A U.S. Environmental Protection Agency scientist says toxic dioxin found in the Saginaw River could be the most concentrated ever discovered in the nation's rivers and lakes.
Milton Clark says no other recorded finding comes close to the 1.6 million parts of dioxin per trillion reported last week. Clark is involved in cleanup efforts downstream from Dow Chemical Co. facilities in Midland.
In response, Michigan Department of Community Health officials have issued a fish consumption advisory for the Tittabawassee River, the Saginaw River and a portion of Saginaw Bay. The advisory warns against eating carp, catfish and white bass. It also alerts women of childbearing age and children against eating certain types of fish.
Some dioxins have been linked to cancer and other health problems.
