摘要:
多环芳烃(PAHs)是极具生态和健康风险的持久性有机污染物,具有长期残留性、生物蓄积性和很强的三致效应。为研究江苏省南京市常见绿化树种叶片PAHs含量水平以及其与叶片特征的关系,通过GC-MS测定树种叶片中PAHs含量并分析其与叶片特征(叶蜡含量、气孔密度、比叶面积)之间的关系。结果表明:洒金桃叶珊瑚叶片累积PAHs的能力最强(1.10 mg/kg),香樟累积能力最弱(0.22 mg/kg)。NaP、Phe、Fla、B(b)F是叶片主要的PAHs组分,叶片PAHs以二环、三环、四环为主,占总PAHs的70% 以上。在海桐、黄杨、红叶石楠、洒金桃叶珊瑚、桂花和八角金盘叶片中,叶片PAHs含量与叶蜡含量呈显著正相关,与气孔密度之间未发现显著相关性;除了八角金盘,5种树种叶片PAHs含量与比叶面积呈显著负相关;表明叶蜡含量与比叶面积是影响叶片PAHs含量的重要因素。研究结果可以为城市绿化树种的选择和配置提供科学参考。
