Sediments from 35 beaches along the Asturian coastline in the north of Spain were studied. Geochemical analyses were conducted to assess the distribution of metal(oid) concentrations on the coast. Samples were correlated by a cluster analysis based on their geochemical concentrations, showing three different groups. Group 1 and Group 2 were composed of the samples of the occidental and oriental beaches, respectively, while Group 3 was formed by the beaches that are in the area of influence of one of the main harbours in the north of Spain where there is an established metal and chemical industry. These associations may explain the origin of the metal concentrations in the coastline. Both geological and anthropic sources generated geochemical anomalies in the sediment concentrations that sometimes surpassed quality OSPAR criterion.

研究了西班牙北部阿斯图里亚斯海岸线沿线35个海滩的沉积物。进行了地球化学分析以评估海岸上的金属（类固醇）浓度分布。通过基于地球化学浓度的聚类分析将样品关联起来，显示出三个不同的组。第1组和第2组分别由西方和东方海滩的样本组成，而第3组由西班牙北部主要港口之一影响范围内的海滩组成。金属和化学工业。这些联系可以解释海岸线中金属浓度的来源。地质和人为源都产生了有时超过质量OSPAR标准的沉积物浓度的地球化学异常。
