摘要
系统调研监测了南水北调山东受水区济南市内山区水库和引黄水库中污染物的激素水平,利用荧光素酶报告基因法（CALUX）深入分析了水中所含二恶英、雌激素、雄激素、肾上腺素等4类主要内分泌干扰物（EDCs）的综合激素效应。研究结果表明,所有水库水中雄激素、肾上腺素的综合激素效应均低于方法的检出限,二恶英和雌激素的激素效应检出含量分别为0.009-0.250ng 2,3,7,8-TCDD TEQ/L、0.040-0.250ngE2TEQ/L。山区水库水水质总体优于引黄水库水,全年秋、冬两季雌激素和二恶英含量高于春、夏两季。与其他国家相比,水库水二恶英含量较高,雌激素含量较低,雄激素和肾上腺素污染风险较小。常规水处理工艺对于雌激素的去除具有一定作用,而臭氧-活性炭深度处理工艺对水中雌激素的去除效果明显,去除率可达到100%,两种工艺对二恶英无明显去除效果。
A systematic study on hormonal activity in the water of Yellow River reservoir of Jinan which was the acceptor of South-to-north Water Transmission Project, and mountain reservoir was carried out. Using Chemical-Luciferase Gene Expression （CALUX）, four kinds of environmental endocrine disruptors inclu ding dioxins, estrogen, androgen and adrenaline were analyze＆ Results showed that both androgens and adrenaline concentrations were below the detection limits in source water of Jinan. The estrogen and dioxins were in the range of 0. 040-0. 250 E2 TEQ ng/L and 0. 009 0. 250 2,3,7,8-TCDD TEQ ng/L respectively. Water quality in mountainous reservoir was slightly better than that of the Yellow River reservoir. Kstrogen and dioxin levels were slightly higher in autumn and winter than in the spring and summer. Compared with water quality in reservoirs in other countries, dioxins level in reservoir water source of Jinan is higher but estrogen level was lower, and androgen and adrenaline pollution risk was smaller. Conventional water treatment process had a certain effect on the removal of estroger. However, its removal rate by ozone-activated carbon advanced treatment could reach 100% satisfyingly. None of two kinds of process had significant removal effect on dioxins.
