中文摘要：

采用气相色谱（GC-FID）检测技术，对杭州城区水体以及黄颡鱼（Pelteobagrusvachelli）肌肉和脑等可食性组织中5种PAEs类化合物进行检测，确定杭州城区水体中PAEs分布特征，并分析了PAEs在黄颡鱼肌肉和脑中含量随时间动态变化规律。研究结果表明，杭州城区水体中5种PAEs化合物含量均较高，但每种化合物含量差异较大，其中DEHP含量在不同水域中含量均最高。黄颡鱼体内残留检测结果显示，5种PAEs类化合物在黄颡鱼肌肉和脑等可食性组织中均有分布，其中脑和肌肉中的消除半衰期处于17.33—32．54h之间。结果表明，PAEs在杭州城区不同水体中广泛分布，在鱼体肌肉和脑等可食性组织中消除较缓慢。

英文摘要：

A GC-FID method was established for simultaneous determination of five PAEs chemicals in water and in fish tissues, which was used to study the PAEs distribution characteristics in water of Hangzhou city and elimination rule in darkbarbel catfish, Pelteobagrus vachelli. And the detection results showed that there were significant differences about PALEs chemicals distribution in different districts of Hangzhou and the content of DEHP was the highest. Then five PAEs chemicals were widely distributed in edible tissues of darkbarbel catfish such as muscle and brain. And their elimination half-times lie between 17.33h and 32.54h in muscle and brain. Therefore, all the results showed that five PAEs chemicals were widely distributed in the different areas of Hangzhou District and slowly eliminated from darkbarbel catfish.
