To contribute to establishing a historical baseline for future evaluations of the environmental quality of the Ría de Vigo (NW Spain), we report metal contents determined in eight gravity cores obtained at representative locations in 1990 - before the installation of any wastewater treatment plants - and in fractions thereof that were obtained by the BCR sequential extraction method. The results suggest that early diagenesis had been influenced by both hydrodynamic conditions and organic matter input (the latter especially in areas devoted to mariculture), and that anthropogenic inputs had also affected the concentrations and between-fraction distribution of Cu, Pb, Zn and other metals in surficial sediments.
为了为未来评估维哥湾（西班牙西北部）的环境质量建立历史基线，我们报告了 1990 年在有代表性的地点获得的八个重力岩芯中测定的金属含量-在安装任何废水处理厂之前-以及通过 BCR 顺序提取方法获得的这些岩芯的部分。结果表明，早期成岩作用受到水动力条件和有机质输入的影响（后者在专门从事海水养殖的地区尤为明显），人为输入也影响了表层沉积物中 Cu、Pb、Zn 和其他金属的浓度和分馏分布。
