Abstract

Gas chromatograph- mass spectrometry method is adopted to carry out quantitative analysis on formamide content in 100 batches of Yoga mat products, and carry out environmental chamber release and perspiration migration migration simulation test. The inhalation exposure model and skin contact exposure model are established to analyze risks in accordance with EU’s calculation model for chemical substance exposure quantity and in combination with use characteristics of Yoga mat. After comparing hazardous degree of formamide to different people in different scenarios, the research finds that the daily average exposure quantity to children in the same scenario is higher than that to adults; for the same group of people, the daily average exposure quantity in Yoga Clubs is higher than at home. Thus, it is necessary to avoid taking children to venues with intensive yoga mats such as Yoga Clubs.
