【摘要】 本文以新疆古尔班通古特沙漠腹地的东道海子湖水为对象,研究东道海子湖水中苯系物的污染特征,并对湖水中苯系物的潜在生态危害进行分析评价。结果表明:东道海子湖水中苯系物的含量均满足我国水环境质量一级标准,苯的浓度仍然小于我国生活饮用水卫生标准中规定的0.01 mg/L,但经过健康风险评价,发现其仍会对人体产生一定的致癌风险。苯、甲苯、乙苯、邻二甲苯、间二甲苯、对二甲苯的非化学致癌物风险(HQ)值远低于1,表明各类苯系物均无非致癌物的化学风险。更多还原

【Abstract】 This paper studies the pollution characteristics benzene series in Dongdaohaizi Lake in the hinterland of the Gurbantunggut Desert in Xinjiang, and analyzes and evaluates the potential ecological hazards of benzene series in the lake water. The results show that the content of benzene series in the Dongdaohaizi Lake meets the Level I standard of water environment quality in China. The concentration of benzene is still less than 0.01 mg/L stipulated in the hygienic standard of drinking water in China. However, health risk assessment shows that they still have certain carcinogenic risks to humans. The non-chemical carcinogen risk(HQ) values of benzene, toluene, ethylbenzene, o-xylene, m-xylene and p-xylene are far lower than 1, indicating that none of benzene series has the chemical risks of non-carcinogens.更多还原
