Standard Value

In the present study, concentrations of heavy metals (Cu, Zn, Pb, Cd) in soil and wheat grains of the agricultural areas around Baiyin, a non-ferrous metals mining and smelting base, were detected. Meanwhile, the potential health risk of the heavy metals to adult males, adult females and children was estimated using non-carcinogenic health risk assessment model: Hazard Quotient (HQ) and Hazard Index (HI). The results showed that only the level of Cd in all soil samples exceeded the permissible limit of the environmental quality standard for soil, and its average level surpassed the standard value by 4 times. In wheat grains, the levels of Pb and Cd were 50 times and 8 times of the limited values of hygienic standard for grain respectively, while Cu and Zn concentrations did not surpass the standard value. The potential health risk due to single heavy metal for all the three investigated populations followed the sequence of HQPb＞HQCd＞HQCu＞HQZn＞1 (assumed the local inhabitants wholly food on wheats), suggesting that each of the four heavy metals were making negative effect on population health, of which the situation of Pb and Cd should be paid more attention due to their significant adverse effect. The total potential health risk due to the four heavy metals followed the sequence of HIchildren＞HImales＞HIfemales＞1 (assumed that the health risk due to the four heavy metals is additive), suggesting that the heavy metals were producing adverse effect on population health, and were especially hazardous for children. According to the research results, the government is suggested to strictly control the quality of irrigation water and remove the heavy metals from agricultural soil in order to ensure the safety of foodcrop production and local inhabitants.

Exposure Pathway

Using the case of Ulaanbaatar, Erdenet, and Darkhan cities from Mongolia, the study aimed to assess the contamination level and health risk assessment of heavy metals (As, Cr, Pb, Ni, and Zn) in urban soil. A total of 78 samples was collected from a variety of functional areas. The geoaccumulation index (Igeo) and integrated pollution index (IPI) were used in pollution assessment, while the health risk was scored using a hazard quotient (HQ) and health index (HI) for non-carcinogenic heavy metals, as well as a lifetime average daily dose (LADD) for carcinogenic heavy metals. The results show that the concentration of heavy metals in the soil samples taken from Darkhan city, which presented “uncontaminated” values in terms of Igeo for all metals, was relatively lower than other cities within the contamination assessment. Furthermore, the Igeo value signified “uncontimated to heavily contaminated” soil in the Ulaanbaatar and Erdenet cities. Typically, as for the IPI that observed similar trends with Igeo, the mean IPI values in Ulaanbaatar, Erdenet, and Darkhan were 1.33 (moderate level of pollution), 1.83 (moderate level of pollution), and 0.94 (low level of pollution), respectively. In terms of the assessment of potential health risk, there was a particular or different level of ingestion, dermal contact, and inhalation exposure pathway for human health. Among these three different pathways, the ingestion was estimated by the main contributor for health risk. Each value of HQ and HI indicated that soil heavy metals of studied cities were at a safe level (<1) or had the absence of a significant health risk there. In addition, the potential health risk for children was greater than for adults, where heavy metal values of HI for children had a high value compared to adults. We estimated carcinogenic risks through the inhalation exposure, and as a result, there were no significant risks for human health in the studied cities from three elements (As, Cr, and Ni).
