| 摘 要： | 为了解辽河源头区典型支流——条子河四平段表层水体中多环芳烃(PAHs)的污染特征,分别于丰水期、平水期和枯水期采集条子河10个代表性断面的上覆水水样,测定了样品中16种优控PAHs的质量浓度、分析了其时空分布和来源,并对其生态风险进行了评价。结果表明:条子河表层水体中总PAHs的质量浓度(∑PAHs)范围为319.8~3 715.9 ng/L,平均值为1 476.0 ng/L,PAHs的组成以2~3环为主,占∑PAHs总量的53.1%~81.0%,5~6环的PAHs均未检测出。不同水期间,∑PAHs均值的大小顺序为:枯水期(2 035.0 ng/L)平水期(1 272.5 ng/L)丰水期(967.9 ng/L)。空间分布上,∑PAHs的检测最高值(3 715.9 ng/L)和平均浓度最大值(3 194.8 ng/L)均出现在位于四平市城区出境断面(汇合口)处。PAHs主要来源是石油、草木、煤炭的混合燃烧。条子河表层水体中苯并[a]芘的当量为5.1~36.1 ng/L,高于国家地表水环境质量标准值,条子河表层水体中PAHs存在一定的生态风险。
