Abstract

One of the several environmental consequences of urbanization and anthropic activity in the surroundings of Guanabara Bay is the increasing entry of different pollutants into its waters. For instance, microplastics, which have a high concentration in the estuary and pose risks to living beings inserted in this ecosystem, including humans, thus requiring the attention of decision-makers in the region for actions to control and mitigate plastic pollution. The present study aimed to evaluate the main sources of microplastic pollution in Guanabara Bay (Rio de Janeiro, Brazil), based on a bibliographic survey on the occurrence, distribution, abundance and diversity of them in the estuary that allowed the definition of the most common classes in the study area, composed mainly of fibers, fragments and films. The sources of recurrent plastic micropollutants in the bay may be associated with the precarious sanitation infrastructure in the region, from the conditions of the sanitary effluents released, to the inadequate disposal and management of solid waste that allows the runoff of plastic pollutants through urban drainage, as well as the economic activities developed in the region, such as industries, port and maritime activities, and traditional fishing and aquaculture. It is expected that this study can support, in future research, the implementation of action plans with programs and projects to monitor and reduce the entry of plastic debris into Guanabara Bay and other aquatic environments.
