Abstract

Aims: The aim of this study was to assess the level of organochlorine pesticide (OCPs) residues in some selected kolanuts in Côte d’Ivoire.

Study Design: Kolanuts samples were collected from farmers, collectors and urban stores in 3 regions, in particular western, southwestern and eastern of Côte d’Ivoire.

Place and Duration of Study: Health Department of Hydrology Health and Toxicology, Training and Research Unit of Pharmaceutical and Biological Sciences, Abidjan, Côte d’Ivoire, running 2017-2018.

Methodology: A total of 225 samples were analyzed using a gas chromatograph equipped with an electron capture detector.

Results: Data showed that all 17 pesticides analyzed were detected in kolanuts samples. Statistical analysis indicated no significant difference in OCPs sub-group used by farmers and traders in all producing region. The mean levels of HCHs, DDTs and cyclodienes were ranged from 0.07± 0.01– 0.91± 0.05 mg/kg, 0.15±0.01 – 0.61±0.12 mg/kg and 0.12±0.03 - 0.84±0.46 mg/kg, respectively. Otherwise, farmer’s levels of OCPs were lower than those detected in kolanuts from collectors and urban stores samples. Thus, compared to the MRL set by the World Health Organization/Food and Agricultural Organization, the farmer’s samples are lower than limits fixed, unlike the contents registered with collectors and urban stores.

Conclusion: There is the need to keep monitoring ecotoxicological chemical substances in kolanuts produced in Côte d’Ivoire and take steps that ensure health safety of end users. Care should be taken since residues could pose chronic health risk for adults and children.

Keywords:
