Natural contamination with arsenic and other toxic trace elements was studied on a 50,000 km(2) area of the Pampean Plain in Argentina. The locations where natural sources of arsenic are considered to be of concern continue to grow, and include those associated with soils developed on loess or loessic sediments zones and transported volcanic materials sites. Contents of total arsenic, vanadium, chromium, iron and barium higher than those recommended as maximum allowable levels in drinking waters have been measured. In the case of arsenic, analyses of raw groundwaters yielded levels as high as 600 microg As/l. Reported data are discussed in connection with geological and environmental processes involved in ground water contamination.
对阿根廷潘帕斯平原50000平方公里的区域进行了砷及其他有毒微量元素的自然污染研究。被认为令人担忧的砷自然来源地点不断增加，包括那些与黄土或黄土质沉积物区域发育的土壤以及火山物质搬运地点相关的地方。已测量出总砷、钒、铬、铁和钡的含量高于饮用水中建议的最大允许水平。就砷而言，对原地下水的分析得出的含量高达600微克砷/升。结合地下水污染所涉及的地质和环境过程对报告的数据进行了讨论。
