摘要:应用色谱.质谱联用技术,鉴定了石龙区地表水悬浮颗粒物(颗粒相)中的多环芳烃化合物(PAHs),分析了其在不同水体中的分布特征,
并应用PAHs特征性比值对其进行了源解析.结果表明,共鉴定出除苊和二氢苊之外的l4种美国EPA优控PAHs.水塘水、河流水颗粒相中
PAHs含量远高于矿井水,且毒性等效浓度也较高,尤其是水塘水表现出更为严重的PAHs积累态势.源解析认为,矿井水颗粒相PAHs主要是
其 自身携带煤层中的粉尘所致;水塘水颗粒相PAHs以焦化飞灰、燃煤烟尘等燃烧产物输入为主:河流水颗粒相PAHs则不仅仅是由矿井水
携带注入,大气颗粒物的干湿沉降及电厂、洗煤厂等工业废水也是重要的输入源.
