Lake Tahoe is so full of microplastics that their concentration in its waters—5.4 plastic particles per cubic meter—is greater than the ...Microplastics have been found in surface waters of oceans, lakes, rivers, and streams. In the Great Lakes, microplastics have been proven to travel long distances from sites of origination to the lake surface and then onto lake shorelines because of their high mobility (Eriksen et al., 2013, Hoffman and Hittinger, 2016, Wagner et al., 2014).The lack of uniform specifications or standards on how microplastics can be detected makes it difficult to deal with the often invisible pollution. The data basis on current pollution in lakes, such as Lake Constance, is still incomplete. Research has detected microplastics in these waters, but what the actual contamination looks like is unknown.The abundances and properties of microplastics in the lakes from different areas largely varied. • Microplastic pollution was closely related to the local development level and economic structure. • The migration paths of microplastics in the inner and external limnic ecosystems were revealed. •

Freshwater microplastics research has focused on evaluating trends in quieter waters as well, including lakes, ponds, and wetlands (e.g., Bertoldi et al., 2021; Su et al., 2016; Wang et al., 2017). These still waters can be substantially affected by microplastic pollution present in contributing streams and rivers (Migwi et al., 2020).Algae can catch up to a trillion pieces of microplastics, according to a new study.
