Biomonitoring studies on levels of PFAS provide physicians and public health officials with reference values. įinding a measurable amount of PFAS in serum does not imply that the levels of PFAS cause an adverse health effect. The data tables showing results since 1999 are available here. This indicates widespread exposure to these PFAS in the U.S.

By measuring PFAS in serum, scientists can estimate the amount of PFAS in people’s bodies.ĬDC scientists found four PFAS (PFOS, PFOA, PFHxS or perfluorohexane sulfonic acid, and PFNA or perfluorononanoic acid) in the serum of nearly all of the people tested. Blood serum is obtained from participants, aged 12 years and older, who have taken part in the National Health and Nutrition Examination Survey (NHANES) (Fourth National Report on Human Exposure to Environmental Chemicals, Updated Tables). Since 1999, CDC scientists have measured at least 12 PFAS in blood serum (the clear portion of blood). More research is necessary to assess the human health effects of exposure to PFAS. Descriptions of these studies are available at. Epidemiologic studies on PFAS exposure evaluated several health effects. Studies of laboratory animals given large amounts of PFAS indicate that some PFAS may affect growth and development. In addition, these animal studies indicate PFAS may affect reproduction, thyroid function, the immune system, and injure the liver. Human health effects from exposure to low environmental levels of PFAS are uncertain.

Exposure may happen by using products that contain PFAS. PFAS persist in the environment and exposure in people can occur by consuming PFAS-contaminated water or food.

PFAS are found in rivers and lakes and in many types of animals on land and in the water.
