MINNEAPOLIS (AP) – New research shows a compound found in popular anti-bacterial soaps, cosmetics and toothpastes is creating toxins in Minnesota lakes and rivers.

University of Minnesota scientists studied the sediment in eight lakes of various sizes and found amounts of the antibiotic triclosan and its derivatives have been steadily increasing.

The research was published Tuesday in the journal Environmental Science and Technology. The study’s lead author, William Arnold, says it’s important for people to know that the products they use in their homes every day can have an impact on the environment. Arnold says the research should help chemical manufacturers understand the potential long-term effects of triclosan.

The U.S. Environmental Protection Agency and the Food and Drug Administration are studying the effects of triclosan on animal and environmental health.
