“…In this study, the highest concentration of Pb was observed in mango (0.576 mg kg −1 ), which exceeded the FAO/WHO stipulated safe limits of 0.3 mgkg −1 ( Table 2 and Figure 2 ) [ 20 ]. The findings of this study were greater than those of other similar studies conducted in Uganda (0.32 mgkg −1 ) [ 26 ] and Addis Ababa (0.25 mgkg −1 ) [ 27 ], but less than those of studies conducted in Libya (1.824 mgkg −1 ) [ 28 ]. This is because the overuse of fertilizers in soils may increase the quantity of Pb in the soil [ 12 , 20 ].…”

“…The highest and lowest concentrations of Cr were found in bananas (0.773) and mango (0.728), respectively. The concentration of Cr in all fruit samples was below the FAO/WHO safe limit of 2.3 mgkg −1 [ 20 ], but higher than the findings of other similar studies conducted in Uganda (0.4 mgkg −1 ) [ 26 ]. This result revealed that all the studied fruits have a safe level of Cr, which may not pose health risks to consumers.…”

Background. Excess accumulation of potentially toxic elements in frequently consumed fruits is a serious threat to human health. The aim of this study was to determine the levels of cadmium (Cd), chromium (Cr), copper (Cu), and lead (Pb) and to estimate the noncarcinogenic and carcinogenic health risks associated with their daily intake in commonly consumed fruits in Bahir Dar town, northwest Ethiopia. Methods. Three types of fruits (mango, banana, and orange) were collected using a simple random sampling method from open markets in Bahir Dar town. Wet digestion was used, and the concentration of potentially toxic elements was analyzed in the edible portion of the fruits. The average daily intake (ADI), hazard quotient (HQ), hazard index (HI), and target cancer risk (TCR) were estimated to assess the human health risks posed by the intake of those potentially toxic elements from the consumption of the studied fruits. Results. The concentrations of Cr and Cu were lower than the maximum limit of normal values in mango, banana, and orange. However, the Pb and Cd concentrations (mg kg-1) in mango were 0.576 and 1.771, respectively, which exceeded the FAO/WHO recommended permissible limits of 0.3 mg kg-1 and 0.2 mg kg-1, respectively. The ADI of potentially toxic elements was found to be lower than the maximum permitted tolerable daily intake in the studied fruits, and the HI values (mgday-1 kg-1) of all studied potentially toxic elements were lower than one in banana and orange, except mango (3.69). The TCR values for Pb, Cd, and Cr in banana and orange were 7.16×10−4 and 7.15×10−4, respectively, which exceeded the recommended threshold risk limit (>1×10−4), but in mango (1.71×10−3), the level was above the moderate risk limit (>1×10−3). However, the TCR value in all the studied fruits was above the recommended safe limit (ILCR<1×10−6) set by the United States Environmental Protection Agency (US-EPA). Conclusion. The study revealed that the consumption of mango fruit in the studied areas may pose noncarcinogenic and carcinogenic adverse health effects.
