402-i-bacillus thuringiensis, serotype h-14, sandoz, 600 itu/mg) on mosquitolarvaein kazeroun, fars province, southern iran. five experimental plots were selected randomly in a rice field and three concentrations of teknar: .0003, .0006 and .0012 cc/1 was used. maximum larval mortality usually occurred during the fir...

Organochlorine pesticides are one of the major groups of chemicals responsible for environmental contamination. Endosulfan a pesticide used mainly in cashew plantation is a highly toxic endocrine disrupter and a contact stomach poison. To study the endosulfan degrading microorganisms, 20 soil samples were collected from five different cashew plantations having a history of endosulfan applicatio...

Toxic effects of malathion and endosulfan to fertile chicken eggs were determined. Injection of 1.25, 2.5, 5.0 and 10.0 mg/egg of malathion into yolk sac of fertile eggs prior to incubation caused mortality of 10.0, 30.0, 83.33 and 93.33% respectively. Similar trend was observed with injection of endosulfan doses. Malathion and endosulfan at 1.25 mg/egg caused no pronounced LD50 increase in mor...
