Triclosan Ban

Ecology and Environment

MSI PI Bill Arnold (Civil, Environmental, and Geo- Engineering) has spent years studying the effects of triclosan, an anti-bacterial chemical used in household products. He showed that the chemical, which is a hormone disruptor, was building up in Minnesota lakes. His research contributed to a decision by state lawmakers to ban the use of the substance in Minnesota; that ban takes effect in 2017. Minnesota was the first state to take this step, and other government agencies followed suit. 

A story appears on the WCCO-TV website: Minnesota Becomes 1st State to Ban Potentially Harmful Germ Killer.
