Water South Carolina Bridges Charleston Historic

Groundbreaking research by biology professor John Weinstein, Ph.D., shows that seven tons of microscopic plastic particles can be found floating in Charleston Harbor, and more than 90 percent of the particles are tiny pieces of tire.

These tire particles are a kind of microplastic, which is something people have become increasingly aware of as a form of pollution. These particles are consumed by wildlife, like shrimp, and work their way up the food chain.
