1. 1. Indoor emissions and fate of flame retardants : A modelling approach

   Författare :Ioannis Liagkouridis; Ian Cousins; Anna Palm Cousins; Thomas McKone; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; flame retardants; BFRs; OPFRs; indoor environment; emissions; fate; modelling; Applied Environmental Science; tillämpad miljövetenskap;

   Sammanfattning : A significant number of consumer goods and building materials act as emission sources of flame retardants (FRs) in the indoor environment. As a result, FRs have become ubiquitous indoors raising concerns about human exposure and possible health implications. LÄS MER

3. 2. Fate of Pharmaceuticals and Their Transformation Products in Rivers : An integration of target analysis and screening methods to study attenuation processes

   Författare :Zhe Li; Anna Sobek; Michael McLachlan; Michael Radke; Kathrin Fenner; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; pharmaceuticals; transformation products; fate; river; suspect screening; non-target screening; Applied Environmental Science; tillämpad miljövetenskap;

   Sammanfattning : Pharmaceuticals are environmental contaminants causing steadily increasing concern due to their high usage, ubiquitous distribution in the aquatic environment, and potential to exert adverse effects on the ecosystems. After being discharged from wastewater treatment plants (WWTPs), pharmaceuticals can undergo transformation processes in surface waters, of which microbial degradation in river sediments is considered highly significant.

4. 3. Targeted and untargeted analysis of organic contaminants from on-site sewage treatment facilities : Removal, fate and environmental impact

   Författare :Kristin Blum; Peter Haglund; Patrik Andersson; Pim Leonards; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; decentralized sewage treatment; wastewater; surface water; environmental fate; bioavailability; removal efficiency; mass fluxes; biochar; environment; GC×GC-MS; LC-IM-MS; mass spectrometry; contaminants; pollutants; prioritization; non-target analysis; screening; analytisk kemi; Analytical Chemistry;

   Sammanfattning : On-site sewage treatment facilities (OSSFs) are widely used all over the world to treat wastewater when large-scale sewage treatment plants (STPs) are not economically feasible. Although there is great awareness that the release of untreated wastewater into the environment can lead to water-related diseases and eutrophication, little is known about organic contaminants and their removal by OSSFs, environmental load and fate.

5. 4. Environmental occurrence and fate of semifluorinated n-alkanes and perfluorinated alkyl acids present in ski waxes

   Författare :Merle M. Plassmann; Urs Berger; Michael McLachlan; Crispin Halsall; Stockholms universitet; []
   Nyckelord :Semifluorinated n-alkanes; Perfluorinated alkyl acids; ski waxes; snow; soil; fate; NATURAL SCIENCES; NATURVETENSKAP; Applied Environmental Science; tillämpad miljövetenskap;

   Sammanfattning : Highly fluorinated organic compounds are emerging environmental contaminants of concern, due to their persistence, ubiquitous distribution, bioaccumulation potential and toxicity. Ski waxes are sources of highly fluorinated chemicals to the environment that have not been investigated so far. LÄS MER
