Distinct polymer-dependent sorption of persistent pollutants associated with Atlantic salmon farming to microplastics
Interactions of microplastics and persistent organic pollutants (POPs) associated with Atlantic salmon farming were studied to assess the potential role of microplastics in relation to the environmental impact of aquaculture. HDPE, PP, PET and PVC microplastics placed for 3 months near fish farms so...
