Review on microplastic studies in Brazilian aquatic ecosystems

The microplastic studies in the world is increasing, reflecting concern about its effects on the ecosystem. The same happened in Brazil, especially in the last six years, but few places were monitored. Thus, a literature review was conducted to collect data on microplastic pollution in Brazilian aquatic ecosystems, analyzing this pollutant in samples of sandy sediments, plankton and other invertebrates and vertebrates. As results, we highlight the following points: 56% of the studies were published in the Journal Marine Pollution Bulletin; collaborative and independent studies presented the same number; the Brazilian Northeast and Southeast were the most studied areas; the investigation of microplastics associated with biota was highlighted (46% of studies); only one study was conducted in a freshwater environment. Based on this review, we identified the subjects that would be more studied in researches in the Brazilian environment about microplastics. The monitoring of microplastics must be continuous to verify the impacts of this material and extend the understanding of this problem.
