Antibacterial Agent Used in Common Soaps Found in Increasing Amounts in Freshwater Lakes (Jan. 22, 201)
A new University of Minnesota study determined that the common antibacterial agent, called triclosan, used in soaps and many other products is found in increasing amounts in several Minnesota freshwater lakes ... the researchers found an increasing amount of other chemical compounds, called chlorinated triclosan derivatives, that form when triclosan is exposed to chlorine during the wastewater disinfection process. When exposed to sunlight, triclosan and its chlorinated derivatives form dioxins that have potential toxic effects in the environment. These dioxins were also found in the lakes.
