Billions of nanoplastics released when microwaving baby food containers

The fastest way to heat food and drink might also rank as the fastest route to ingesting massive quantities of minuscule plastic particles, says new research from the University of Nebraska-Lincoln. Experiments have shown that microwaving plastic baby food containers available on the shelves of U.S. stores can release huge numbers of plastic particles - in some cases, more than 2 billion nanoplastics and 4 million microplastics for every square centimeter of container.
