Abstract

 

The concentration level of organochlorine pesticides in the soil of Bathinda, Punjab was studied using Gas Chromatography equipped with 63Ni Electron-Capture Detector (GC-ECD). In February 2016, 19 soil samples were collected from different locations representing different land-use types of Bathinda i.e. agriculture, roadside, residence, commercial land, wasteland and industrial. Out of these land-use types studied, agricultural soil contributed maximum towards the OCP load followed by wasteland, residential, commercial, roadside and industrial sites. The study has shown the contamination of the soil of this region by all the nine pesticides viz. α-BHC, γ-BHC, Heptachlor, Endosulfan-I, Dieldrin, Endrin, 4,4’-DDD, 4,4’-DDT and Methoxychlor at all the sampling locations. Endosulfan was found to be the most abundant OCP followed by Heptachlor > 4,4’-DDT > Methoxychlor > α-BHC ≈ γ-BHC > Dieldrin > 4,4’DDT > Endrin. The total organochlorine pesticides level ranged from 34.09 ng/g to 1407.79 ng/g. Most of the OCPs found in this study have been officially banned, but they are still present in the soil of this region. The present study would serve as a baseline data for further analyzing the pesticide usage in this cotton belt of Punjab.
