Triclosan becomes Dioxin: U of M Study
A new University of Minnesota study found that certain types of dioxins derived from Triclosan are present in the sediments of the Mississippi River as it flows through Southeastern Minnesota.
This is additional documentation of a known phenomena. In March of 2007 Dr. Weiss blogged about the problem of Triclosan surviving the wastewater treatment process and then combining with chlorine and sunlight to become dioxin.
The U of M team’s study of core sediment samples from Lake Pepin, revealed the four dioxins derived from triclosan. “These four dioxins only come from Triclosan. They didn’t exist in Lake Pepin before Triclosan was introduced,” said U of M civil engineering professor William Arnold who led earlier discoveries of the dioxins and also supervised the current research.
The levels of the four dioxins derived from Triclosan have risen by 200 to 300 percent while the levels from most dioxins have dropped by 73 to 90 percent over the last 30 years as public awareness spawned efforts to reduce them.
This proves that public awareness and action can help to solve this problem. Get the word out!
