Plastic nanoparticles affect behavior and fat metabolism in fish
(Nanowerk News) Nanoparticles have many useful applications, but also raise some potential health and ecological concerns. Now, new research shows that plastic nanoparticles are transported through the aquatic food chain and affect fish metabolism and behavior.
Exposing fish to nanoparticles slowed their feeding behavior, and also affected metabolic parameters including weight loss and cholesterol levels and distribution. The authors, led by Tommy Cedervall, Lars-Anders Hansson and Sara Linse of Lund University in Sweden, suggest that their results could be useful for developing assays to test for nanoparticles and investigate potential biological risks associated with them.
