Leaks from cars and trucks are a major source of chemical pollution

Substances harmful to organisms' health, including metals, pesticides, persistent organic pollutants, chlorination byproducts, and pharmaceuticals, find their way into estuarine waters through pathways like direct pesticide or herbicide application, storage leaks, accidental releases, or atmospheric deposition. Some waterborne chemical contaminants adhere to suspended silts and sediments and tend to bioaccumulate in tissues of aquatic life, from algae to fish, ultimately threatening the health of humans.

Common Sources: old paint, antifreeze & oil leaks, exessive use of pesticides, polystyrene plastic
