2. 1. Sources, transport and fate of perfluoroalkyl acids in the atmosphere

   Author : Jana Johansson; Ian Cousins; Tom Harner; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Perfluorinated alkyl acids; PFOS; PFOA; Isomers; Sources; Atmospheric transport; Sea spray; Gas-particle partitioning; Volatilisation; Applied Environmental Science; tillämpad miljövetenskap;

   Abstract : Perfluoroalkyl acids (PFAAs) are man-made chemicals which have been observed in the global environment, even in locations far away from where they are emitted. These persistent substances are taken up in humans and biota and may have toxic effects. READ MORE

4. 2. From emission sources to human tissues: modelling the exposure to per- and polyfluoroalkyl substances

   Author : Melissa Ines Gomis; Ian Cousins; Robin Vestergren; Hermann Fromme; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; PFAAs; PFOA; PFOS; fluorinated alternatives; human exposure; pharmacokinetic modelling; hazard assessment; Applied Environmental Science; tillämpad miljövetenskap;

   Abstract : Produced since the 1950’s, per- and polyfluoroalkyl (PFASs) substances are persistent, bioaccumulative and toxic compounds that are ubiquitous in the environment. Being proteinophilic with a tendency to partition to protein-rich tissues, PFASs have been found in human serum worldwide and in wildlife with a predominance of long-chain perfluoroalkyl carboxilic acids (C7-C14 PFCAs) and perfluoroalkyl sulfonic acids (C6-C9 PFSAs).

5. 3. Comparative avian developmental toxicity of PFAAs

   Author : Marcus Nordén; Magnus Engwall; Krister Halldin; Anders Bignert; Örebro universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; chicken; herring gull; cormorant; PFAA; PFOS; PFOA; toxicity; levels; Biology; Biologi;

   Abstract : Perfluoroalkyl acids (PFAAs) are persistent organic pollutants that can commonly be found in environmental matrixes and wildlife from all over the globe. The PFAAs have been used in applications such as water and dirt repelling treatments for textiles, oil-resistant paper coatings and fire-fighting foams. READ MORE

6. 4. Mass balance of perfluoroalkyl acids in the Baltic Sea

   Author : Marko Filipovic; Urs Berger; Michael McLachlan; Bert Ove Lund; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; PFOA; PFOS; mass balance; Baltic Sea; PFOA; PFOS; massbalans; Östersjön; miljökemi; Environmental Chemistry;

   Abstract : Perfluoroalkyl acids (PFAAs) are man-made chemicals. Their unique properties make them beneficial for a wide range of industrial and consumer applications, such as constituents in fire fighting foams, hydraulic oils and food packaging materials. READ MORE

7. 5. Brominated flame retardants and perfluoroalkyl acids in Swedish indoor microenvironments : Implications for human exposure

   Author : Justina Björklund; Cynthia de Wit; Thomas Webster; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; PBDEs; HBCD; PFOS; PFOA; indoor air; indoor dust; breast milk; human exposure; emission; Applied Environmental Science; tillämpad miljövetenskap;

   Abstract : Humans are exposed to persistent organic pollutants (POPs) such as brominated flame retardants (BFRs, specifically polybrominated diphenyl ethers (PBDEs) and hexabromocyclododecane (HBCD)) and perfluoroalkyl acids (PFAAs, specifically perfluoroalkane sulfonate (PFOS) and perfluorooctanoic acid (PFOA)). They are used in consumer products found in cars, offices, homes and day care centers. READ MORE
