To assess environmental conditions along the coast of northern Chile, 457 sediment samples were collected between 22° S and 28° S in order to evaluate the Cu, Zn, Pb, Ni, V, Cd, As and Al content as well as its corresponding relationship to nearby anthropogenic activities. In general, the results of most metals showed that bays without industrial activity accumulate lower concentrations of contaminant elements in the sediments and thus mostly represent natural conditions. The highest Cu, Pb and V levels were measured in coastal zones were different industrial mining activities have been developed during the last decades. Results of different indices of environmental evaluation and ecological impact suggest that, metal content of sediments from pollution-free zones characterized by similar oceanographic and geological conditions to those under study, would be the most appropriate background level for assessing the anthropogenic impact on coastal areas of northern Chile.
为了评估智利北部沿海的环境状况，在 22°S 至 28°S 之间采集了 457 个沉积物样本，以评估 Cu、Zn、Pb、Ni、V、Cd、As 和 Al 的含量及其与附近人为活动的相应关系。总的来说，大多数金属的结果表明，没有工业活动的海湾在沉积物中积累的污染物元素浓度较低，因此主要代表自然条件。在过去几十年中开展了不同工业采矿活动的沿海地区，Cu、Pb 和 V 的含量最高。环境评价和生态影响的不同指数的结果表明，在与研究区域具有相似的海洋和地质条件的无污染区域，沉积物中的金属含量将是评估人为因素对智利北部沿海地区影响的最合适的背景水平。
