Polycyclic aromatic hydrocarbons (PAHs) are pervasive environmental pollutants of high toxicity. Due to their lipophilic characteristics, they tend to accumulate in the food chain. Human exposure to PAHs seems inevitable and the main route of exposure is food. The presence of PAHs in kolanut could cause serious health problem for consumers and slow down the export to new markets, which would constitute a significant shortfall for all actors in the kola sector.This study aimed to detrmined the Polycyclic Aromatic Hydrocarbons (PAHs) levels in kolanuts and estimate the exposure risks of nuts consumption by Ivorian population. Samples were collected from farmers, rural collectors, urban stores in districts (Mountains, Comoe, Lagoons, Down-Sassandra) and big storage centers of Anyama and Bouake cities. Concentrations of 9 PAHs (B[a]P, B[b]F, B[a]A, CHR, FLA, B[k]F, D[ah]A, B[ghi]P and IcdP) were measured using an Adept brand High Performance Liquid Chromatograph (HPLC) equipped with an ultraviolet (UV) / visible CE 4200 (CECIL) detector. Data showed the average concentration of PAHs in kolanuts at 1.22 ± 0.86 µg/kg. The PAHs concentrations expressed in BaP equivalent (BaPeq) ranging from 0.0009 ± 0.0003 µg/kg-BaPeq to 0.88 ± 0.24 µg/kg-BaPeq for B[ghi] P and D[ah]A. Based on the concentrations and the daily consumption of kolanuts estimated at 0.6 g/person in Côte d'Ivoire, the intakes values estimated of PAHs vary from 6.10-5 µg-BaPeq /day to 6.48.10-4 µg-BaPeq/day with an average of 3.06.10-4 ± 6.6.10-5 µg-BaPeq/day. The exposure daily doses (EDD) are all lower than the toxicity reference values (5 ng-BaPeq/kg BW/d). Thus, the occurrence of a toxic effect from PAHs after kolanuts consumption is very unlikely since the hazard quotient (HQ) are all less than 1. The risk of developing cancer is less than one case per 1,000,000 people.

Aims: The current study targets the achievement of a reliable process for the determination of PAH contents in kola nuts for better appreciation of the risks incurred from the consumption of such food products. Study Design: Kolanuts collected from two big storage centers were analyzed after the validation of the proposed analytical method. Place and Duration of Study: Central Laboratory for Food Hygiene and Agro-Industry, LANADA in Abidjan, Côte d’Ivoire, running 2018. Methodology: Two references were used for the validation of the analytical method, namely the French standard NF V 03-110 and the ISO directive ISO/DIS/15753 applicable in Liquid Chromatography. The PAH contents of some samples collected from different stores were then determined. Results: From the data, a significant regression chart was recorded for the PAH detection graphs. All the analysis exhibited good linearity with significant correlation coefficients (R²˃ 0.99). The relative standard deviations of the repeatability and reproducibility assays are below 3%, whereas standard additions of PAH are fully recovered, with percentages close to 100%. Conclusion: Using this analytical method, kola nuts contamination by PAH have been determined with satisfactory.This analytical method could help in ensuring effective sanitary control at different critical points of kola nut distribution channel for promoting a good management of the toxicity concerns in such products.
