ANN ARBOR - Recent laboratory testing by the Ecology Center, a nonprofit in downtown Ann Arbor, found that some yoga mats claiming to be eco-friendly are made of materials that are hazardous to the environment and to human health. The center's Healthy Stuff Lab tested 11 yoga mats of different brands that were purchased by editorial and customer review website Consumers Advocate. The yoga mats made of PVC contained the plasticizer DOTP, a substitute for phthalates that is likely safer but needs more research. "I had not heard of PER before," Gillian Miller, an Ecology Center senior staff scientist, said in a statement. To test the yoga mats, Healthy Stuff Lab scientists used Fourier Transform Infrared Spectroscopy and high-definition X-ray fluorescence (XRF).
