Trace metal accumulation in marine macrophytes: Hotspots of coastal contamination worldwide

AbstractThis study compiles, from 155 peer review research articles, almost 23,000 estimates of trace metals (As, Cd, Co, Cr, Cu, Fe, Hg, Mn, Ni, Pb and Zn) contents in natural populations of marine macrophytes (seagrasses, chlorophytae, phaeophytae and rhodophytae) worldwide. The objective was to explore the distribution of these metals, to examine its trends of accumulation and to identify hotspots of coastal pollution. Our results point out phaeophytae as the group with the maximum accumulation capacity and tolerance to elevated concentrations of metals, and indicate that, despite of the geographic differences and local and regional influences, exist a similar atomic ratio of trace metals accumulation in the four groups of marine macrophytes regardless the species. The mapping of geographic distribution of metal accumulation in marine macrophytes identifies some coastal areas as hotspots of trace metal contamination. This work aims to provide a reference for futures studies.
