Every one of us, even unborn fetuses, are continually exposed to microplastics that have become such ubiquitous global environmental pollutants that they now contaminate the everyday air, food, and water we take in.
Huge gaps exist in scientific knowledge, but California is about to set the world's first health guidelines for microplastics in drinking water. Yet no one agrees how to test water for the tiny bits of plastic, or how dangerous they are.
Emerging research on microplastics suggests they can leak harmful chemicals into the environment. On the East Coast, one researcher is working to understand the impact of these tiny particles — and reckoning with science's colonial legacy at the same time.
The company scraps planned Pennsylvania investments and will instead shut down three polluting batteries in 2023. The announcement comes a week after a study shows lower lung function in people living near its Pittsburgh-region facility.
