The air we breathe in our homes, school and workplaces can be polluted with harmful PFAS chemicals, according to a study published today in Environmental Science & Technology Letters. A new measurement technique developed by the research team, led by URI Graduate School of Oceanography scientists, detected PFAS chemicals in the air of kindergarten classrooms, university offices and laboratories, and a home—some with levels as high as those measured at an outdoor clothing company and carpet stores selling PFAS-treated products. The results suggest indoor air is an underestimated and potentially important source of exposure to PFAS, particularly for children.
“Food and water are known to be major sources of PFAS exposure,” said Rainer Lohmann, senior author of the study and professor of oceanography at the University of Rhode Island. “Our study shows that indoor air, including dust, is another source of exposure to potentially harmful forever chemicals. In fact, for children in homes or schools with old PFAS-treated carpets, inhalation may be even more important than dust as an exposure pathway to volatile PFAS that eventually could biotransform to more persistent and harmful PFAS.”
Well-studied PFAS have been associated with a wide range of serious health harms, from cancer to infertility to immune system problems. All PFAS are either extremely persistent in the environment or break down into extremely persistent PFAS.
