To determine the spatiotemporal distributions and human health risks of fluoride and arsenic in the rivers of Kyrgyzstan as influenced by mining and other industries, 169 water samples were collected from the main rivers and tributaries of Kyrgyzstan from 2016 to 2018. Through the use of cold and hot spot analysis, multivariate statistical analysis and health risk assessment model, the results indicated that the fluorine and arsenic concentrations in river waters increased year by year from 2016 to 2018. In total, 2.38%, 3.26% and 10.64% of the analyzed samples exceeded the drinking water standard of a maximum permissible limit of 1 mg/L for fluoride, and 0%, 1.09% and 2.13% of the samples exceeded the limit of 10 µg/L for arsenic in 2016, 2017 and 2018, respectively. The gathering areas for high fluorine concentrations were mainly distributed in the Issyk-Kul Basin, Chu River Valley and Fergana Basin, and the gathering areas for high arsenic concentrations were mainly concentrated in the Chu River Valley and southern Fergana Basin. Although fluorine and arsenic were not found to exceed the limits simultaneously, the two pollutants accumulated high values in the southern Fergana Basin in 2018, which indicated the risk of joint poisoning. The distributions of high fluorine and arsenic were found to be determined by mining, industrial and agricultural activities, but not by natural sources. From 2016 to 2018, arsenic concentrations in the river water of Kyrgyzstan created a high risk of carcinogenesis by the ingestion intake exposure route, which resulted in the total risk of health hazards to children and adults caused by fluoride and arsenic to exceed the maximum acceptable ranges. Therefore, further monitoring and management are urgently needed.

To determine the spatiotemporal distributions of fluoride and arsenic in the rivers within the mining districts of Kyrgyzstan and health risks associated with the use of these rivers, a total of 169 water samples were collected from the main rivers and tributaries of Kyrgyzstan from 2016 to 2018. Through the cold and hot spot analysis, multivariate statistical analysis and health risk assessment model, the results indicated that the fluoride and arsenic concentrations in river waters increased year by year from 2016 to 2018. According to the World Health Organization (WHO) drinking water guidelines, 0%, 1.09% and 1.06% of the analyzed samples exceeded the limit for fluoride (1.5 mg/L), and 0%, 1.09% and 2.13% of the samples exceeded the limit for arsenic (10 µg/L) in 2016, 2017 and 2018, respectively. The gathering areas for high fluoride concentrations were mainly distributed in the Issyk-Kul Basin, Chu River Valley and Fergana Basin, while high arsenic concentrations were mainly observed in the Chu River Valley and southern Fergana Basin. Although fluoride and arsenic were not found to exceed the limits simultaneously, the two pollutants accumulated high values in the southern Fergana Basin in 2018, which indicated the risk of joint poisoning. From 2016 to 2018, arsenic concentrations in the river water of Kyrgyzstan created a high risk of carcinogenesis by the ingestion intake exposure route, which resulted in the total risk of health hazards to children and adults caused by fluoride and arsenic to exceed the maximum acceptable ranges. Therefore, the national environmental protection department in Kyrgyzstan should strengthen the dynamic monitoring of arsenic concentration in the rivers, and related scientific research institutions should conduct more in-depth research on the migration and transformation process of pollutants, the toxic mechanism, and even the substantive countermeasures in the future.

In high-fluorine geological background areas, the supergene geochemical process of fluorine has an impact on regional environmental health and safety, which has long been the focus of attention. However, in karst areas characterized by a high incidence of endemic fluorosis, the migration and transformation of fluorine in surface water have not received sufficient attention. This study investigated the joint influence of the weathering and erosion of carbonate rocks and coal-bearing strata on a typical small watershed. Accordingly, 239 samples representing 13 periods of hydrochemical samples were systematically collected to clarify the source, migration, and transformation characteristics of fluorine in surface water. The results revealed that the pH of the Huatan River was low in the rainy season and high in the dry season. The annual variation range of fluorine concentration was 0.11–0.40 mg/L. Although mining development produced acid mine drainage with high fluorine concentration, its impact at the watershed scale appeared to be limited. In terms of spatial scale, the concentration of fluorine in the Huatan River increased gradually from upstream to downstream. The dissolution of fluorite and other fluorine-bearing minerals had not reached the saturation state. The fluorine in the watershed primarily came from the dissolution of fluorine-bearing minerals, followed by the contribution of atmospheric precipitation. The release of fluorine adsorbed on the surface of clay minerals was not the main source of this element. The leaching of the watershed was shown to represent a critical transport process concerning fluorine in the Huatan River, and evaporation had a notable impact on the enrichment of fluorine in water.
