Investigation has been carried out in the vicinity of an aluminum smelter located in the industrialized town of Konin. Concentrations of 14 polycyclic aromatic hydrocarbons (PAHs) were determined in grass, spruce needles, and soil collected in the period of the smelter operation and several years after its closing. Significant changes in the quantity of PAHs and their profiles observed in the two measuring periods, stressing the importance of aluminum production with regard to PAH emission. It was confirmed by very high values of the carcinogenic potential (CP) found for PAHs accumulated in grass and soil when compared to the values found in urban and remote sites. PAH ratio rates used as a tool for identifying emission sources showed a pyrogenic origin of PAHs in both periods; the ratios in the period of the smelter running activity were similar to those found in other studies carried out near aluminum smelters. Grass turned out to be a good biomonitor of PAHs similarly to commonly used leaves of various tree species. The use of four age classes of spruce needles, some of which were subjected to emission from the smelter, showed that such approach could serve as an analysis tool for describing retrospective pollution.
研究在位于工业化城镇科宁的一家铝冶炼厂附近进行。在冶炼厂运营期间和关闭数年后，采集了草、云杉针叶和土壤样本，并测定了其中 14 种多环芳烃 (PAHs) 的浓度。在两个测量期内观察到 PAHs 的数量和分布发生了显著变化，这强调了铝生产对 PAH 排放的重要性。与城市和偏远地区相比，在草和土壤中积累的 PAH 的致癌潜力 (CP) 值非常高，证实了这一点。用作识别排放源的 PAH 比值显示两个时期的 PAH 均来自于高温燃烧源；在冶炼厂运行期间的比值与在其他靠近铝冶炼厂进行的研究中发现的比值相似。草和云杉针叶都可以作为 PAHs 的生物监测器，与常用的各种树种的叶子类似。使用四个年龄组的云杉针叶，其中一些受到冶炼厂排放的影响，表明这种方法可以作为描述回溯污染的分析工具。
