Microplastics in lakes

Microplastics (MPs) are physical anthropogenic pollutants and their ability to act as contaminant vectors in biological matrices is of serious ecosystem and human health concern.

Introduction. Microplastics are generally characterised as water-insoluble, solid polymer particles that are ≤5 mm in size (Bergmann et al., 2015).A formal definition for the lower size boundary does not exist, but particles below 1 μm are usually referred to as nanoplastics rather than microplastic (Koelmans et al., 2015).Although microplastics …Microplastics are discharged into the environment through human activities and are persistent in the environment.

Background While the use of plastic materials has generated huge societal benefits, the ‘plastic age’ comes with downsides: One issue of emerging concern is the accumulation of plastics in the aquatic environment. Here, so-called microplastics (MP), fragments smaller than 5 mm, are of special concern because they can be ingested …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. Nov 15, 2021 · Microplastics of <100 μm only accounted for 28% in the lake surface water but were as high as 70% in the sediment, indicating that smaller microplastics may more easily settle in the lake. The main components of the microplastics were identified as being polyvinyl chloride and polyethylene. In smaller lakes, concentrations of microplastics in lake sediments have been shown to reflect processes influencing surface water distributions, such as prevailing wind or proximity to inputs, suggesting that denser polymer types undergo transport through the lake prior to sedimentation (Vaughan et al. 2017).The contamination of aquatic environments by microplastics has been largely documented in the last years, especially in oceans, rivers, and lakes, but their occurrence in remote mountain lakes has been scarcely considered. This work aims to investigate the presence and abundance of microplastics and fibres in a remote, alpine, and uninhabited lake in Switzerland (Sassolo). In this study, the ...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.According to the United States Geological Survey, there are 112,000 particles of microplastics per square mile of Great Lakes water. Inconsistent testing PhD student Kennedy Bucci collecting microplastic samples (Photo courtesy of Kennedy Bucci)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).
