The results show that indoor air is an underestimated and potentially important PFAS Sources of exposure, especially for children.

Senior author of the study, Rhode Island University Oceanography Professor Rainer Lohmann said: “Food and water are known to be the main sources of PFAS exposure. Our research shows that indoor air, including dust, is another source of exposure to potentially harmful permanent chemicals. In fact. For children living in homes or schools with old PFAS-treated carpets, inhalation may be more important than dust as a way of exposure to volatile PFAS. These PFAS will eventually be biotransformed into more durable and harmful PFAS. ”

After thorough research, PFAS has been linked to a series of serious health hazards, such as cancer, infertility and immune system problems. All PFAS are either extremely persistent in the environment, or they will be decomposed into stronger PFAS.

By attaching the polyethylene sheet sampler to the ceiling, the scientists measured 9 carpeted kindergarten classrooms, 1 family and 1 outdoor clothing store storage room in California; and Rhode Island The university’s 2 laboratories, 5 offices, 1 classroom, 1 storage room, and 1 elevator; and 2 carpet shops (also in Rhode Island) have volatile PFAS chemicals in the air. The results show that almost PFAS was detected in the air everywhere.

The concentration of PFAS in the classrooms and rooms of several affiliated kindergartens of the university is even higher than that in the storage rooms of outdoor clothing stores (where there are piles of PFAS-treated jackets and equipment). The highest concentrations were found in two carpet shops. The lead author of the paper, Maya Morales-McDevitt, said: “PFAS was previously used as an antifouling and waterproofing agent for most carpets. Fortunately, major retailers including The Home Depot and Lowe’s now only sell PFAS-free products. Carpets. We believe that slowly small retailers will do the same.”

Although homes, schools, and workplaces can reduce the PFAS content in indoor air by replacing carpets, there are still many other products that can emit volatile PFAS into indoor air, including clothes, shoes, and buildings. Products and furniture.

“As long as they continue to be used in products, we will all eat, drink and breathe PFAS,” said co-author Tom Bruton, a senior scientist at the Green Science Policy Institute. “We need to stop all unnecessary PFAS use as soon as possible.”
