| 摘 要： | 通过对2016年三峡库区干支流18个采样点水体和底泥中16种多环芳烃(PAHs)和6种邻苯二甲酸酯类(PAEs)污染物浓度的时空分布特征和来源进行分析,得出如下结论:三峡库区2016年水体和底泥中ΣPAHs分别为3.9~107.6 ng/L(均值为39.9 ng/L)和267.9~1018.1 ng/g(均值为490.9 ng/g),ΣPAEs分别为122.4~2884.7 ng/L(均值为848.1 ng/L)和192.9~3473.4 ng/g(均值为1253.35 ng/g).水库水体和底泥中PAHs和PAEs均表现出显著的时空分布特征.干支流水体ΣPAHs平均浓度均为放水期(6月)高于蓄水期(12月),干流底泥ΣPAHs平均含量在蓄水期高于放水期.干流水体中ΣPAEs平均浓度在蓄水期显著高于放水期,底泥中ΣPAEs平均含量为放水期高于蓄水期.库区水体中的PAHs以2~3环和4环为主,底泥中以4环和5~6环为主.水体和底泥中PAEs均以邻苯二甲酸(2-乙基已基)酯和邻苯二甲酸二正丁酯为主.库区水体中PAHs的主要来源为焦化或煤焦油挥发、石油源及燃料的中低温燃烧;底泥中PAHs主要来源为煤和生物质燃烧以及石油.水体和底泥中的PAEs主要来源于塑料和重化工工业以及生活垃圾.
