Analysis of Residual Level of Organochlorine Pesticide in Some Food Items in Anambra State
Journal Title: Journal of Medical Science And clinical Research - Year 2015, Vol 3, Issue 1
Abstract
Organochlorine pesticide residueswere measured in guinea corn, maize, beans, bambara groundnut and millet. These cereals were bought from 5 markets in different locations of Anambra state, Nigeria .40g of each of the powdered cereals was used for the extraction process by the method of Carlo, et al.,(2009), while the products of extraction was analyzed using gas chromatography. The mean of the overall pesticides in μg/kg( with standard deviation) in the food samples were: Maize 0.0377 ( ±0.0041), Beans0.0359(± 0.0047), Bambara groundnut 0.0360 (±0.0039), Guinea corn0.0352(±0.0046), Millet0.0052(±0.0068). Our results revealed that foods from Onitsha generally showed the highest pesticide level. Among all the pesticides, aldrin was found to exhibit the highest concentration of the pesticides in the foods. It was observed that cereals from Anambra State were exposed to some levels of contamination of Organochlorine pesticides, although these levels may not be a serious health challenge to the public, hence there is need for a concerted effort towards continuous monitoring of these pesticide residues in our foods and environment. However, this research has opened avenues for other researchers in Anambra State and beyond to discover other frontiers towards the preservation of foods.
