Heavy metals are released into the water system through various natural processes and anthropogenic activities, thus indirectly or directly endangering human health. The distribution, source, water quality and health risk assessment of dissolved heavy metals (V, Mn, Fe, Co, Ni, Zn, As, Mo, Sb) in major rivers in Wuhan were analyzed by correlation analysis (CA), principal component analysis (PCA), heavy metal pollution index (HPI), hazard index (HI) and carcinogenic risk (CR). The results showed that the spatial variability of heavy metal contents was pronounced. PCA and CA results indicated that natural sources controlled Mn, Fe, Co, Ni and Mo, and industrial emissions were the dominant factor for V, Zn and Sb, while As was mainly from the mixed input of urban and agricultural activities. According to the heavy metal pollution index (HPI, ranging from 23.74 to 184.0) analysis, it should be noted that As and Sb contribute most of the HPI values. The health risk assessment using HI and CR showed that V and Sb might have a potential non-carcinogenic risk and As might have a potential carcinogenic risk to adults and children in the study area (CR value exceeded target risk 10−4). At the same time, it was worth noting that As might have a potential non-carcinogenic risk for children around QLR (HI value exceeded the threshold value 1). The secular variation of As and Sb should be monitor in high-risk areas. The results of this study can provide important data for improving water resources management efficiency and heavy metal pollution prevention in Wuhan.

<p>Soils of urbanized and mining areas succeeded the main geochemical features of parent materials, as well as accumulate potentially toxic elements (PTE) from different anthropogenic sources. The latter resulted in the change of soil chemical composition and high level of PTE which may have negative reflection on people’s health. In this study 207 soil samples were collected from the entire territory of the city of Alaverdi hosting Alaverdi copper smelter. After the determination of Fe, Ba, Mn, Co, V, Pb, Zn, Cu, Cr, As and Mo concentrations by XRF the established data set was subjected for the PTE induced health risk assessment. In this study two commonly used health risk assessment approaches - Summary pollution index (Zc) [1]–[3] and Hazard Index (HI, US EPA) [4] were used to assess human health risk posed by the content of studied PTE in soil of Alaverdi city. The result showed that the detected concentrations are mainly the result of superposition of PTE contents introduced into the environment from natural mineralization processes and Alaverdi copper smelter related activities. The health risk assessment showed that the Zc values belonging to the extremely hazardous level has point-like shape and are surrounded by the hazardous and moderately hazardous levels, respectively. Summary pollution index showed that approximately 53 % of the city territory including the residential part is under the risk suggesting the increase in the overall incidence of diseases among frequently ill individuals, functional disorders of the vascular system and children with chronic diseases [1]. The US EPA method were in line with the results of the Zc and indicated that the observed contents of elements are posing non-carcinogenic risk to adult mainly near the copper smelter. In the case of children single-element non-carcinogenic risk values greater than 1 were detected for As, Fe, Co, Cu, Mn, Pb and Mo in 122, 95, 86, 10, 10, 9 and 6 samples out of 207 soil samples and the mean HQ values decrease in the following order: As(2.41)>Fe(1.14)>Co(1.09)> Mn(0.61)>Pb(0.41)>Cu(0.32)>V(0.19)>Mo(0.11)>Cr(0.05)>Ba(0.03)>Zn(0.02). The multi-elemental non-carcinogenic risk observed in the entire territory of the city indicating an adverse health effect to children. The results of this study suggesting the need of immediate risk reduction measures with special attention to arsenic.</p><p><strong>References:</strong></p><p>[1]         E. K. Burenkov and E. P.

Abstract We investigated the cadmium content in soils and rice in Cha Hayang, Wuchang, Fangzheng, Xiangshui, and Jiansanjiang areas of Heilongjiang Province, and characterized the effect of rice intake on human health. The samples were analyzed by ICP-MS, and the cadmium transfer in soil-rice system was modeled by the Nemero comprehensive pollution index method. The health risk assessment model was used to study the status of cadmium pollution in rice and its health risk assessment for adults and children. The results showed that the average contents of cadmium in rice were 0.003 (Cha Hayang), 0.016 (Wuchang), 0.006 (Fangzheng), 0.006 (Xiangshui), and 0.005 (Jiansanjiang) mg kg-1. The prediction model developed in this study, including the total heavy metals and pH value of the soil, effectively described the transfer of cadmium in the soil-rice system of Wuchang, Chahayang and Xiangshui paddy fields (with R2 between 0.256 and 0.468). The pollution index of the study area was less than 1. The comprehensive pollution index was 0.037<1, sugesting no pollution, and the comprehensive pollution index was between 0.059 and 0.158. The health risk index of carcinogenic heavy metal cadmium to adults and children in Cyang and JianSanjiang areas was lower than that recommended by USEPA (1 × 10-4), suggesting no risk of cancer. However, the mean values in Wuchang, Fang Zheng and Xiangshui were higher than the maximum acceptable risk recommended by USEPA, suggesting a risk of cancer.
