Abstract:
Objective:To learn about the progress of prevention and control of drinking-water-borne endemic arsenic poisoning in Henan Province, and provide scientific basis for achieving the goal of eliminating high arsenic hazards as scheduled.Methods:From July to August 2019, in accordance with the requirements of the National Monitoring Program for Drinking-water-borne Endemic Arsenic Poisoning, a general survey was carried out in 26 high-arsenic villages in 6 counties of Henan Province to investigate the water improvement situation and the operation of water improvement projects, and the arsenic content in drinking water of households was measured, meanwhile, the arsenic poisoning status of permanent residents in high-arsenic villages was investigated.Results:All 26 villages with high arsenic content in the province had undergone water improvement, with a water improvement rate of 100.00%. A total of 18 water improvement projects were investigated in 26 high-arsenic villages, all of which were operating normally. Twenty-six water samples were collected, and the arsenic content in the household water was < 0.01 mg/L, which met the sanitary standards for drinking water. No patient of endemic arsenic poisoning was found during the survey.Conclusion:In Henan Province, the drinking-water-borne endemic arsenic poisoning has been effectively controlled, and the prevention and control achievements should continue to be consolidated in the future.
