Evaluation of Carcinogenic and Non-Carcinogenic Health Risk of Heavy Metal Exposures from Some Local Fruits in Katsina State, North West Nigeria

This work was carried out to evaluate the heavy metals (Cr, Cd, Fe, Ni, Mn, Pb and Zn) pollution load health risks population of some local fruit samples in Katsina state Nigeria. Results from this study have shown that except for mean concentration (1.152-1.623) Cd (0.053-0.092), (mg/kg) range values Fe (1.728-1.954), Mn (0.321-0.502) Zn (0.263-0.967 ppm) were generally below maximum allowable these metals. The risk level Target Hazard Quotient 1(< 1) recorded all evaluated population, indicating a no non-carcinogenic adverse effect on population. Incremental Lifetime Cancer Risk metal at threshold limit (>10−4) sampled fruits adults, while adults children within moderate (>10−3). cumulative cancer (∑ILCR) studied (>10−3) above (>10−2) children. results suggested intake State is public concern as it may lead an increase cases.
