New paper in Food webs

New publication about microplastics in Food webs

Macroplastics is a huge problem globally – in 30 years we will have more plastics than fish in the ocean if the present pollution continues. Macroplastics are over the years rubbed into microplastics, tiny filaments that may get eaten by fish, shrimps and mussels. Did you know that the filaments eventually may end up on your dinner plate?

In a new publication by Maiju Lehtiniemi et al., with co-authors from SYKE, University of Eastern Finland and Novia, we have studied if microplastics (from the ketchup bottle) are fed upon by planktivores, and yes, they are, but luckily only in small amounts.
