Microplastics Are Chemically Alive and Probably Up to No Good
New research points to a "possibly overlooked mechanism" for how microplastics can harm people's health.
An anonymous reader quotes a report from Scientific American: Microplastics are a source of extreme concern for health: the presence of these tiny pieces of plastic has been linked to heart attacks, stroke, dementia and brain tumors. But what drives these associations is unclear. Now a study published in Nature offers a tantalizing clue: microplastics interact with water, generating highly reactive molecules. When microplastics come into contact with water, the water near their surface can become chemically active, generating highly reactive species that can modify nearby substances, including biologically important molecules.
