摘要

Fruits and vegetables contaminated with heavy metals can pose health risks to humans. Noncar cino genic and carcinogenic risks of some metals (Cu, Cd, Cr, Pb, and Ni) in carrots cultivated in Wudil, Kano, Nigeria was investigated by calculating the chronic daily intake (CDI), target hazard quotient (THQ), hazard index (HI), and carcinogenic risk (CR) of the metals. The mean concentrations of the metals were in the following decreasing order: Cu>Cr>Ni>Pb>Cd. The levels of all the metals were below themaximum tolerable limit set by FAO/WHO. The THQ for the heavy metals were all less than one (THQ Pb>Cu>Cd>Ni. Cr was the major contributor to the total non-carcinogenic risk and accounted for 57.61% of the total risk, while Pb, Cu, Cd, andNi contributed 15.64%, 12.76%, 7.41%, and 6.58% respectively. The CR were all below the upper limit of 1 x 10~(-4), suggesting that lifetime exposure to these metals through the consumption of carrots did not pose a cancer risk to the population. The levels of the investigated metals in carrots in the area did not pose any risk to the consumers. However, there is a need to monitor the metals on regular basis to ensure the safety of the consumers.
