Total dissolved Cu, Zn, Pb and Cd concentrations, speciation, fluorescence of organic matter and toxicity for sea urchin development have been studied during three years in water samples of three of the most industrialized harbours in North Coast of Spain: Vigo, Bilbao and Pasajes. Total metal concentrations were below 0.4 nM for Cd and generally below 2 nM for Pb. Zn and Cu levels were higher (2.8-9 nM Cu and 15-234 nM Zn) and denoted an anthropogenic enrichment. Ligand concentrations were usually between 50 and 200 nM for Cu and between 6 and 80 for Pb and Zn. Organic matter and speciation analysis yielded complementary information to characterize the samples, but no correlation was present between the parameters calculated by both methods. Samples were tested for toxicity with sea urchin embryo bioassay and three samples were toxic but the toxicity could not be explained with the metal levels here measured.
在三年的时间里，对西班牙北海岸三个工业化程度最高的港口（维哥、毕尔巴鄂和帕萨耶斯）的水样进行了总溶解态 Cu、Zn、Pb 和 Cd 浓度、形态、有机物荧光和对海胆发育的毒性研究。Cd 的总金属浓度低于 0.4 nM，而 Pb 通常低于 2 nM。Zn 和 Cu 的水平较高（2.8-9 nM Cu 和 15-234 nM Zn），表示人为富集。配体浓度通常在 50 和 200 nM 之间，对于 Cu，在 6 和 80 nM 之间，对于 Pb 和 Zn。有机物和形态分析提供了补充信息来描述样品，但两种方法计算的参数之间没有相关性。用海胆胚胎生物测定法对样品进行了毒性测试，有三个样品是有毒的，但毒性不能用这里测量的金属水平来解释。
