Plastic debris on the shores of two antartic lakes
In recent years, plastic pollution has become a major global concern. Plastic debris has been found in all environmental compartments, even in remote areas such as Antarctica. Within Antarctica, their presence has already been reported in marine waters and sediments, sea ice, local organisms, freshw...

In recent years, plastic pollution has become a major global concern. Plastic debris has been found in all environmental compartments, even in remote areas such as Antarctica. Within Antarctica, their presence has already been reported in marine waters and sediments, sea ice, local organisms, freshwater, soil, glaciers, beaches, and recently, it's atmosphere. However, there is little evidence of the occurrence of plastic debris in Antarctic freshwater. Here, we investigated the presence of plastic debris on the shores of two Antarctic lakes (Lake Profound/Uruguay and Lake Deep/Ionosférico) located in the northeast of Fildes Peninsula (King George Island, Antarctica). Plastic debris was collected on the shores of both lakes. Afterwards, it was characterized, identified and quantified. The results showed a predominance of mesoplastics, with expanded polystyrene (EPS) (69.52%) and polyurethane (PUR) (14.37%) being the predominant polymer types, with other polymer types such as polyethylene (PE) and polypropylene (PP) being minoritary (3.49% and 2.33%, respectively).
