   Författare :Deguo Kong; Ian Cousins; Matthew MacLeod; Mick Whelan; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; emerging chemicals; climate change; fate; multimedia model; risk assessment; physical-chemical property; uncertainty; Arctic; Baltic; time series; persistent organic pollutants; temporal trend; Applied Environmental Science; tillämpad miljövetenskap;

   Sammanfattning : Both chemical-specific (e.g. physical-chemical properties) and environmental (e.g. LÄS MER

3. 2. Organohalogen contaminants in Greenland shark (Somniosus microcephalus)

   Författare :Anna Strid; Åke Bergman; Maria Athanasiadou; Shinsuke Tanabe; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; persistent organic pollutants; sub-Arctic; Iceland; shark; Environmental chemistry; Miljökemi; miljökemi; Environmental Chemistry;

   Sammanfattning : The remote sub-Arctic/Arctic environment has due to human activities become a sink for organohalogen contaminants (OHCs). These OHC include traditional contaminants such as polychlorinated biphenyls (PCBs), DDTs and technical mixtures of polybrominated diphenyl ethers (PBDEs), all included in the Stockholm Convention list of persistent organic pollutants (POPs).

4. 3. Temporal and spatial trends of organohalogens in guillemot (Uria aalge) from North Western Europe

   Författare :Hrönn Jörundsdóttir; Åke Bergman; Derek Muir; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Arctic; environmental; monitoring; pollution; time trends; spatial trends; Environmental chemistry; Miljökemi; Environmental Chemistry; miljökemi;

   Sammanfattning : The Arctic and sub-Arctic region of the North Atlantic is a remote area, also in relations to environmental contaminants, such as POPs, BFRs and last but not least, PFCs. Both the BFRs and PFCs are considered emerging pollutants of significant environmental concern. LÄS MER

5. 4. In silico methods to prioritize chemicals with high exposure potential

   Författare :Efstathios Reppas Chrysovitsinos; Matthew MacLeod; Anna Sobek; Michael Matthies; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; free energy relationship; solvation parameters; polymers; materials; partitioning; octanol; Arctic contaminants; AMAP; POPs; Stockholm Convention; vPvB; REACH; OECD; QSAR; planetary boundaries; persistence; bioaccumulation; long-range transport; Applied Environmental Science; tillämpad miljövetenskap;

   Sammanfattning : Chemicals offer a wide range of desired functions and are used in a variety of consumer goods and industrial sectors. The number of individual synthetic organic chemicals produced and the total global chemical production volume are increasing. LÄS MER

7. 5. Legacy persistent organic pollutants and chemicals of emerging concern in Sweden : from indoor environments to remote areas

   Författare :Seth Newton; Cynthia de Wit; Ulla Sellström; Per Larsson; Annika Jahnke; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; persistent organic pollutants; atmospheric deposition; arctic; flame retardant; POP; long range transport; miljökemi; Environmental Chemistry;

   Sammanfattning : Bulk atmospheric deposition samples were taken every two months for a year in 2009-2010 at two sites in northern Sweden and analyzed for a suite of legacy and emerging persistent organic chemicals including legacy organochlorine pesticides (OCPs), polychlorinated biphenyls (PCBs), polybrominated diphenyl ethers (PBDEs)  and novel flame retardants (NFRs).  To further investigate the urban occurrence and contribution to remote contamination of flame retardants, indoor air, ventilation system air, and dust were sampled in several microenvironments in Stockholm during the winter of 2012 for analysis of PBDEs, isomer-specific hexabromocyclododecane (HBCDD), and NFRs.
