anzali wetland is one of the most important aquatic ecosystems of iran located in south of the caspian sea. this wetland is a habitat for valuable fishes and aquatic animals which have an important role in life cycle of this ecosystem. agroup of the pollutants entering these wetlands is the persistent organic pollutants. this pollutants has a wide range of ingredients in the environment and are...

Cardiovascular disease is one of the most significant causes of mortality in humans and animals, and its etiology is usually unknown. The aim of this study was to investigate the cardiac pathology of endosulfan toxicity and the protective effect of vitamin C in rabbits. Twenty-four rabbits were divided into 4 groups: (1) the END group was given a daily sublethal dose of endosulfan in corn oil b...

This paper documents levels of organochlorine pesticides (OCs) in coastal surface sediments from selected reference sites on the northern Atlantic Spanish coast. One hundred eight samples covering three estuaries in the Cantabrian Coast were sampled in 2006 and analyzed in the finer fraction (<63 μm) for 19 OCs by gas chromatography with electron capture detector after confirmation by mass spec...

Endosulfan has an organochlorine pesticide. It may impair the normal embryonic development and disrupt normal reproductive functions in adulthood. Experiments were conducted on swiss albino mice (Mus musculus) under controlled physical conditions of temperature, ventilation and cleaning. The experiment was conducted in polypropylene cages. Cages of two sizes, (a) small cage=26×19×13 cm and (b) ...

Aquatic birds are often used as a health indicator of the marine ecosystem. African penguins living in the zoo make good research material as they form a link between the marine and the terrestrial ecosystem in terms of xenobiotic circulation. Tests were performed on whole herring-the food of the penguins-as well as on bird muscle, liver, brain, eggs, feathers and guano in order to determine to...

The effects of insecticides (endosulfan, HCH) and heavy metals (copper and zinc) were studied on survival and duration of the moult cycle of larvae and megalopa of a common mangrove crab, Macrophthalmus erato, that inhabits Pitchavaram mangroves, southeast coast of India. In chronic toxicity test, percentage of survival from hatchling to megalopa stage at different concentrations of endosulfan ...

A study of endosulfan excretion in human urine was carried out by using an agricultural worker involved with spraying, wearing protective overall, gloves and breathing mask. The urine samples were extracted with Solid Phase Extraction (SPE) cartridges and the compounds were separated and detected using Gas Chromatography-Tandem Mass Spectrometry (GC-MS/MS) due to their high sensitivity and sele...

Oxidative stress has been implicated in pesticide-induced neurotoxicity, based on its role in the cascade of biochemical changes that lead to dopaminergic neuronal cell death. We have, therefore, examined the role of oxidative stress caused by the pesticides endosulfan and zineb in human neuroblastoma cells (SH-SY5Y) in culture. Upon treatment with 50-200 μM concentrations of either of these pe...

This paper investigates the potential use of composted cotton gin trash (CCGT) as a pesticide sorption medium in remediation of contaminated tailwater. CCGT was found to contain a large organic matter fraction (25.22%). Sorption of endosulfan sulfate and diuron, using the batch equilibrium method, was rapid but not limited for the range of applied concentrations, with diuron failing to reach eq...

Endosulfan, a chlorinated cyclodiene insecticide, was administered orally at 1.5, 3, 6, and 9 mg/kg per day to normal hemicastrated virgin mice for 15 consecutive days to examine the effect on ovarian function. Sham-operated and hemicastrated control mice were administered a similar volume of olive oil. The vaginal smear and body weight of the mice were recorded daily and mice were sacrificed o...
