From the cars we drive to the pre-packaged food we eat, the use of plastics in consumer’s lives only continues to grow. It’s showing up on our beaches and in our parks, but what about the plastics we can’t see or can barely touch? According to a recent article from the New York Times, scientists say it could be years before we have a full understanding of how microplastics and nanoplastics are affecting human health. These tiny particles are turning up everywhere — from the deepest parts of the ocean to the food on our plates, and even inside our bodies.

On this episode of Saint Mary’s Currents, join Peter Pfaff, Ph.D., assistant professor of biology at Saint Mary’s as we ask: what are micro and nanoplastics, and where are they coming from? And what are the real-world consequences of their widespread presence on the environment and our health?
