PFOS, its precursors and PFOA, have been targeted by different phase-out initiatives within the last years . As a consequence, the use of some PFOS derivatives (e.g. perfluorooctane sulfonamidoethanol-based phosphate (SAmPAP) esters) in paper and board FCMs has mainly stopped by 2002 . Human exposure to per- and polyfluoroalkyl substances (PFAS) is a public health concern that ATSDR, the CDC, and NCEH are helping our local, territorial, tribal, state, and federal partners address.

Both are fluorinated organic chemicals, part of a larger family of compounds referred to as perfluoroalkyl substances (PFASs). PFOS and PFOA are man-made chemicals belonging to the group known as Per- and poly-fluoroalkyl substances. PFOS, PFOA and related chemicals (Per- and poly-fluoroalkyl substances) have been used, and remain in the environment around several sites in NSW. Se hela listan på environmentalpollutioncenters.org Se hela listan på epa.gov By 2012, PFOS and PFOA were added to the Prohibition of Certain Toxic Substances Regulations. However, since these chemicals do not easily break down, their long-lasting effects are still a concern for homes, the environment and water supplies in North America today.

These chemicals have been produced worldwide since the 1940s. Out of all the substances in the PFAS family, PFOA and PFOS have been studied and produced the most. These chemicals are both persistent, meaning that they are highly resistant to breaking down.

However, the EPA has established health advisories for PFOA and PFOS in drinking water, based largely on the health effects of PFOA and PFOS seen in studies of lab animals (rats and mice). The health advisory level for both of these chemicals (alone or combined) is set at 70 parts per trillion over the course of a person’s lifetime.

Even if the use of these chemicals is restricted in the US, they are still used in other countries, so there is an elevated risk of contamination if the products were produced abroad. PFOS and PFOA have been extensively produced and studied in the United States. These manmade substances have been synthesized for water and lipid resistance. They have been used extensively in consumer products such as carpets, clothing, fabrics for furniture, paper packaging for food, and other materials (e.g., cookware) designed to be A recent halflife analysis was conducted on 9 retired 3M chemical workers. PFOS samples were collected over 4 time periods spanning 180 days, measured in triplicate with all time points from each subject analyzed in the same analytical run. The mean half-life for PFOS was 8.67 years (range 2.29 - 21.3 years, SD = 6.12). However, officials have not regulated any new contaminant in two decades, meaning that the regulation of PFOA is (likely) many years away.
