So you would never flush dioxins into your water supply, right? If you use antibacterial soaps and other antibacterial products, you could be doing the equivalent of just that.
In 2003 and 2009, University of Minnesota civil engineering professor William Arnold and his colleague Kristopher McNeill published their discovery that the antibacterial agent triclosan, when exposed to sunlight, generates a specific group of four dioxins. Now, in a new study, a team of scientists from the University of Minnesota’s Institute of Technology, Pace Analytical (Minneapolis), the Science Museum of Minnesota and Virginia Tech, have documented how triclosan is transformed into dioxins that are accumulating in the environment. This research, just published in the journal Environmental Science and Technology, concludes dioxins originating from triclosan (found in many hand soaps, deodorants and dishwashing liquids) account for a huge increase in total dioxins now polluting Mississippi River sediments.
