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...

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...

AIM The present study was aimed to investigate the immunological competence of endosulfan insecticide after limited oral administration in White Leghorn layer chickens. MATERIALS AND METHODS A total of 20 White Leghorn birds were given endosulfan in drinking water at 30 ppm/bird/day (no observable effect level dose) for a period of 3-months. Immune competence status of layer birds and chicks ...

Male and female albino rats given different oral doses (0.75, 2.5, 5.0 and 0.25, 0.75, 1.5 mg/kg/D) of endosulfan respectively for a period of 30 days elicited signs of toxicity such as hyperexcitability, tremor, dyspnea and salivation for a brief period. At the tested dose levels, endosulfan produced no significant change in the organ body weight ratio, biochemical, histological, haematologica...

Background & Objective: Endosulfan is one of the strong insecticides used in agriculture. This toxin is absorbed by inhalation and skin. Endosulfan has side effects such as infertility in men. This study surveys the effect of vitamins E and C on  preventing the harmful effects of Endosulfan on spermatogenesis in adult male rats. Materials & Methods: Adult male rats (200-250 g) from Wistar...

Humans are exposed to distinct structural classes of insecticides with different neurotoxic modes of action. Because calcium homeostasis is essential for proper neuronal function and development, we investigated the effects of insecticides from different classes (pyrethroid: (α-)cypermethrin; organophosphate: chlorpyrifos; organochlorine: endosulfan; neonicotinoid: imidacloprid) and mixtures th...

Acute toxicity tests for the pesticides endosulfan and malathion on the larvae of Chironomus ramosus were conducted. Median Lethal Concentration (LC50) values of endosulfan were 0.55 x 10(-2), 0.16 x 10(-2), 0.089 x 10(-2) and 0.036 x 10(-2) ppb respectively, while those for malathion were 0.139 x 10(-2), 0.054 x 10(-2), 0.019 x 10(-2) and 0.0032 x 10(-2) ppb respectively, at 24, 48, 72 and 96 ...

Endosulfan, an organochlorine (OC) insecticide belonging to the cyclodiene group, is one of the most commonly used pesticides to control pests in vegetables, cotton and fruits. To evaluate the health risk due to the exposure to Endosulfan in the environment, a framework was developed by combining three sub – models: (1) the fugacity model which evaluates the dynamic performance of Endosulfan in...
