1. 41. Cumulative assessment of persistent organic pollutant toxicity in vivo

   Författare :Emma Westerholm; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :;

   Sammanfattning : Humans are continuously exposed to a multitude of compounds present in the environment and in food. A major challenge in risk assessment is to determine the degree of exposure to multiple chemicals and the hazards associated with such combined exposure. LÄS MER

3. 42. Epidemiological aspects on malignant diseases in childhood

   Författare :Ann Charlotte Dreifaldt; Lennart Hardell; Ulf Flodin; Örebro universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; childhood cancer; incidence rates; persistent organic pollutants; breast-feeding; MEDICINE; MEDICIN; Oncology; Onkologi; Medicin; Medicine; Onkologi; Oncology;

   Sammanfattning : The trends of malignant diseases in children aged 0 to 14 years, reported to the Swedish Cancer Registry 1960–1998 (n=9 298) were analyzed. The most common diagnoses were leukemia, 29.7%, tumors of the central nervous system (CNS), 27.6%, and lymphomas, 10. LÄS MER

4. 43. Methods to measure mass transfer kinetics, partition ratios and atmospheric fluxes of organic chemicals in forest systems

   Författare :Damien Johann Bolinius; Annika Jahnke; Matthew MacLeod; Michael McLachlan; Antonio Di Guardo; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Hydrophobic organic chemicals; vegetation; modified Bowen ratio; surface-atmosphere fluxes; Applied Environmental Science; tillämpad miljövetenskap;

   Sammanfattning : Vegetation plays an important role in the partitioning, transport and fate of hydrophobic organic contaminants (HOCs) in the environment. This thesis aimed at addressing two key knowledge gaps in our understanding of how plants exchange HOCs with the atmosphere: (1) To improve our understanding of the uptake of HOCs into, and transfer through, leaves of different plant species which can significantly influence the transport and fate of HOCs in the environment; and (2) To evaluate an experimental approach to measure fluxes of HOCs in the field.

5. 44. The role of personligt ombud in supporting the recovery process for people with psychiatric disabilities

   Författare :Carolina Klockmo; Sven Uno Marnetoft; Mikael Nordenmark; John Selander; Urban Markström; Mittuniversitetet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; case management; psychiatric disabilities; recovery; rehabilitation;

   Sammanfattning : The overall aim was to explore the experiences and knowledge of Personligt Ombud (PO) (a Swedish version of Case Management) and how they relate to the client's recovery as well as their own role of supporting clients in the recovery process. The thesis consists of four original papers (I-IV), and both quantitative and qualitative methods were used. LÄS MER

7. 45. 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).
