Microplastics in lakes

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.

We found 12,442 anthropogenic microparticles across 212 fish (8 species) from nearshore Lake Ontario, 943 across ...Apr 15, 2019 · Lakes may serve as the major sink of microplastics in freshwater ecosystems, since plastic debris could be continuously accumulating and preserved over a prolonged period of time. On the other hand, due to the higher reserves of microplastics, lakes could also become important sources of microplastics for the downstream watersheds. Like microplastics in other lakes of the world, those in the lakes in the Qinghai-Tibet Plateau mainly include organic polymers PA, PET, PE, and PP and are primarily in the shape of fibers and fragments. The microplastic pollution of lacustrine sediments in the Qinghai-Tibet Plateau is affected by natural changes and by human activities, and ...Lake Lanier covers several towns and up to 50,000 acres of what was once prime farm land.

Dec 1, 2020 · 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).
