A new measurement technique developed by the research team, led by URI Graduate School what method should you use if you are interested in determining cause and effect Oceanography scientists, detected PFAS chemicals in the air of kindergarten classrooms, thw 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. 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 what are examples of i statements infertility to immune system problems. By affixing polyethylene sheet samplers to ceilings, the scientists measured volatile PFAS chemicals in the air of nine carpeted kindergarten classrooms, one home, and the storage room of an cemical clothing store in California; as well as two laboratories, five offices, one classroom, one storage room, and one elevator at the University of Rhode Island; and two carpet stores, also in Rhode Island.

PFAS were detected brreathe the air at nearly every location. Several kindergarten classrooms and rooms at the university had higher indoor air concentrations of PFAS than the storage room of the outdoor clothing store, which was full of jackets what is the chemical makeup of the air we breathe gear treated with PFAS. The highest concentrations were found in the two carpet stores. We believe that slowly smaller retailers will do so as well.

While families, schools, and workplaces can reduce indoor air levels of PFAS by replacing carpets, there are still many other products that can emit volatile PFAS into indoor air, including clothing, shoes, building products, and furnishings. Skip to content. Connect Apply Tour Give.
