【摘要】 采用气相色谱-质谱法(GC-MS)对长白山圆池雨养泥炭表层16种优控多环芳烃(PAHs)污染物进行分析并对其来源进行了探讨.结果表明,该区表层PAHs含量为1404~1936ng/g,PAHs以2~3环为主,苯并(a)芘等强致癌性化合物均有不同程度的检出.结合菲/蒽、荧蒽/芘等参数值分析,推测该区泥炭表层PAHs主要来源于化石燃料的不完全燃烧,生物合成作用产生的PAHs也有一定的贡献.对泥炭表层单体PAH与总PAHs回归分析表明,苊烯、荧蒽、芘可以作为泥炭表层标志性PAHs污染物.更多还原

【Abstract】 Adopting gas chromatography-mass spectrometer (GC-MS) on Changbai Mountains Yuanchi ombrotophic peat,16 kinds of priority controlled polycyclic aromatic hydrocarbons (PAHs) pollutants were analyzed. This region surface layer PAHs content was 1404 to 1936ng/g, PAHs of 2~3 rings were the main. The strong carcmogenic compounds as benzo(a)pyrene were all detected in combining phenanthrene/anthracene, fluoranthene/pyrene et parameter values analysis. It was inferred that this region peat surface layer PAHs source was mainly fossil fuel uncompleted combustion. Biosynthetic action produced PAHs had also definite contribution. The regression analysis on peat surface layer single body PAH and total PAHs showed that acenaphthylene,fluoranthene and pyrene could be used as peat surface layer sign property PAHs pollutants.更多还原
