Investigation of Drinking Water Quality and Population Health Risk Assessment in a Poor Rural Area
Work(2021)
Abstract
BACKGROUND: The quality and safety of drinking water directly affect the health of the local population. However, due to the limited conditions in poor rural areas, the safety of drinking water is more prominent. OBJECTIVE: It aimed to ensure the safety of drinking water quality and population health in poor rural areas. METHODS: A rural poor area was taken as an example, the drinking water plants were monitored during wet season and dry season, respectively, and the water quality indicators of rural drinking water in the city in 2019 were detected and analyzed. Finally, based on the non-carcinogenic risk and carcinogenic risk evaluation model proposed, the health risk assessment of chemical pollutants in drinking water was carried out. RESULTS: In 2019, the qualified rate of drinking water in rural areas of the city was generally low. The average annual carcinogenic risk of drinking water in poor rural areas of the city was 1.57×10–6 (a–1), and the average annual non-carcinogenic risk was 5.38×10–9 (a–1). CONCLUSION: The health risk assessment model proposed can well evaluate the health risks of drinking water. The research provides a scientific basis for the risk management of drinking water of relevant departments.
