HEALTH RISKS ASSESSMENT OF HEAVY METALS (AL, CD, CR, CU, FE, NI, PB) LINKED TO THE CONSUMPTION OF USED FISH FRYING OILS USED BY GARBA TRADERS : CASE OF THE CITY OF DALOA

Palm oil remains the most used oil in Ivory Coast. However, its constant reuse, even used, by garba traders could present a health risk to the consumers. The objective of this study is to assess the carcinogenic and non-carcinogenic risks linked to metals, for consumers of garba in the city of Daloa. The methodology consisted of taking 15 samples of used oils in the city of Daloa between May and July 2024 in order to determine their heavy metal contents (Al, Cd, Cr, Cu, Fe, Ni, Pb) by Atomic Adsorption Spectroscopy (AAS). The results of the contents obtained were lower than the threshold values set by CODINORM, FAO and WHO for refined oils. The Hazard Index (HI) and Incremental Lifetime Cancer Risk (ILCR) values were all less than 1 and 10-6 respectively, indicating no significant risks to consumers. So, the used fish frying oils used by garba traders in Daloa are of satisfactory quality and they do not pose any significant risks to consumers.
