Microplastics can pick up pollution in their travels and pose an even greater threat to human health, according to a new study.
In the ocean, for example, toxic compounds can hitch a ride on plastic and make the material 10 times more toxic than it would normally be, according to the research published earlier this year in Chemosphere.
Although the dangers of both microplastics and harmful compounds have been studied individually, few researchers have look at their combined effect. This study is also unique in that the researchers tested these polluted plastic particles on human cells—most previous research has focused on the impacts on marine life.
