In view of the recent action in Marine Strategy Framework Directive, reconstructing the history of anthropogenic metal inputs and calculating the budgets for the northwestern part of the Italian Adriatic basin can provide a benchmark for comparison with new evidences and enlighten recent environmental changes. Among the metals, the attention was focused on Pb and Zn, as they provide the most significant anthropogenic signals. In 1988, areal distributions clearly identified the Po, Adige and Brenta rivers as the main sources of contaminants. The study area was divided in three compartments. The area in front of the Po delta represented a sink for metals but the accumulation of Zn and Pb integrated over the entire study area suggests an effective export throughout southern boundary. Most concentration-depth/year profiles in cores showed an upward increase from the Italian Unification (1861), with a still significant anthropogenic supply at the time of sampling.
鉴于海洋战略框架指令的近期行动，重建人为金属输入的历史，并计算意大利亚得里亚海西北部的预算，可以为与新证据进行比较提供基准，并阐明最近的环境变化。在这些金属中，重点关注铅和锌，因为它们提供了最显著的人为信号。1988 年，区域分布清楚地确定了波河、阿迪杰河和布伦塔河是污染物的主要来源。研究区域分为三个区室。波河三角洲前的区域是金属的汇，但整个研究区域的锌和铅的积累表明，南部边界的有效输出量很大。大多数核心的浓度-深度/年剖面显示出自意大利统一（1861 年）以来的上升趋势，在采样时仍有大量人为供应。
