Abstract Health risk assessment of heavy metals is crucial before large scale applications of municipal solid waste (MSW) as organic fertilizer. This study aimed to estimate Pb, Cd and Cr accumulation and health risk in faba bean (Vicia faba L.) grow on soils amended with MSW compost, biochar and co-composted biochars (5%, 15% and 25% w/w). The heavy metal concentrations were measured by flame atomic absorption spectroscopy. Bioaccumulation Factor (BAF), Estimated Daily Intake (EDI), Hazard Quotient (HQ) and Hazard Index (HI) were calculated. Results showed that Pb, Cd and Cr concentrations in the amended soils and faba bean grain were lower than WHO permissible levels. The EDIs of Pb, Cd and Cr in grains for all amendments were much lower than the reference doses established by USEPA and FAO/WHO. HQs and HIs of heavy metals were < 1 for all amendments indicating that consumption of faba bean grow on MSW compost, khat biochar and co-composted biochar collected from Jimma city was safe related to human health risks. Low accumulation of heavy metals in faba bean indicating that the low fraction of e-waste in the MSW. Since faba bean grain is not accumulator, it’s potential of heavy metals excluder needs further explorations.

This research focused on the contents of the five most bio-toxic heavy metals, As, Cd, Hg, Cr, and Pb of 26 municipal solid waste (MSW) samples from the Eastern Guangdong Area. To investigate the apportion of the heavy metal source, Pearson correlation and principal component analysis (PCA) were introduced as major approaches. The health risks posed to MSW workers exposed to heavy metals in MSW were assessed using a Monte Carlo simulation combined with the US Environmental Protection Agency Health Risk Assessment Model. The As, Cd, Hg, Cr, and Pb contents of the east Guangdong MSW were (0.76 ± 0.75), (2.14 ± 4.44), (0.11 ± 0.14), (55.42 ± 31.88), and (30.67 ± 20.58) mg/kg, respectively. Hg, Cr, and Pb were potentially derived from glass, textile, food waste, and white plastic, while As and Cd were mainly derived from soil and food waste in the MSW. The non-carcinogenic risks of heavy metal in MSW exposure to MSW workers could be ignored. However, the heavy metals in MSW might pose carcinogenic risks, with the probabilities for male and female workers being 35% and 45%, respectively. The non-carcinogenic and carcinogenic risk indices were slightly higher for female workers under the same exposure situations.

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
