Exposure to environmental toxicants is associated with numerous disease outcomes, many of which involve underlying immune and inflammatory dysfunction. The U.S. government declared Bisphenol A (BPA) a hazardous substance in October 2008 and has since placed it on its list of toxic substances. Triclosan (2,4,4’ –trichloro-2’-hydroxydiphenyl ether) is a chlorinated aromatic anti-microbial agent under review by the U.S. Environmental Protection Agency (EPA) using the new National Health and Nutrition Examination Survey (NHANES) 2003-2006 data.
Using data from the 2003-2006 NHANES, a study in the journal Environmental Health Perspectives compared urinary BPA and triclosan with diagnoses of allergies or hayfever in U.S. adults and children age ≥ 6 years.
Triclosan, but not BPA, showed a positive association with allergy/hayfever diagnosis. In the under-18 age group, higher levels of triclosan were associated with greater odds of having been diagnosed with allergies or hayfever (p<0.01).
Although additional studies should be done to investigate these interesting findings, shall we further restrict the use of BPA ?
