Abstract This work discusses the results of a geochemical survey conducted in the Salerno urban area to determine the sources patterns of major, minor, trace and ultra-trace elements in soils. In particular, the study focused on elements that are potentially toxic and listed in the environmental Italian legislation (D.L. 152/06), in order to effectively monitoring an important aspect of environment health. A total of 151 topsoil samples were collected, air-dried and sieved ( The study revealed that major and minor elements (Al, Ca, Fe, K, Mg, Na, P, S and Ti) have a perfectly natural distribution with no discernible association to any human activity or presence. In contrast, many trace and ultra-trace elements (Ag, As, Au, Ba, Be, Cd, Co, Cr, Cu, Hg, Mn, Mo, Ni, Pb, Pd, Pt, Rh, Sb, Sn, Tl, V and Zn) show anomalous concentration values located almost exclusively in highly inhabited areas, industrial sites and along high traffic roads. Other trace and ultra-trace elements (B, Bi, Ga, La, Sc, Se, Sr, Te, Th, Tl, U and W) show concentrations compatible with the natural background levels. Some potentially toxic elements (e.g. Pb and Zn) reach concentration levels tens of times higher than the legal limits in the busiest areas of the city. Exposure to high concentrations of these contaminants may cause health problems to people living in these zones.

萨勒诺（意大利）的城市土壤污染：土壤中主要、次要、微量和超微量元素的浓度和模式

摘要 这项工作讨论了在萨勒诺市区进行的地球化学调查的结果，以确定土壤中主要、次要、痕量和超痕量元素的来源模式。特别是，该研究侧重于意大利环境立法 (DL 152/06) 中列出的潜在有毒元素，以便有效监测环境健康的一个重要方面。共收集、风干和筛分 151 个表土样品（研究表明，主要和次要元素（Al、Ca、Fe、K、Mg、Na、P、S 和 Ti）具有完美的自然分布，没有可辨别的与任何人类活动或存在有关。相反，许多微量和超微量元素（Ag、As、Au、Ba、Be、Cd、Co、Cr、Cu、Hg、Mn、Mo、Ni、Pb、Pd、Pt , Rh, Sb, Sn, Tl, V 和 Zn) 显示的异常浓度值几乎完全位于人烟稠密的地区、工业场所和交通繁忙的道路沿线。其他痕量和超痕量元素（B、Bi、Ga、La、Sc、Se、Sr、Te、Th、Tl、U 和 W）显示出与自然背景水平兼容的浓度。在城市最繁忙的地区，一些潜在有毒元素（例如铅和锌）的浓度水平比法定限制高出数十倍。接触高浓度的这些污染物可能会给生活在这些地区的人们带来健康问题。Pb 和 Zn) 的浓度水平比该市最繁忙地区的法定限值高出数十倍。接触高浓度的这些污染物可能会给生活在这些地区的人们带来健康问题。Pb 和 Zn) 的浓度水平比该市最繁忙地区的法定限值高出数十倍。接触高浓度的这些污染物可能会给生活在这些地区的人们带来健康问题。
