| 摘 要： | 为调查输水期于桥水库流域水中多环芳烃(PAHs)的分布特征,采用气相色谱-质谱法对该区16种US EPA优先控制的PAHs进行了分析,并对PAHs的健康风险和生态风险进行了评估.结果表明,在18个点位采集的水样中均有PAHs检出,且上游水域和库区PAHs组分和浓度均存在着显著差异.上游水域水体(除洒河大桥点位外)中的PAHs以2~3环为主,其百分比介于86%~95%,ΣPAHs浓度介于13.7~104.1 ng·L~(-1)间,其中大黑汀水库渔业养殖密集区水体中PAHs污染水平较高;库区水体中低环数和高环数PAHs含量相当,ΣPAHs浓度介于1.6~3 512.5 ng·L~(-1)间,其中库区北岸水中PAHs浓度最高.Flu/Pyr、Fla/(Fla+Pyr)比值分析表明,于桥水库流域PAHs主要来自村镇居民燃煤供暖、生物质燃烧.分别采用US EPA健康风险评价模型和Kalf等使用的商值法对PAHs的饮水致癌风险和生态风险进行了评估,结果显示,库区水体的饮水致癌风险水平超过了10-6,以及库区Ba]A、Bk]F、Bap的商值(实际浓度/最大允许参考浓度)也均大于1,说明库区水体PAHs引发的致癌风险和生态风险均应当引起重视.
