Overuse of the chemical triclosan in consumer products — particularly antimicrobial soap and the like — may be increasing the risk of bone density loss, especially in women. Fulton Schools Professor Rolf Halden, director of the Biodesign Center for Environmental Health Engineering at ASU, comments on a new study published in the Journal of Clinical Endocrinology & Metabolism that offers more findings pointing to the potential for triclosan to present a health threat. Halden recommends people limit their exposure to the risk by not using products containing the chemical.
