3. 2. Chemical reactivities as a mirror of environmental transformations - method development and assessment of some selected organohalogens

   Författare :Lisa Granelli; Åke Bergman; Johan Eriksson; Roland Kallenborn; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Environmental chemistry; Miljökemi; miljökemi; Environmental Chemistry;

   Sammanfattning : The assement of chemical persistence is an important part of legislative protection of the environment and human health. Of the vast number of chemicals on the market today few have been properly assessed. LÄS MER

4. 3. Toxicologically important DDT metabolites : Synthesis, enantioselective analysis and kinetics

   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; o; p -DDD; 3-Methylsulfonyl-DDE; adrenocorticolytic compounds; chiral; Environmental chemistry; Miljökemi; Environmental Chemistry; miljökemi;

   Sammanfattning : DDT was extensively and globally used as a pesticide in agriculture and for malaria vector control from the 1940’s until the 1970’s. Due to its heavy use, DDT became ubiquitously distributed throughout the environment. DDT and several DDT metabolites are persistent organic pollutants. LÄS MER

5. 4. Synthesis of highly brominated diphenyl ethers and aspects on photolysis and indoor spreading

   Sammanfattning : Adding chemicals to materials to decrease flammability can be dated back to as early as 450 BC when the Egyptians used alum to reduce flammability of wood. Almost 2500 years later brominated flame retardants (BFRs) are used to prevent ignition of textiles, electronics and polymers. LÄS MER

7. 5. Environmentally relevant chemical disruptors of oxidative phosphorylation in Baltic Sea biota : Exposure and toxic potentials

   Författare :Anna-Karin Dahlberg; Lillemor Asplund; Åke Bergman; Göran Marsh; Patrik Andersson; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Oxidative phosphorylation; OH-PBDEs; MeO-PBDEs; PBDEs; long-tailed duck Clangula hyemalis ; Baltic herring Clupea harengus ; Baltic blue mussel Mytilus trossulus x Mytilus edulis ; Baltic Sea; miljökemi; Environmental Chemistry;

   Sammanfattning : This thesis focuses on toxicity and occurrence of hydroxylated polybrominated diphenyl ethers (OH-PBDEs) in Baltic Sea biota. The aims were to assess OH-PBDEs potency for disruption of oxidative phosphorylation (OXPHOS) and determine their and related compounds exposure in Baltic blue mussel, herring and long-tailed duck.
