Per- and polyfluoroalkyl substances (PFAS) are a group of man-made chemicals that includes PFOA, PFOS, GenX, and many other chemicals. 3As a result most people have been exposed to PFOS and PFOA, and the two compounds have become a serious concern for wildlife, the environment and human health. PFOA can remain in the body for long periods of time. PFOA can remain in the body for long periods of time. Biomonitoring studies on levels of PFOA provide physicians and public health officials with reference values so that they can determine whether people have been exposed to higher levels of PFOA than are found in the general population. Workers in the perfluorochemical industry can be exposed to greater amounts of PFOA than people in the general population.The human health effects from exposure to low environmental levels of PFOA are unknown. These studies indicate that exposure to PFOA and PFOS over certain levels may result in adverse health effects, including developmental effects to fetuses during pregnancy or to breastfed infants (e.g., low birth weight, accelerated puberty, skeletal variations), cancer (e.g., testicular, kidney), liver effects (e.g., tissue damage), immune effects (e.g., antibody production and immunity), thyroid effects and other … PFOA persists in the environment and does not break down.
In laboratory animals given large amounts, PFOA can affect growth and development, reproduction, and injure the liver. PFOA may increase the risk of testicular cancer. Both chemicals are very persistent in the environment and in the human body meaning they dont break down and they can accumulate over time…
It makes products water- or oil-resistant.PFOA may increase the risk of testicular cancer.PFOA exposure can cause cough, sore throat, redness and pain in the eyes or skin, abdominal pain, nausea, vomiting, and diarrhea.PFOA may adversely affect the cardiovascular, endocrine, digestive, urinary, and reproductive systems. PFOA exposure can cause cough, sore throat, redness and pain in the eyes or skin, abdominal pain, nausea, vomiting, and diarrhea. PFAS have been manufactured and used in a variety of industries around the globe, including in the United States since the 1940s. Its persistence, presence in the environment and bioaccumulation potential indicate cause for concern. Other studies have also shown that the chemical is potentially associated to kidney cancer and thyroid cancer, although the increases in risk have been small. In laboratory animals given large amounts, PFOA can affect growth and development, reproduction, and injure the liver. Biomonitoring data can also help scientists plan and conduct research on exposure and health effects.People are most likely exposed to PFOA by drinking contaminated water sources, and possibly by using products that contain PFOA. More research is needed to assess the human health effects of exposure to PFOA. Perfluorochemicals (PFCs) are a group of chemicals used to make fluoropolymer coatings and products that resist heat, oil, stains, grease, and water. The long-term effects of PFOA and similar chemicals are largely unknown, but there has been enough concern to prompt an attempt to phase out industrial emissions of them. PFOA was used particularly for manufacturing polytetrafluoroethylene, but since 2002, manufacturers have used a new process not requiring this chemical. PFOA has been identified in bodies of water and in a variety of land and water animals.Finding measurable amounts of PFOA in serum does not imply that the levels of PFOA cause an adverse health effect.
It has been detected in a number of species of wildlife, including marine mammals. PFOS is persistent in the environment and has been shown to bioconcentrate in fish.
