ABSTRACT

This is an experimental research study carried out at the laboratory of wholesale fruits and vegetable market, Attarya, Kailali, to analyze organophosphate and carbamate pesticide residue in vegetables grown and marketed in four different districts of far-west Nepal by Rapid Bioassay of Pesticide Residue. The main goal of this study is to determine the proportion of AChE inhibition in various vegetable commodities and to compare the pesticide residue. Seven different vegetables were collected purposively from four distinct areas in Nepal’s far west region. Each of the 28 vegetable samples was analyzed for both organophosphate and carbamate residues. The sample was extracted from each vegetable and examined through a spectrophotometer and the data are interpreted. The experiment’s findings suggest that the Beans from Kanchanpur had the highest OP (21.69 percent) while cucumber from Dadeldhura had the lowest (0.07 percent). The bitter gourd of Kailali had the greatest C (24.39 percent), while the bottle gourd of Doti had the lowest (0.49 percent). All 56 items examined in the Attariya market laboratory were found to have low pesticide residue, with less than 35%. However, the waiting period must be strictly adhered to.
