“…Average Ni concentrations ranged from 0.17 mg/kg FW up to 0.94 mg/kg FW, with maximum levels being detected in root vegetables from the M area and fruits from the R area. Concentrations close to this range (0.07–2.16 mg/kg FW) have also been found in common vegetables and fruits collected from Bangladesh [ 12 ], Armenia [ 16 , 19 ], Kosovo [ 56 ], Turkey [ 58 ], Brazil [ 59 ] and Ethiopia [ 60 ]. Related to Pb, the measured values in analyzed vegetables and fruits varied between 0.08 mg/kg FW and 2.45 mg/kg FW, with the maximum values being above MAL (0.5 mg/kg FW) in most fruits and vegetables sampled from the R area.…”

In this study, we conducted a noncarcinogenic risk assessment of consuming vegetables and fruits grown in two old mining areas from the Banat area of Southern Carpathians (Romania), Moldova Veche (M) and Rusca Montana (R) and in a nonpolluted reference area located near the village of Borlova (Ref). Concentrations of Fe, Mn, Zn, Cu, Ni, Cd and Pb in soils and commonly eaten vegetables and fruits were measured and used for calculating the weighted estimated daily intake of metals (WEDIM), the target hazard quotients (THQ) and the total target hazard quotients (TTHQ) for normal daily consumption in adults. Levels of certain metals in soils and plants from the R area (Pb) and the M area (Cu) were higher than those measured in the Ref area—and often exceeded normal or even alert-threshold levels. TTHQs for the R area (1.60; 6.03) and the M area (1.11; 2.54) were above one for leafy vegetables and root vegetables, respectively, suggesting a major risk of adverse health effects for diets, including these vegetal foodstuffs. Moreover, THQ and TTHQ indicated a higher population health risk for the R area than for the M area, with the Ref area being a safe zone.

“…Comparing the ADD with the acceptable daily intake (Table 8), it could be seen that ADDs were generally low and suggests that the daily doses of heavy metals from the soil are acceptable. In soil and vegetables from Mojo area, Ethiopia [48] and dumpsite soils in southeastern, Nigeria [46], low values for ADD were also obtained.…”

The purpose of this study was to determine and assess the health risks associated with heavy metal contamination for residents in the vicinity of floodbasin in Amakohia, Owerri. Overall, 20 composite samples were collected at two depths (5 and 10 cm) following a simple random sampling technique and analyzed for Pb, Cu, Fe, Mn, Zn and Cr using Perkin Elmer AAnalyst 400 AAS following validation. The mean concentration of metals were 15.

“…The average values of health risk of all studied HMs are described in Table 8. The health risks of As, Cd, Cr, Ni and Pb were all below the maximum acceptable level (1 × 10 -6 ), therefore, there is no health risk (38,39).…”

Background: Heavy metals (HMs) contamination from industrial wastewater is a major environmental problem that has been increasing in the past few years. The purpose of this study was to investigate the current status of HMs contamination in Bu-Ali industrial town, Hamedan, western Iran. Methods: The concentration of 9 serious HMs (arsenic, cadmium, chromium, copper, iron, lead, manganese, nickel, and zinc) in groundwater samples was studied during spring 2017. In order to evaluate water quality for aquaculture and drinking purposes, heavy metal evaluation index (HEI), heavy metal pollution index (HPI), and contamination (Cd) indicator were calculated. Health risk of HMs was also calculated to assess the risk of cancer. Results: The results showed that the mean concentration of the HMs according to the Cd index was as follows: Pb > Ni > Cr > Fe > Cd > As > Cu > Zn > Mn. The mean HEI and HPI values were 89.1 and 815.5, respectively. The results also showed that there was no relationship between the HMs concentration and cancer risk. Conclusion: The concentration of the studied HMs in most samples was higher than the permissible limit for drinking water. The HEI and HPI values in high-risk samples were higher than the permissible limit of drinking water, therefore, there is high risk and limitation for aquatic life, but there is no risk of cancer.
