SUMMARY:

Marine ecosystems, especially those close to urban centers, are used for resource exploitation (portuary activities, tourism, fisheries, shellfish extraction) and often receive the residues of human activities. In addition to other types of pollution such as plastic, coastal environments are often impacted by sewage. In contact with sea water, sewage pollution may dissipate and create various gradients, such as in salinity, temperature, pH, nutrients, and heavy metals, which may impact the benthic fauna, including organisms such as mussells, which are indicators of environmental quality. A variety of methods has been used to detect the effects of pollution on mussels. The objective of this review was to analyze studies which assessed the effects of pollution by sewage and hydrocarbons on mussels of tropical rocky shores, assessing the most commonly used methods for bivalves as bioindicators. We searched in well-known databases and used computational algorithms to aid with the definition of keywords. We found a total of 514 manuscripts. After applying the exclusion criteria, 41 papers were selected for detailed assessment and 33 were included in the final analysis. Most of the methods used focused on physicochemical analyses of the concentration of toxic substances in the bivalves' tissues and shells. Ecological methods, focused on the composition of bivalve assemblies and variation in species composition with coastal pollution, were less frequent. Studies on ecological aspects of bivalves may complement the chemical studies and act as robust alternatives in studies of bioindicators. Thus, we recommend that more ecological studies, focused on bivalve populations and communities, be done in tropical regions.
