North Carolina State University discovered that the fish that live near the Coal-Fired Power Plant have lower levels of mercury than fish that live further away. The researchers found their findings very surprising because coal-fired power plants typically the leading source to emitting mercury in the air. Now the researchers tested fish that were in different lakes, fish that lived 10 kilometers away, and fish that live 30 kilometers away, as well. The species that choose to test were the largemouth bass and bluegill, because they were commonly caught and eaten by fisherman. Plus these fish come from different places on the food chain. The largemouth bass is at the top of it’s food chain and does really have any predators of it’s own, and feed on smaller fish. Largemouth bass show higher levels of mercury. The bluegill is a really small fish and feeds on invertebrates and show lower levels of mercury. They found that mercury levels went up in both species.
