摘要: The viability of marine macrophytes being used as monitors heavy metal contamination in coastal zones was evaluated by analysis the concentration certain elements two brown algae species, Padina gymnospora and Sargassum stenophyllum, a seagrass Halodule wrightii. These species were collected Rio de Janeiro State regions, Sepetiba Bay, which has been brunt an environmental degradation process over last decades, Ribeira non-contaminated area. In addition, situ transplant experiments with P. between regions done. algal presented similar behavior regarding accumulation, indicating high concentrations Zn Cd Bay relation to wide distribution these metals along non seasonal temporal variation levels, this related inputs throughout into Bay. results show that is able accumulate studied short period time (one month) thus reflecting ambient bioavailability low plant release region. H. wrightii roots leaves main compartments accumulation found populations could reflect sediments.
