A mixed bacterial culture consisted of Staphylococcus sp., Bacillus circulans-I and -II has been enriched from contaminated soil collected from the vicinity of an endosulfan processing industry. The degradation of endosulfan by mixed bacterial culture was studied in aerobic and facultative anaerobic conditions via batch experiments with an initial endosulfan concentration of 50mg/L. After 3 wee...

BACKGROUND The organochlorine pesticides (OCPs) are among the most commonly used in water streams around the world. Most of these contaminants are highly hydrophobic and persist in sediments of rivers and lakes. Studies have suggested that OCPs may affect the normal function of the human and wildlife endocrine systems. OBJECTIVES The aim of this study is to determine the concentrations of sel...

Adsorption and desorption characteristics of endosulfan in four Indian soils were studied extensively. The soils used were clayey soil (CL--lean clay with sand), red soil (GM--silty gravel with sand), sandy soil (SM--silty sand with gravel) and composted soil (PT--peat) as per ASTM (American Society for Testing and Materials) standards. Adsorption and desorption rates were calculated from kinet...

Persistent organic pollutants (POPs) have been associated with a wide range of adverse health effects. Our case-control study was performed to explore the association between placental levels of selected POPs and risks for neural tube defects (NTDs) in a Chinese population with a high prevalence of NTDs. Cases included 80 fetuses or newborns with NTDs, whereas the controls were 50 healthy, nonm...

Enzyme-linked immunosorbent assay (ELISA) for detection of endosulfan was developed using antibodies raised against endosulfan. The competitive assay formatted was specific to endosulfan with a limit of detection of 1ng. The application and efficiency of the assay were tested for the detection of residues in different food samples. With an efficient extraction method, the recoveries ranged from...

Th e persistence of endosulfan and intermediate metabolite endosulfan sulfate in the environment and their toxic eff ects on biota necessitate their removal. Th is study investigated the bioaugmentation of endosulfan-contaminated soil by fungal inoculant Aspergillus niger ARIFCC 1053. Th e infl uence of bioaugmentation by A. niger on endosulfancontaminated soil was evaluated with the help of ch...

OBJECTIVES Endosulfan is a lipophilic insecticide, which causes severe health issues due to its environmental stability, toxicity, and biological reservation in organisms. It is found in the atmosphere, soil, sediments, surface waters, rain, and food in almost equal proportions. The aim of this study was to isolate and identify endosulfan-degrading bacteria from the Kor River and evaluate the p...

BACKGROUND The role of oxidative stress in endosulfan-induced reproductive toxicity has been implicated. This study was performed to evaluate the possible protective effect of vitamins E and C, against endosulfan-induced reproductive toxicity in rats. METHODS Fifty adult male Sprague-Dawley rats were randomly divided into five groups (n=10 each). The groups included a control receiving vehicl...

Aim: Endosulfan is an important toxic agent which generates free oxygen radicals in liver. In Çukurova region, some relation between the incidence of toxic injury to liver and widespread use of endosulfan has been suggested. Since endosulfan is a frequently used pesticide, it was planned to investigate whether endosulfan could do liver injury and increase lactic dehydrogenase in liver. Methods:...

The effects of pre-training and post-training administration of endosulfan on retention of a step-down passive avoidance task was studied in mice. Endosulfan at doses of 1.0 mg/kg(ip) and 2.0 mg/kg(ip) enhanced memory acquisition and retention. This effect of endosulfan was possibly mediated by interaction with cholinergic neurotransmission, as scopolamine (0.5 mg/kg, ip) significantly antagoni...
