RESUMO:

Microplastics are spread in oceans and represent one of the main concerns of researchers and managers of marine environments. This systematic review investigates the accumulation of microplastics in filter feeders, focusing on the potential relationship between the mechanism of feeding and accumulation rates. This is the first systematic review comparing the accumulation of microplastic in benthic filter feeders that use different mechanisms of filter feeding. The review utilized the PICOS Criteria to determine the inclusion of studies. Rayyan® software was employed for screening the articles, and data extraction was subsequently carried out. The review followed a well-structured protocol by PRISMA 2020 guidelines to guarantee methodological rigor and minimize biases. Exhaustive research in the Web of Science and Scopus databases identified 138 relevant articles. After carefully evaluating and applying inclusion and exclusion criteria, 42 eligible studies were considered. A word cloud analysis was conducted to illustrate the most frequent keywords and their co-occurrence. Additionally, bar plots and vioplots effectively depicted the concentration of microplastics within each taxonomic group. The accumulation pattern of microplastics among different species was visually represented using tileplots. There was a high heterogeneity in the studies included (I2>95%) and a notable increase in publications in recent years, although these studies are concentrated in a limited number of countries. Despite methodological inconsistencies that precluded meta-analysis, a narrative synthesis provided information on the complex relationship between microplastic accumulation and feeding behavior. The highest amounts of microplastics accumulated (average) were recorded in Indonesia (1054 avg. particles/study), Norway (881 avg. particles/study), Panama (448 avg. particles/study), China (219.25 avg. particles/study), and Netherlands (116 avg. particles/study). Most publications report microplastics in mollusks (oysters, mussels, and clams), and Mytilus was the taxa with most studies. The maximum values of microplastic accumulation occurring in Polychaetes (1 to 880 items g–1 WW) were observed. Although it is possible to establish relationships between feeding mechanisms and microplastic accumulation, the use of different methodologies in microplastic studies prevents the comparison of results, leading to an urgent call for the standardization of methods in microplastic studies in marine organisms.
