This is a second report of epidemiological and clinical investigation, related to the arsenic health problem, unique in the world, occurring in the city of Antofagasta, Chile. The arsenic problem originates in the chronic contamination of water supply in the city during 12 years. This phenomena, investigated clinically and epidemiologically and first reported in 1971, prompted the installation of a water treatment plant. This report aims to evaluate the working efficiency of the plant. The study was carried out through the examination of arsenic content in hair and nail clipping samples of the inhabitants of Antofagasta and the determination of this element in cultivated vegetables and carbonated beverages. Also a clinical study in school children, looking for cutaneous lesions attributed to arsenicism, was made. Results are encouraging. They reveal that contamination persists but in significantly lower levels.
这是一份关于砷健康问题的流行病学和临床调查的第二份报告，该问题在智利安托法加斯塔市出现，在全球范围内独一无二。砷问题源于该市供水长达12年的慢性污染。这一现象经临床和流行病学调查，于1971年首次报告，促使了一座水处理厂的建立。本报告旨在评估该厂的工作效率。该研究通过检测安托法加斯塔居民头发和指甲剪样本中的砷含量以及测定种植蔬菜和碳酸饮料中的该元素来进行。此外，还对学童进行了一项临床研究，以寻找归因于砷中毒的皮肤病变。结果令人鼓舞。结果显示污染仍然存在，但水平显著降低。
