Aim: To isolate bacteria capable of degrading endosulfan (ES) and the more toxic ES sulfate and to characterize their metabolites. Methods and Results: A Pseudomonas sp. strain IITR01 capable of degrading α‐ES and toxic ES sulfate was isolated using technical‐ES through enrichment culture techniques. No growth and no degradation were observed using β‐ES. Thin‐layer chromatography and gas chromatography‐mass spectrum analysis revealed the disappearance of both α‐ES and ES sulfate and the formation of hydroxylated products ES diol, ether and lactone. We show here for the first time the formation of aforementioned metabolites in contrast to ES hemisulfate yielded by an Arthrobacter sp. Metabolism of α‐ES and endosulfate was also observed using the crude cell extract of IITR01. The molecular mass of protein induced during the degradation of α‐ES and sulfate as substrate was found to be approximately 150 kDa as determined by sodium dodecyl sulfate–polyacrylamide gel electrophoresis (SDS–PAGE). Conclusion: We describe characterization of bacterium capable of degrading α‐ES and ES sulfate but not β‐ES. Genetic investigation suggests that a gene nonhomologous to the reported esd may be present in the strain IITR01. Significance and Impact of the Study: This study describes toxic ES degradation by a Pseudomonas species that may be utilized for the bioremediation of the industrial soils contaminated with ES residues.

“…ES has slowly leached from such contaminated sites to water sink over exceedingly long periods, and thus it has become a continuous source of contamination in various water supplies. The residues of ES have been reported from fish samples collected from various points of the Ganga river (Aktar et al. 2009).…”

“…Synthetic insecticides were also used to control adult mosquitoes by fogging [13]. The continuous use of synthetic insecticide such as malathion, DDT, HCH and deltamethrin for controlling mosquitoes has created diverse environmental problems such as toxicity to non target organisms [14], development of genetic resistance in mosquitoes [15], environment pollution [16] and their non degradable nature results in biomagnifications. Herein, the worldwide continuous efforts to eradicate and control this vector were found ineffective.…”

BackgroundIndiscriminate use of synthetic insecticides to eradicate mosquitoes has caused physiological resistance. Plants provide a reservoir of biochemical compounds; among these compounds some have inhibitory effect on mosquitoes. In the present study the larvicidal, adulticidal and genotoxic activity of essential oil of Psoralea corylifolia Linn. against Culex quinquefasciatus Say was explored.MethodsEssential oil was isolated from the seeds of P. corylifolia Linn. Larvicidal and adulticidal bioassay of Cx. quinquefasciatus was carried out by WHO method. Genotoxic activity of samples was determined by comet assay. Identification of different compounds was carried out by gas chromatography- mass spectrometry analysis.ResultsLC50 and LC90 values of essential oil were 63.38±6.30 and 99.02±16.63 ppm, respectively against Cx. quinquefasciatus larvae. The LD50 and LD90 values were 0.057±0.007 and 0.109±0.014 mg/cm2 respectively against adult Cx. quinquefasciatus,. Genotoxicity of adults was determined at 0.034 and 0.069 mg/cm2. The mean comet tail length was 6.2548±0.754 μm and 8.47±0.931 μm and the respective DNA damage was significant i.e. 6.713% and 8.864% in comparison to controls. GCMS analysis of essential oil revealed 20 compounds. The major eight compounds were caryophyllene oxide (40.79%), phenol,4-(3,7-dimethyl-3-ethenylocta-1,6-dienyl) (20.78%), caryophyllene (17.84%), α-humulene (2.15%), (+)- aromadendrene (1.57%), naphthalene, 1,2,3,4-tetra hydro-1,6-dimethyle-4-(1-methyl)-, (1S-cis) (1.53%), trans- caryophyllene (0.75%), and methyl hexadecanoate (0.67%).ConclusionEssential oil obtained from the seeds of P. corylifolia showed potent toxicity against larvae and adult Cx. quinquefasciatus. The present work revealed that the essential oil of P. corylifolia could be used as environmentally sound larvicidal and adulticidal agent for mosquito control.

“…Therefore, health risk assessment due to pesticidal residues has been conducted worldwide. [16][17][18] Significant level of residues of HCHs and DDTs has been found in the biotic [19][20][21][22] and abiotic [23][24][25][26][27][28] compartment in the past and also in the recent years in India. Although study on HCH and DDT residues in vegetables have been carried out in India 29-38 but, quantitative health risk from HCH and DDT in vegetables from India was rarely investigated.…”

Human health risk from hexachlorocyclohexane and dichlorodiphenyltrichloroethane pesticides, through consumption of vegetables: estimation of daily intake and hazard quotients

People are encouraged to consume more fresh vegetables due to the high nutritional value and fibre contents in vegetables. At the same time, due to pesticidal residue in vegetables, vegetable consumption is considered as an important route of pesticides uptake by human beings. Pesticides, particularly organochlorines such as Aldrin, heptachlor and isomers of dichlorodiphe - nyltrichloroethane (DDT) and hexachlorocyclohexane (HCH) are a major concern because of their persistence, bioaccumulation, toxicity, and long-range environmental transport ability. Hence information on such toxic contaminants in vegetables is very essential, due to human health concern. In order to assess the potential health risks associated with vegetable consumption due to pesticidal residues of DDT and HCH, sixty four samples of commonly available vegetables were collected from a local market in West Bengal, India and analysed for DDT and HCH. In this study, estimated average daily intake of HCHs and DDTs through vegetables was ranged between 5.0x10^–8–9.1x10^–6 mg kg^–1 day^–1 with an average value of 2.0x10^–6 mg kg^–1 day^–1. Human health risk was assessed in terms of incremental lifetime cancer risk and health hazard index was between 1.7x10^–8–8.8x10^–6 and 1.5x10^–7– 1.7x10^–2, respectively. Generated results were compared with maximum residual levels and reference values, were within acceptable limits and suggested no health risk to the human populations. Therefore, an extensive study on vegetables with the inclusion of other persistent organic pollutants and toxic metals should be carried out to know the overall scenario of contamination of vegetables
