Here is a useful page.

Tuna is in the high/highest mercury group.

Lake fish are at risk of being more polluted.

"Mercury emissions from coal-fired power plants and other industrial sources are making the fish in our lakes, rivers, and streams unsafe to eat. Coal-fired power plants are by far the nation’s largest unregulated source of mercury emissions, contributing 41 percent of all U.S. mercury emissions. The mercury deposits in soil and surface waters, where bacteria convert it to a highly toxic form of mercury that bioaccumulates in fish, including popular sport and commercial fish. This report analyzes new data from the U.S. Environmental Protection Agency (EPA) to determine the extent to which fish in the nation’s lakes are contaminated with mercury."

"Mercury pollution is pervasive in the nation’s lakes. Every fish sample EPA tested was contaminated with mercury, and the majority of the fish samples were contaminated with mercury at levels that could pose a public health risk. The results underscore the need to reduce mercury emissions to the greatest extent possible, as fast as possible."

"The most common source of mercury exposure for Americans is tuna fish. Tuna does not contain the highest concentration of mercury of any fish, but since Americans eat much more tuna than they do other mercury-laden fish, such as swordfish or shark, it poses a greater health threat. (For more, see our guides to mercury levels in fish and to eating tuna safely.)"

"Subsistence and sports fishermen who eat their catch can be at a particularly high risk of mercury poisoning if they fish regularly in contaminated waters. Across the United States, mercury pollution is known to have contaminated 12 million acres of lakes, estuaries, and wetlands (30 percent of the total), and 473,000 miles of streams, rivers, and coasts. And many waterways have not even been tested. In 2003, 44 states issued fish consumption advisories, warning citizens to limit how often they eat certain types of fish caught in the state's waters because they are contaminated with mercury."
