The emission of chemicals into the environment has increased in a not negligible way as a result of the phenomenon of globalization and industrialization, potentially also affecting areas always considered as "uncontaminated". In this paper, five "uncontaminated" areas were analyzed in terms of the presence of polycyclic aromatic hydrocarbons (PAHs) and heavy metals (HMs), comparing them with an "environmental blank". Chemical analyses were carried out using standardized protocols. The 'environmental blank' results revealed the presence of Cu (<64.9 μg g), Ni (<37.2 μg g), and Zn (<52.6 μg g) as HMs and fluorene (<17.0 ng g) and phenanthrene (<11.5 ng g) as PAHs. However, regarding the results of the pollution status of the areas under study, fluorene (#S1, 0.34 ng g; #S2, 4.3 ng g; #S3, 5.1 ng g; #S4, 3.4 ng g; #S5, 0.7 ng g) and phenanthrene (#S1, 0. 24 ng g; #S2, 3.1 ng g; #S3, 3.2 ng g; #S4, 3.3 ng g; #S5, 0.5 ng g) were found in all areas, while the other PAHs investigated were detected at a concentration averaging less than 3.3 ng g. HMs were found in all of the investigated areas. In particular, Cd was detected in all areas with an average concentration of less than 0.036 μg g, while Pb was absent in area #S5, but present in the other areas with an average concentration of less than 0.018 μg g.
由于全球化和工业化现象，化学物质向环境中的排放以不可忽视的方式增加，这也可能影响到一直被视为“未受污染”的地区。本文分析了五个“未受污染”地区的多环芳烃（PAHs）和重金属（HMs）的存在情况，并与一个“环境空白”进行了比较。化学分析采用标准化方案进行。“环境空白”结果显示，作为重金属的铜（<64.9 μg/g）、镍（<37.2 μg/g）和锌（<52.6 μg/g）以及作为多环芳烃的芴（<17.0 ng/g）和菲（<11.5 ng/g）存在。然而，关于所研究地区的污染状况结果，在所有地区都发现了芴（#S1，0.34 ng/g；#S2，4.3 ng/g；#S3，5.1 ng/g；#S4，3.4 ng/g；#S5，0.7 ng/g）和菲（#S1，0.24 ng/g；#S2，3.1 ng/g；#S3，3.2 ng/g；#S4，3.3 ng/g；#S5，0.5 ng/g），而所研究的其他多环芳烃的检测浓度平均低于3.3 ng/g。在所有调查地区都发现了重金属。特别是，在所有地区都检测到了镉，平均浓度低于0.036 μg/g，而在#S5地区没有检测到铅，但在其他地区存在，平均浓度低于0.018 μg/g。
