Monitoring of organochlorine and organophosphorus pesticide residues in water during different seasons of Tighra reservoir Gwalior, Madhya Pradesh, India.

摘要: Analysis of pesticides during different seasons for pesticidal contamination in water samples Tighra reservoir was carried out on gas chromatograph-electron capture detector with capillary columns following multiresidual analytical technique. Organochlorine pesticides, viz., hexachlorobenzene (HCB), alpha-benzene hexachloride (BHC), beta-BHC, γ-BHC, heptachlor, aldrin, alpha-endosulfan, beta-endosulfan, p,p-DDE, dieldrin, o,p-dichlorodiphenyldichloroethane (DDD), p,p-DDD, p,p-dichlorodiphenyltrichloroethane (DDT), and endrin, organophosphorus choloropyrifos, methyl parathion, diazion, dicholorovos, ethion, malathion, were detected seasons. However, the pesticide concentration varied at sites. The prominent reason is use (both organochlorine organophosphorus) agricultural fields near reservoir. On basis our observations, more extensive monitoring studies need to be out, covering all wetlands Madhya Pradesh enforce policies restricted application adjacent wetlands.
