Abstract—In the present study, presence of endosulfan, imidacloprid, carbendazim, in the soil /vegetables/cereals and water samples was observed in agriculture fields of Uttarakhand. In view of biodegradation of these pesticides, 9 bacterial isolates were recovered from the soil samples of the fields which tolerated endosulfan, imidacloprid, carbendazim from 100 to 200 μg/ml. Three bacterial co...

The purpose of this study was to investigate the molecular mechanism underlying oxidative and inflammatory neuronal cell death induced by endosulfan, a pesticide belonging to the chemical family of organochlorines. The cortical and hippocampal tissues derived from Sprague-Dawley (SD) rats treated with endosulfan exhibited increased intracellular accumulation of reactive oxygen species and oxida...

In the present study, endosulfan degrading capability of four bacterial monocultures (RCE-2, GCE-4, GCE-5 and JCE-4) and two bacterial mixed-cultures (GCE345 and GCC134) was investigated in terms of treatment duration and culture volume, using soil slurry medium. Among the bacterial mono-cultures, JCE-4 was found to be most efficient with 16, 33, 60 and 65% of endosulfan (α + β-isomers) degrada...

Organochlorine pesticides (OCPs) such as DDT and DDE have been detected in the surface 0.2m of Vertisols in the lower Namoi Valley of north western New South Wales, Australia even though they have not been applied to crops since 1982. However, their presence in the deeper soil horizons has not been investigated. The objective of this study was to determine if OCPs were present to a depth of 1.2...

Four commonly applied extraction techniques for organochlorine pesticides, microwave-assisted extraction (MAE), accelerated solvent extraction (ASE), quick, easy, cheap, effective, rugged, and safe (QuEChERS) extraction and ultrasonic solvent extraction, were applied on soil samples in order to evaluate their performances. The extracts were analyzed by GC-ECD and confirmed by GC-MS/MS. The MAE ...

Individuals, typically, are exposed to mixtures of environmental xenobiotics affecting multiple organs and acting through different xenosensors and pathways in species and cell-type specific manners. 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) and α-endosulfan are Persistent Organic Pollutants (POPs) and endocrine disruptors which act through different xenosensors and accumulate in the liver. Ou...

The rapid increase in the world population causes different problems such as nutrition and shelter. In this case, people brutally destroy arable land to shelter, concretization is rapidly spreading. addition, it necessary amount of products be taken from limited agricultural areas for food needs increasing population. decrease appears a factor that reduces product unit area. weeds especially in...

Water, sediment and fish samples of East Kolkata wetland were monitored using GC-ECD for residues of organochlorinated (OC) and synthetic pyrethroid (SP) pesticides. Among the OCs, HCH (α, β,  and ) were detected in water (0.02 – 0.1 μg/L) and in Cyprinus carpio (1.23-8.9 μg/kg) but none in sediments or in Oreochromis mossambicus. In Cirrhinus mrigala only α-HCH was recorded. In case of DDTs,...

Extensive applications of organochlorine pesticides like endosulfan have led to the contamination of soil and environments. Five different bacteria were isolated from cockroaches living in pesticide contaminated environments. According to morphological, physiological, biochemical properties, and total cellular fatty acid profile by Fatty Acid Methyl Esters (FAMEs), the isolates were identified ...

Contamination in milk is more critical as compared to other foods as milk is first diet given to children before they are able to digest solid food. Children have low immunity to combat diseases, so their exposure to pesticide residues is of extreme concern. Lactating animals can be exposed to pesticide residues in several ways such as contaminated feed, contaminated water or direct contact wit...
