Abstract
Semi-enclosed bays are vulnerable to heavy metal accumulation. This study evaluated the spatial distribution of cadmium (Cd) in Bamen Bay using ICP-MS. Vertical profiles including the surface microlayer (SML), surface water, and bottom water were analyzed. Cd concentrations significantly decreased from the inner (0.22-0.29 μg/L) to the outside bay (0.10-0.14 μg/L). The SML exhibited strong Cd enrichment (Enrichment Factor: 1.20-1.48), largely driven by total organic carbon (TOC) complexation. This study highlights the critical role of the surface microlayer in heavy metal accumulation.
