摘要
运用ＧＣ／ＭＳ对上海南汇淤泥质潮滩夏秋两个季节表层沉积物中的有机污染物多环芳烃作定性和定量分析。结果表明，该区多环芳烃总浓度最高达０．８２９μｇ／ｇ；个别组分已超出检测限达３～７倍，它们在秋季潮滩以及夏季中潮滩其浓度值及在ＰＡＨｓ总量中所占的百分比比重较大，已成为ＰＡＨｓ有机污染物高浓度区。
猅he results of qualitative and quantitative analyses on the Polycyclic Aromatic Hydrocarbons (PAHs) in surface sediments of tidal mud flat in the summer and the fall from Nanhui,Shanghai, show that the total PAHs concentration is up to 0.829μg/g.The individual component concentration is 3～7 times more than the monitoring limit and there is high content and percentage in total PAHs in the fall tidal flat and the summer mid tidal flat,thus becoming PAHs polltants of the high sediment concentration levers in this region.
