Plastic nanoparticles affect behavior and fat metabolism in fish

Feb 22, 2012

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 and behavior.

The full report is published Feb. 22 in the open access journal .

Exposing fish to nanoparticles slowed their feeding behavior, and also affected metabolic parameters including weight loss and 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.
