Contamination of the environment with toxic metals can bring about possible pollution of cassava. Eating food crops contaminated with toxic metals is the main food chain pathway for human exposure. Some trace metals like Manganese, Copper, Zinc, Nickel, Lead, Selenium, Strontium, Niobium, Vanadium, and Iron in soil and their accumulation in cassava tubers collected from farms around abandoned mining sites at Ishiagu in Ebonyi State, Nigeria were analyzed with X-ray fluorescence spectrometer to evaluate the potential health risk to the dweller adults and children. Results show that there is an extensive build-up of toxic metals in farmland soils around the abandoned mining sites at Ishiagu, Ebonyi State. Levels of toxic metals in cassava grown in Farms around the mines were substantially higher (P < 0.05) than in cassava tubers grown in the reference soil, and exceeded the permissible limits set by the World Health Organization. In addition, this investigation reveals that both adults and children consuming cassavas grown in the area ingest appreciable quantities of the metals studied. The health risk indicator quantities of greater than 1 signal a strong presence of health risks connected with the eating of contaminated cassava.

The water range from Pb (1.439 – 1.715), Cu (0.234 – 0.377), Cd (0.838 – 1.346), Zn (0.448 – 1.110), Cr (0.144 – 0.794), Mn (0.777 – 2.011) and As (0.584 – 1.341) mg/L. The range in soil was Pb (67.5 – 120), Cu (8.51 – 32.5), Cd (0.21 – 1.72), Zn (70.8 – 85.6), Cr (15.8 – 29.5), Mn (14.6 – 19.1) and As (52.0 – 198) mg/kg and in the vegetables in the range of Pb (0.177 – 0.545), Cu (0.073 – 0.748), Cd (0.005 – 0.019), Zn (0.264 – 0.915), Cr (0.089 – 0.158), Mn (0.162 – 0.253) and As (0.032 – 0.245) mg/kg. The study shows that the transfer coefficient of the heavy metals to vegetable was less than one (< 1). The estimated daily intake (DIM) of heavy metals from vegetables irrigated with tin mine pond water were in the order: Cd > Zn > Mn > Cr > Cu > Pb > As. The health risk index (HRI) of all the studied heavy metals indicated that all vegetables were safe with no risk to human health except for Cd. health risk assessment of heavy metals in consumption of vegetables irrigated with tin mine pond water in Jos - South, Plateau State

In view of ensuring healthy agricultural foods for human consumption, this study assessed the human health risk implicated in selected heavy metals in some commonly consumed vegetables, tubers, nuts and fruits grown around the quarry sites at Ishiagu, Ebonyi State, Nigeria. Samples from agriculture area of Umudike, Abia State, Nigeria, constituted the control. The concentration of Mn, Zn, Fe, Cu, Cd, and Pb, were determined using atomic absorption spectrometry. The potential non-carcinogenic health risk for consumers which included Estimated Daily Intake (EDI) and Target Hazard Quotients (THQ) for Pb, Fe, Mn, Zn, Cd and Cu while carcinogenic health risk using Cancer Slope Factors (CSF) was established for Cd and Pb. Relative abundance of heavy metals across the locations and all samples was in the order Fe > Mn > Zn > Pb > Cu > Cd. There was statistical significant effect of quarrying activities on the concentration of the heavy metals (Fe, Mn, Zn, Pb, Cu, Cd) at p < 0.05 level. Based on the observed bioconcentration factors, cassava showed more hyperaccumulation potential compared to other samples. Pumpkin and bitter leaf also could be used in remediation owing to their high bioaccumulation index for Pb and Zn. THQ obtained for Mn and Pb were >1 indicating that the residents at the quarry site may be exposed to potential non-carcinogenic health risk due to Mn and Pb intoxication. With respect to US EPA prescriptions, average carcinogenic risk values obtained for Pb and Cd in this study indicated a lifetime (70 years) probability of contracting cancer suggesting that they be placed for further consideration as chemicals of concern with respect to the assessed locals.Keywords: health risk assessment, bioconcentration factors, daily intake of heavy metals, target hazard quotient, carcinogenic risk, heavy metal.
