Microwaving plastic food containers can release billions of small toxic plastic particles, according to a study. The researchers found that microwaving plastic baby food containers released over two billion nanoplastics and four million microplastics for every square centimeter of container in some cases. The study, published recently in the journal Environmental Science & Technology, also found that three-quarters of cultured embryonic kidney cells had died after two days of being introduced to those same particles. "It is really important to know how many micro- and nanoplastics we are taking in," said Kazi Albab Hussain, the study's lead author and a doctoral student at the University of NebraskaLincoln, US. "Many studies, including ours, are demonstrating that the toxicity of micro- and nanoplastics is highly linked to the level of exposure, Hussain added. The team conducted experiments with two baby food containers made from polypropylene and a reusable pouch made of ...
