The following study presents the concentrations of 10 individual polycyclic aromatic hydrocarbons (PAHs) and the total concentration of PAHs (ΣPAHs) determined in soils of protected areas in Southern Poland (EU). The protected areas discussed here include 5 landscape parks and 5 nature reserves located in the Małopolska region. Surface soil samples were collected at 39 locations characterised by different natural conditions and different human pressure level. The samples were used to determine the contents of anthracene, benzo[a]pyrene, benz[a]anthracene, benzo[b]fluoranthene, benzo[k]fluoranthene, benzo[g,h,i]perylene, chrysene, dibenz[a,h]anthracene, indeno[1,2,3-cd]pyrene and naphthalene. These concentrations of individual PAHs ranged from < 0.005 to 6.34 mg/kg. When considering the legal regulations currently in force, this meant that permissible values were exceeded in 23% of the samples analysed, while increased concentrations were found in another 26% of the samples. The limit values were exceeded most in the case of benzo[b]fluoranthene and benzo[a]pyrene. This occurred with samples collected in the vicinity of transportation routes, mainly local roads. In the case of naphthalene and anthracene, the limit values were not exceeded. Increased or excessive PAHs concentrations do not occur in the vicinity of major industrial plants located near the boundaries of individual landscape parks, which indicates how these pollutants spread. The paper also points to the need to develop new legal solutions to improve the method for assessing PAHs concentrations and their impact on valuable natural areas.
本研究报告介绍了波兰南部受保护地区(欧盟)土壤中 10 种单体多环芳烃(PAHs)和总浓度(ΣPAHs)的浓度。这里讨论的受保护地区包括位于小波兰省的 5 个景观公园和 5 个自然保护区。在 39 个具有不同自然条件和不同人为压力水平的地点采集了表层土壤样本。使用这些样本来确定蒽、苯并[a]芘、苯并[a]蒽、苯并[b]荧蒽、苯并[k]荧蒽、苯并[g,h,i]苝、屈、二苯并[a,h]蒽、茚并[1,2,3-cd]芘和萘的含量。这些单体 PAHs 的浓度范围从<0.005 到 6.34 mg/kg。考虑到目前现行的法律规定,这意味着在分析的样本中,有 23%的样本超过了允许值,而另外 26%的样本则发现浓度增加。在苯并[b]荧蒽和苯并[a]芘的情况下,超过了限值。这发生在靠近交通路线的样本中,主要是当地道路。在萘和蒽的情况下,没有超过限值。在靠近位于个别景观公园边界附近的主要工业工厂的地方,不会出现增加或过度的 PAHs 浓度,这表明了这些污染物的传播方式。该论文还指出,需要制定新的法律解决方案,以改进评估 PAHs 浓度及其对有价值的自然区域的影响的方法。
