Health Risk Assessment of Main Pollutants in Sources of Drinking Water in Rongchang County
摘要
Abstract
Objective] To assess the health risk of main pollutants in sources of drinking water in Rongchang County.[Method] Water quali-ty and pollution sources of eight sources of drinking water in Rongchang County were monitored and investigated, and the main pollutants in water environment of each source of drinking water were evaluated preliminarily by using the health risk assessment model recommended by the US Environmental Protection Agency ( EPA) .[ Result] There were different levels of pollution from nitrogen, phosphorus and organic matter in the monitored reservoirs, and there was no heavy metal pollution.The highest individual risk of non-carcinogens was ammonia nitrogen, fol-lowed by mercury and cyanide, while the lowest was volatile phenol, but they were lower than the maximum acceptable risk level recommen-ded by ICRP in the dry and wet season.The individual risk of hexavalent chromium was higher than the maximum acceptable risk level recom-mended by ICRP in the dry and wet season, while the individual risk of arsenic was lower than the maximum acceptable risk level recommen-ded by ICRP in the dry and wet season.[ Conclusion] The damage of chemical carcinogens to human health is far more than that of non-car-cinogens, and hexavalent chromium is the main toxic pollutant to human health , so the management and control of hexavalent chromium is an effective measure to ensure the safety of water at sources of drinking water .关键词
