Abstract:
Objective:To learn about the operation of arsenic reduction and water improvement projects and the present situation of arsenic level in drinking water in drinking water type endemic arsenic poisoning areas in Jinzhong City, Shanxi Province.Methods:From May to August 2023, in accordance with the requirements of the "Investigation Plan for Arsenic Content in Drinking Water of Residents in Arsenic Exposed Areas of Shanxi Province", 29 high arsenic villages in the drinking water type endemic arsenic poisoning historical areas of Pingyao County, Jiexiu City and Qi County in Jinzhong City, Shanxi Province were selected as monitoring villages to investigate the operation of water improvement projects. The drinking water samples of village residents were collected and water arsenic level was measured by hydride atomic fluorescence spectrophotometry. At the same time, monitoring of the operation of water improvement projects and water arsenic level for residents within adjacent local areas were carried out in townships where 29 high arsenic villages located.Results:In 2023, a total of 29 high arsenic villages in 3 counties (cities) of Jinzhong City, Shanxi Province were monitored, all of which had undergone water improvement and all water improvement projects were operating normally. The range of water arsenic level was 0.000 - 0.047 mg/L, with 27 high arsenic villages had water arsenic level < 0.01 mg/L. A total of 81 natural villages within the adjacent local areas of high arsenic villages in Jinzhong City were monitored, all of which had undergone water improvement and the water improvement projects were operating normally. The range of water arsenic level was 0.000 - 0.043 mg/L, and there were 4, 7, and 2 natural villages in Pingyao County, Jiexiu City and Qi County with water arsenic level ranging from 0.01 to 0.05 mg/L.Conclusions:All high arsenic villages in Jinzhong City, Shanxi Province have completed water improvement, and the water improvement projects are operating normally. The water arsenic level in most high arsenic villages meets the national drinking water standard (< 0.01 mg/L).
