This study was aimed to determine the residual organochlorine presence in some staple foods; Yam (Dioscorea spp) and Bambara nut (Vigna subterranean) sold in Wukari markets. Samples were randomly collected from three major markets across the study areas. Representative samples were cleansed, dried, pulverized and sieved. Extractions were determined using standard analytical techniques while residual organochlorine pesticides were determined using GCMS. The detected organochlorine pesticide residues in yam were Dichlorodiphenyltrichloroethane (DDT), heptachlor, dieldrin, toxaphene and Dichlorodiphenyldichloroethane (DDE) while those detected in Bambara nut were 1, 4dichlorobenzene, methoxychlor, pentachlorophenol, DDT, and toxaphene. This preliminary assessment showed that Yam and Bambara nut consumed in Wukari contained certain level of organochlorine pesticide residues which may be detrimental to human health in the nearest future.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
