“…Water pollutants mainly through drinking water and skin contact into the human body, damage to human organs, threatening human health ( Xia et al, 2021 ). As non-carcinogenic pollutants, NO 3 – and F – are often used to assess non-carcinogenic health risks in river waters.…”

To explore the influence of different types of anthropogenic activity on the rivers, we investigate the major ion composition, sources and risk assessment of the karst stream (Youyu stream and Jinzhong stream), which are heavily influenced by mining activities and urban sewage, respectively. The chemical compositions of the Youyu stream water, which is heavily influenced by mining activities, are dominated by Ca2+ and SO42–. However, the chemical compositions of the Jinzhong stream water, which is heavily influenced by urban sewage, are dominated by Ca2+ and HCO3–. The Ca2+, Mg2+ and HCO3– in Jinzhong stream are mainly derived from rock weathering, while the Youyu stream is affected by acid mine drainage, and sulfuric acid is involved in the weathering process. Ion sources analysis indicates that the Na+, K+, NO3–, and Cl– in the Jinzhong stream mainly derive from urban sewage discharge; but NO3– and Cl– of the Youyu stream mainly derive from agricultural activities, and Na+, K+ are mainly from natural sources. The element ratios analysis indicates the ratio of SO42–/Mg2+ in Youyu stream (4.61) polluted by coal mine is much higher than that in Jinzhong stream (1.29), and the ratio of (Na++K++Cl–)/Mg2+ in Jinzhong stream (1.81) polluted by urban sewage is higher than Youyu stream (0.64). Moreover, the ratios of NO3−/Na+, NO3−/K+, and NO3−/Cl− in the agriculturally polluted Youyu stream were higher than those in the Jinzhong stream. We can identify the impact of human activities on streams by ion ratios (SO42–/Mg2+, (Na++K++Cl–)/Mg2+, NO3−/Na+, NO3−/K+, and NO3−/Cl−). The health risk assessment shows the HQT and HQN for children and adults are higher in Jinzhong stream than in Youyu stream and the total HQ value (HQT) of children was higher than one at J1 in the Jinzhong stream, which shows that children in Jinzhong stream basin are threatened by non-carcinogenic pollutants. Each HQ value of F− and NO3− for children was higher than 0.1 in the tributaries into Aha Lake, indicating that the children may also be potentially endangered.

“…An analysis that is a quantitative technique for assessing chemicals that are hazardous to the well-being of humans is the method of health risk assessment. Human health is at risk, and organs are harmed when water pollution comes into touch with the body, particularly via the skin and drinking water [8]. However, compared to the dermal route, ingestion was found to be a more severe mode of exposure [9] [10].…”

This research examines the condition of the water characteristics of the Pusur River to provide data regarding water quality status and risks to human health. In determining the water quality use the NSF-WQI, or National Sanitation Foundation-Water Quality Index based on the main water quality parameters, including temperature, fecal coliform, turbidity, pH, DO, COD, and nitrate. The WQI at the Sudimoro Village location is 37.50, Cokro is 43.54, Wangen is 39.51, Delanggu is 35.45, Juwiring is 38.05, and Taji Village is 34.92. From these six locations, the WQI values are all included in the bad criteria (scores of 26-50). The low WQI values at the six locations were influenced by the low values of the DO, nitrate, temperature, and fecal coliform sub-indices. This low value is related to anthropogenic activities in the region. Furthermore, the data were subjected to applications of the Chronic Daily Index (CDI) Hazard Quotient (HQ), and Hazard Index (HI) to reveal possible non-carcinogenic health risks from nitrate and cadmium contaminants. The hazard quotient through exposure to ingestion from each sampling point includes low risk, namely the value range of 0.1 < HI < 1 for adults and children. Water from rivers must be adequately treated before being used for domestic purposes.

“…Therefore, Taghvaee et al proposed a source-specific risk assessment method based on source analysis and risk assessment methods to carry out this work 17 . In recent years, source-specific risk assessment methods have attracted increasing attention, and have been widely applied in the analysis of various pollutants in air particulate matter 18 , heavy metals in road dust 16 , potential toxic elements in agricultural soil 19 and pollutants in river sediments 20 . The key to source-specific risk assessment is the source apportionment of PTEs.…”

As rapidly developing area of intensive agriculture during the past half century, the oases in the source region of the Tarim River have encountered serious environmental challenges. Therefore, a comparative analysis of soil pollution characteristics and source-specific risks in different oases is an important measure to prevent and control soil pollution and provide guidance for extensive resource management in this area. In this study, the concentration of potential toxic elements (PTEs) was analyzed by collecting soil samples from the four oases in the source region of the Tarim River. The cumulative frequency curve method, pollution index method, positive matrix factorization (PMF) model, geographical detector method and health risk assessment model were used to analyze the pollution status and source-specific risk of potential toxic elements in different oases. The results showed that Cd was the most prominent PTE in the oasis agricultural soil in the source region of the Tarim River. Especially in Hotan Oasis, where 81.25% of the soil samples were moderately contaminated and 18.75% were highly contaminated with Cd. The PTEs in the Hotan Oasis corresponded to a moderate level of risk to the ecological environment, and the noncarcinogenic risk of soil PTEs in the four oases to local children exceeded the threshold (TH > 1), while the carcinogenic risk to local residents was acceptable (1E−06 < TCR < 1E−04). The research results suggested that the Hotan Oasis should be the key area for soil pollution control in the source region of the Tarim River, and agricultural activities and natural sources, industrial sources, and atmospheric dust fall are the priority sources that should be controlled in the Aksu Oasis, Kashgar Oasis and Yarkant River Oasis, respectively. The results of this study provide important decision-making support for the protection and management of regional agricultural soil and the environment.
