Abstract
This study evaluated carcinogenic and non-carcinogenic effects of metals in commonly consumed protein food samples collected from three states in Southwestern Nigeria. One hundred and fifty food samples (crayfish, fish, meat and cowskin) were collected and analyzed for Cd, Cu, Cr and Pb using the standard method. Data were evaluated for descriptive and inferential statistics using SPSS for Windows (22.0). The health risk assessments of metals (Cd, Cu, Cr, Pb) were calculated for non-cancer indices (hazard quotient, HQ and hazard index, HI) and cancer risk (CR). Results for Cd varied from 0.85â±â0.11âmg kgâ1in raw fish to 1.20â±â0.39âmg kgâ1in crayfish; Cr from 2.18â±â0.53âmg kgâ1in smoked fish to 2.71â±â0.32âmg kgâ1in crayfish, while Pb ranged from 1.40â±â0.20âmg kgâ1in smoked meat to 2.34â±â0.62âmg kgâ1in cowskin. Cu showed higher significant (pâ<â0.05) concentration in crayfish (19.92â±â1.03âmg kgâ1) than other protein foodstuffs. The health risk data revealed the average HI values of metals (in raw meat, smoked fish, cowskin and crayfish) greater than 1.0 indicating non-carcinogenic adverse health effects. The data on carcinogenic effects revealed CR values greater than the permissible limit of 1.0âÃâ10-4 for Cd and Cr indicating cancer risk on consumption of food samples.
