In 2005, the concentrations of various metals and organic pollutants were analyzed in soils collected in different areas of Tarragona (Catalonia, Spain), where an important chemical/petrochemical complex is located. The levels of seven elements (As, Cd, Cr, Hg, Mn, Pb and V), as well as those of polychlorinated biphenyls (PCBs), polychlorinated naphthalenes (PCNs) and polycyclic aromatic hydrocarbons (PAHs) were determined in soils, and compared with those obtained in a background study carried out in 2002. Only Cd and Pb showed significant higher concentrations in the petrochemical zone, while no significant differences were found for the remaining elements. In turn, vanadium was the only element showing a significant increase in the concentration between 2002 and 2005. With regard to the organic pollutants, no significant differences were found according to the area of sampling. However, an increase in naphthalene levels was observed during the period 2002-2005 in soils of the chemical and petrochemical areas. According to the present results, it is suggested that the levels of vanadium must be periodically monitored to assure that the important industrialization of Tarragona does not mean health risks for the population living near the complex.
2005年，对位于西班牙加泰罗尼亚塔拉戈纳不同区域采集的土壤中的各种金属和有机污染物浓度进行了分析，该地有一个重要的化学/石化综合企业。测定了土壤中七种元素（砷、镉、铬、汞、锰、铅和钒）以及多氯联苯（PCBs）、多氯萘（PCNs）和多环芳烃（PAHs）的含量，并与2002年进行的背景研究结果进行了比较。只有镉和铅在石化区的浓度显著更高，而其余元素未发现显著差异。反过来，钒是2002年至2005年期间唯一浓度显著增加的元素。关于有机污染物，根据采样区域未发现显著差异。然而，在2002 - 2005年期间，化学和石化区土壤中的萘含量有所增加。根据目前的结果，建议定期监测钒的含量，以确保塔拉戈纳的重要工业化不会对居住在该综合企业附近的居民造成健康风险。
