| 摘 要： | 为揭示松花江干支流表层沉积物中邻苯二甲酸酯类(phthalate esters,PAEs)的空间分布特征及其生态风险状况本文利用气相色谱三重四级杆质谱联用仪(GC-MS)对松花江干支流表层沉积物中6种PAEs的含量分布和组成特征进行了分析,并采用商值法和环境风险水平(ERL)法对其生态风险状况进行评价.结果表明:①松花江干支流沉积物6种邻苯二甲酸酯(∑_6PAEs)含量范围(以干重计)为6 832.5～36 298.9ng·g~(-1)(平均值为18388.6ng·g~(-1)),邻苯二甲酸(2-乙基己基)酯(DEHP)和邻苯二甲酸二丁酯(DBP)为主要组分,干流点位∑_6PAEs含量(6 832.5～36 298.9 ng·g~(-1),平均值为18 616.9ng·g~(-1))与支流点位∑_6PAEs(10 367.6～26 593.3ng·g~(-1),平均值为18 264.1ng·g~(-1))差异不显著(P0.05),支流点位各PAEs单体含量与干流点位差异不大.从上游到下游干支流∑_6PAEs含量呈现先降后升的趋势.农业自然区域∑_6PAEs平均含量(18 677.5 ng·g~(-1))与城市工业区域(18 063.7 ng·g~(-1))相近(P0.05),DBP和DEHP是两区域内的主要PAEs两者平均值贡献率高达98%以上.②松花江干支流表层沉积物中∑_6PAEs主要来源于人类日用品、农业生产以及含有增塑剂的工业生产.③松花江表层沉积物中DMP和BBP对水生生物无生态风险,DEP具有低水平生态风险,而DEHP和DBP对水生生物具有高生态风险.
