The aim of this study was to assess the levels of heavy metal pollution in the clay/silt fraction (<63 μm fraction) of marine sediments from Quintero Bay, Chile. For this, sediment samples were collected from 14 sites from the bay and analyzed for major and minor element determination. The metal concentrations found suggest an anthropogenic origin related with Cu, Se, Mo, As, Sb and Pb. The mineralogical characteristics of the samples were determined by XRD and selected samples were examined by SEM to determine morphological differences. The results showed heavy metal-bearing particles such as Cu, Zn, As and Pb, which are most likely associated with by the copper smelter.
本研究旨在评估智利昆特罗湾海洋沉积物中粘土/粉砂（<63μm 级分）中的重金属污染水平。为此，从该湾的 14 个地点采集了沉积物样品，并对其进行了主要和次要元素的测定。所发现的金属浓度表明与 Cu、Se、Mo、As、Sb 和 Pb 有关的人为来源。通过 XRD 确定了样品的矿物学特征，并通过 SEM 检查了选定的样品，以确定形态差异。结果表明存在含重金属的颗粒，如 Cu、Zn、As 和 Pb，这些颗粒很可能与铜冶炼厂有关。
