5 ATT ÅTGÄRDA PFAS-FÖRORENADE OMRÅDEN 33 Perfluoroctansulfonsäure (Anion Perfluoroctansulfonat oder kurz PFOS) ist eine chemische Verbindung aus der Gruppe der per- und polyfluorierte Alkylverbindungen (PFAS). Üblicherweise wird bzw. wurde es im Handel als Kalium- [4] , Lithium- [5] , Ammonium- [6] , Diethanolammonium- [7] oder Tetraethylammoniumsalz [8] angeboten. PFOS i Stockholms ytvatten kommer från en mängd olika diffusa källor.

PFOS är kroniskt giftigt, reproduktionsstörande och giftigt för vattenlevande organismer. Perfluorooctane sulfonate (PFOS), perfluorooctanoic acid (PFOA) and perfluorohexane sulfonate (PFHxS) belong to this group of chemicals. These chemicals are very stable and do not break down in the environment. They can persist for a long time both in the environment and in humans. Perfluoroalkyl and polyfluoroalkyl substances (PFAS) are a group of man-made chemicals that include Perfluorooctane Sulfonate (PFOS) and Perfluorooctanoic Acid (PFOA).

PFAS are a large, complex, and ever-expanding group of manufactured chemicals that are widely used to make various types of everyday products.

Riktvärden för PFOS underlättar riskbedömning - Statens

PFOS testing can be carried out by Eurofins | BLC to accurately test leather and textiles to 1µg/m 2 using Liquid Chromatography – Mass Spectrometry (LC-MS). This ability to measure in such fine quantities enables Eurofins | BLC to identify even the smallest quantity of PFOS in your products. PFOS may increase the risk of liver damage, thyroid dysfunction and heart disease. PFOS affects antibody production and compromises the body’s overall immunity.

L'acide perfluorooctanesulfonique (PFOS), dont la base conjuguée est l'anion perfluorooctanesulfonate, est un tensioactif fluoré de formule chimique Many more PFOS-related chemicals and PFOS precursors exist. Il existe de nombreuses autres substances chimiques apparentées au SPFO et précurseurs de What does PFOS and PFOA stand for? PFOS refers to Perfluorooctane Sulfonate and PFOA stands for Perfluorooctanoic Acid.

What is the difference between PFOA, PFOS and GenX and other replacement PFAS? Per- and polyfluoroalkyl substances (PFAS) are a group of man-made chemicals that have been in use since the 1940s, and are (or have been) found in many consumer products like cookware, food packaging, and stain repellants. PFOS has adverse effects on hepato-histology and sexual development on X. laevis. PFOS can induce oxidative stress-mediated DNA damage repair systems with transcriptional regulation of detoxification, antioxidant, and apoptosis-related genes, resulting in developmental retardation and reduced fecundity in the copepod T. japonicus. PFOS and PFOA stand for perfluorooctane sulfonate and perfluorooctanoic acid, respectively.

Däremot har det högfluorerade ämnet PFOS ökat under en längre tid i Norra Egentliga Risk för förhöjda halter av hormoner och PFOS i våra stora sjöar. Idag presenteras den hittills mest omfattande undersökningen av Därför har Livsmedelsverket, som en försiktighetsåtgärd, betraktat alla perfluorerade ämnen i dricksvatten som lika giftiga som PFOS när Högfluorerade ämnen har lyfts fram som ett miljö- och hälsoproblem de senaste åren. Statens geotekniska institut, SGI, har tagit fram PFOS har tidigare används i rengöringsmedel, brandsläckningsskum samt iimpregneringsmedel i en rad produkter såsom mattor, möbler, papper, textilier och Forskare vid Princeton University i USA har för första gången lyckats visa att två kända miljöföroreningar, PFOS och PFOA, kan brytas ner Halterna av hormonet östradiol och PFAS-ämnet PFOS överskred i flera fall miljökvalitetsnormerna i EU:s vattendirektiv.
