Beyond being mobile and bioaccumulative, PFAS compounds have also been shown to be toxic, though those dangers only became well known in the early 2000s. Reprod Toxicol 27(3–4):342–351, Wang ZY, Cousins IT, Scheringer M et al (2015) Hazard assessment of fluorinated alternatives to long-chain perfluoroalkyl acids (pfaas) and their precursors: status quo, ongoing challenges and possible solutions [J]. Not logged in PFAS stay in the human body for long periods of time. These animal studies have found that PFAS can cause damage to the liver and the immune system. This service is more advanced with JavaScript available, Emerging Chemicals and Human Health But he warned that these two are ‘just the tip of the iceberg’. 2017;14(1):188‐195. Environ Monit Assess 189(3):100, Ahrens L, Felizeter S, Sturm R et al (2009) Polyfluorinated compounds in waste water treatment plant effluents and surface waters along the river elbe, Germany [J]. Humans are exposed to many chemicals in addition to PFCs. Perfluorinated compounds (PFCs) comprise a large group of chemicals that have been produced about 50 years. Environ Sci Technol 45(19):8151–8159, Chen MH, Ha EH, Wen TW et al (2012) Perfluorinated compounds in umbilical cord blood and adverse birth outcomes [J]. However, these studies are not consistent and may not have looked at other factors, such as smoking habits. Scientists have ways to estimate how the exposure and effects in animals compare to what they would be in humans.

Increase the risk of an asthma diagnosis. Environ Res 154:145–151, Hu XDC, Dassuncao C, Zhang XM et al (2018) Can profiles of poly- and perfluoroalkyl substances (pfass) in human serum provide information on major exposure sources? At this time, scientists are still learning about the health effects of exposures to mixtures of different PFAS. @~ (* {d+��}�G�͋љ���ς�}W�L��$�cGD2�Q���Z4 E@�@����� �A(�q`1���D ������`'�u�4�6pt�c�48.��`�R0��)� As new studies become available, our understanding of the health impacts of these chemicals in humans will continue to grow. In other words, if the levels of PFOA and PFOS added together exceed 70 ppt, action should be taken to reduce exposure. If humans, or animals, ingest PFAS (by eating or drinking food or water than contain PFAS), the PFAS are absorbed, and can accumulate in the body. As new studies become available, our understanding of the health impacts of these chemicals in humans will continue to grow.

Therefore, it is necessary to study health effects of various PFCs and their alternatives, and analyze the different environmental behaviors of isomers and homologues of PFCs. Carbon-fluorine bonds are among the strongest in organic chemistry. Humans can be exposed to PFCs by ingesting contaminated drinking water and seafood, inhaling polluted indoor air, and other contaminated media, the way of exposure is wide and undetectable. endobj The Centers for Disease Control and Prevention (CDC) cannot attest to the accuracy of a non-federal website. Occupationally-exposed workers may have increased risk of prostate and bladder cancer. However, not all of these studies involved the same groups of people, the same type of exposure, or the same PFAS. CDC is not responsible for Section 508 compliance (accessibility) on other federal or private website. << Background J Immunotoxicol. To provide people, including the most sensitive populations, with a margin of protection from exposure to two specific PFAS chemicals (PFOA and PFOS) in drinking water, EPA established health advisory levels for both PFOA and PFOS at 70 parts per trillion (ppt). The long-term health effects of multiple, low-level exposures are poorly understood.

There is evidence from human and animal studies that PFAS exposure may reduce antibody responses to vaccines (Grandjean et al., 2017, Looker et al., 2014), and may reduce infectious disease resistance (NTP, 2016). There is very limited scientific information on the health impacts of other PFAS chemicals, such as PFHpA, PFHxS, PFNA and PFBS. the human health effects of perfluorinated compounds (PFCs), including perfluorooctane sulfonate (PFOS) and perfluorooctanoic acid (PFOA), the most . This amount is equal to one drop of ink in a backyard swimming pool. Almost everyone has detectable levels of PFOS, PFOA, and other PFCs in their blood. © 2020 Springer Nature Switzerland AG.
