This study compared the accumulation of 16 polycyclic aromatic hydrocarbons (PAHs) in samples of the lichen Evernia prunastri exposed for 3 months in and around an industrial area of S Italy with that in co-located passive gas-phase air samplers. The results showed a strong linear correlations (R=0.96, P<0.05) between total PAHs in lichens and in passive samplers, clearly indicating that lichen transplants may provide direct quantitative information on the atmospheric load by total PAHs, allowing translation of lichen values into atmospheric concentrations. To the best of our knowledge this is the first study reporting such a correlation with gas-phase passive air samplers.
本研究比较了在意大利南部一个工业区及其周边暴露3个月的地衣扁枝衣样本中16种多环芳烃(PAHs)的积累情况与同地点被动气相空气采样器中的积累情况。结果表明,地衣和被动采样器中总PAHs之间存在很强的线性相关性(R = 0.96,P < 0.05),这清楚地表明地衣移植可以提供关于大气中总PAHs负荷的直接定量信息,从而将地衣中的数值转化为大气浓度。据我们所知,这是第一项报道与气相被动空气采样器存在这种相关性的研究。
