As much as 70% of all plastic in Norwegian salmon rivers comes from round ball plastic in agriculture, according to a new study from the Norwegian Research Center (Norce).
The researchers from Norce studied the plastic in 43 Norwegian rivers in Western Norway, and the numbers are clear.
“We have mapped the quantities and sources of macroplastics, i.e., visible, large pieces of plastic, in 43 rivers corresponding to 200 kilometers with river stretches along the whole of Western Norway from Rogaland in the south to Møre and Romsdal in the north.
“This is the first systematic survey of plastic in rivers in Norway,” Gaute Velle, a researcher in Norce, said in a press release.
In 21 of the rivers, the researchers registered a total of approximately 1,100 meters of foil from round bales divided into around 1,500 pieces.
The researchers found three times as much round ball plastic than all the other plastic categories combined.
