饮用水环境正受到城市、工农、矿业活动等多种来源污染物威胁,环境污染将导致饮用水中蓄积各种有毒有害物质。据报道,全世界饮用水中已发现756种有机物,其中致癌物20种、可疑致癌物23种、促癌物18种和致突变物56种[1]。我国生活饮用水来源主要是地下水与河流,但已有97%的地下水受到不同程度的污染,其中40%地下水的污染仍在不断加剧[2]。尽管饮用水消毒技术已经普遍应用,但在饮用水中仍发现氯化消毒副产物达300余
Drinking water environment is being threatened by many sources of pollutants such as cities, workers and peasants, and mining activities. Environmental pollution will cause various toxic and harmful substances to accumulate in drinking water. According to reports, 756 kinds of organic substances have been found in drinking water throughout the world, including 20 carcinogens, 23 suspected carcinogens, 18 carcinogens and 56 mutants [1]. The sources of drinking water in our country are mainly groundwater and rivers. However, 97% of the groundwater is polluted to varying degrees and 40% of the groundwater is still being polluted [2]. Although drinking water disinfection technology has been widely used, but still found in drinking water chlorination by-products of more than 300
