Studies about plastic pollution in the oceans are fairly common, ranging from the impact pollution has on marine life (like whales and sea turtles ) to efforts to cleanup the mess. A new study from Lund University is one of only a few that focuses on the impact nanosized plastic particles have on marine life.
“Plastic particles of such a small size are difficult to study,” lead author, Karin Mattsson, explained in a news release.
Mattsson and the team studied the impact of nanoplastics on Daphnia, a type of zooplankton that forms the basis of the food chain for many marine animals. They found that fish that ate Daphnia containing nanoplastics experienced changes in their predatory behavior and reduced appetite.
“Although in our study we used much larger amounts of nanoplastic than those present in oceans today, we suspect that plastic particles may be accumulated inside the fish. This means that even low doses could ultimately have a negative effect,” Mattsson said.
