“…To date some researchers have also published some reviews as well as book chapters in pesticide analysis in water and food by using extraction methods coupled with mass spectrometric techniques [9][10][11][12][13][14][15]. These monographs were mainly highlighted the types of extraction methods, extraction-and chromatographic -techniques coupled with mass spectrometric techniques for the analysis of multi-residues pesticides in water, soil and food samples.…”

• Insecticides These are helpful to destroy insects Stomach poisons and contact poison .• Fungicides These are toxic to fungi and help to prevent plant diseases.• Herbicides These are helpful to kill weeds and other unwanted vegetation.• Others These includes rodenticides against rats, mice, grass hoppers etc., molluscicides against snails and nematicides control microscopic worms . Comprising over % of the Earth s surface, water is undoubtedly the most precious natural resource that exists on our planet. Without the seemingly invaluable compound comprised of hydrogen and oxygen, life on Earth would be non-existent it is essential for everything on our planet to grow and prosper. "lthough we as humans recognize this fact, we disregard it by polluting our rivers, lakes, and oceans. Subsequently, we are slowly but surely harming our planet to the point where organisms are dying at a very alarming rate. In addition to innocent organisms dying off, the drinking water has become greatly affected as is ability to use water for recreational purposes. In order to combat water pollution, we must understand the problems and become part of finding the solution.Recent Developments on Mass Spectrometry for the Analysis of Pesticides in Wastewater http://dx

“…Their metabolites are still present in the environs owing to their persistence, and are more harmful than their parent compounds. The toxicity, bioaccumulation and longer half-lives of the compounds present a high level of risk to the environment [4][5]. Organochlorine pesticides (OCPs) move in the environment through non-point sources such as agricultural runoff and vapourization following their field application.…”

“…A study from the Jukskei River catchment area in Gauteng, South Africa showed a significant high level concentration of OCPs in all the sampling points [8][9]. There were also some studies monitoring OCPs in sewage sludge in Europe [4,10]. The European Union has developed the draft of a "working document on sludge" to promote the use of sewage sludge in agriculture with limit values set for several heavy metals and some organic compounds, including seven PCB congeners (maximum limit of 800 ng/g).…”

The purpose of this study was to determine the concentrations of organochlorine pesticides (OCPs) in sewage sludge from three wastewater treatment plants (WWTPs), with a view to study their contribution to the environmental pollution of the Amathole District in Eastern Cape, South Africa. Analyses were performed by gas chromatography joined with micro electron capture detector (µECD). The limits of detection (LODs) of the tested congeners varied from 0.04 ng/g α-Lindane (α-BHC) to 0.49 ng/g (endosulfan sulfate), and the limits of quantification ranged from 0.22 ng/g (aldrin) to 2.17 ng/g δ-lindane (δ-BHC). Total concentrations of the 17 congeners for different seasons in the sludge ranged from 191 to 947 ng/g dw. For the six predominant congeners, the total highest concentration levels were found in this order dichlorodiphenyl trichloroethane (DDT), dichlorodiphenyl dichloroethane (DDD), α-BHC, γ-BHC, aldrin and endosulphate 1, and with values of 1512, 1330, 1095, 998, 994 and 547 ng/g respectively. For this result the contamination levels of some congeners for South African sludge can be categorized as high compared with European countries, but moderate to lower compared to other countries worldwide. Some congener (α-BHC, γ-BHC, aldrin, endosulphate 1, DDD and DDT) contents in the samples exceeded limits set by the European Commission for 1000 ng/g set for Σ DDT and 500 ng/g for other pesticide use of sludge in agriculture.

“…These OCPs being persistent organic pollutants and their metabolites are still present in the environments which are having mutagenic and carcinogenic effects. 1 Endosulfan (6,7,8,9,10,10-hexachloro-1,5,5a,6,9,9ahexahydro-6,9-methano-2,4,3-benzodio-3-oxide) is first generation Organochlorine pesticide introduced in 1950's and approved for use in 1954 in USA. It exists in two isomers as a-Endosulfan or Endosulfan (I) and b-Endosulfan or Endosulfan (II) in the ratio 7:3 having almost similar insecticidal activities, but have significant differences with respect to…”

Aerial application of persistent, bioaccumulative organochlorine pesticide endosulfan on cashew plantations to protect it from mosquito bug has led to contamination of soil and water environments in several parts of South Canara region, India. Endosulfan and its toxic residues like endosulfan sulfate are posing several threats to non-target organisms including humans. Biotransformation of toxic compounds using indigenous microbial strains is considered as safe and cost effective technique in bioremediation. In the present work, the bacterial strain designated as ES-1, has been isolated from the soil by enrichment method. The bacterial strain was found to mineralize endosulfan ˃99% of 100 mg/l completely biotically after 14 days of incubation by forming unknown polar metabolites.Whereas, abiotic degradation resulted in formation of a toxic compound, endosulfan sulfate. Based on 16s rDNA sequence analysis, the strain ES-1 showed 99% similarity to Bacillus sp. The results from the work suggest that, this bacterial strain could be employed for remediation of endosulfan contaminated environments.
