The polycyclic aromatic hydrocarbon (PAH) contamination of urban, agricultural and forest soil samples was investigated from samples obtained in the surroundings of Valasske Mezirici. Valasske Mezirici is a town located in the north-east mountainous part of the Czech Republic, where a coal tar refinery is situated. 16 PAHs listed in the US EPA were investigated. Organic oxidizable carbon was also observed in the forest soils. The PAH concentrations ranged from 0.86-10.84 (with one anomalous value of 35.14) and 7.66-79.39 mg/kg dm in the urban/agricultural and forest soils, respectively. While the PAH levels in the urban/agricultural soils are within the range typically found in industrialized areas, the forest soils showed elevated PAH concentrations compared to other forest soils in Western and Northern Europe. The PAH concentrations and their molecular distribution ratios were studied as functions of the sample location and the meteorological history. The soils from localities at higher altitudes above sea level have the highest PAH concentrations, and the PAH concentrations decrease with increasing distance from the town.
从捷克共和国东北部山区瓦尔塔梅日利采镇附近采集的城市、农业和森林土壤样本中，研究了多环芳烃（PAH）的污染情况。瓦尔塔梅日利采镇坐落于一家煤焦油精炼厂附近。研究了美国环保署列出的 16 种多环芳烃。在森林土壤中还观察到了有机可氧化碳。城市/农业土壤中的 PAH 浓度范围分别为 0.86-10.84（一个异常值为 35.14）和 7.66-79.39mg/kg dm，森林土壤中的 PAH 浓度与西欧和北欧的其他森林土壤相比有所升高。城市/农业土壤中的 PAH 水平处于工业化地区常见的范围内，而森林土壤中的 PAH 浓度则高于其他森林土壤。研究了 PAH 浓度及其分子分布比与样本位置和气象历史的关系。海拔较高地区的土壤中 PAH 浓度最高，并且随着与城镇距离的增加，PAH 浓度逐渐降低。
