Nanoplastics: Small particles, big problems

Nanoplastics are attracting growing concern thanks to recent technological advances that have made researchers more able to detect and analyze them. It’s become common to read that microplastics—little bits of plastic, smaller than a pencil eraser—are turning up everywhere and in everything, including the ocean, farmland, food and human bodies. Now a new term is gaining attention: nanoplastics. These particles are even tinier than microplastics—so small that they’re invisible to the...
