  1. 31. Assessment of environmental contaminants’ neurotoxicity : in vitro and in vivo experimental studies

    Författare :Wan Norhamidah Wan Ibrahim; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Accumulating evidence points to environmental contaminants as possible causes of neuronal damage in developing organisms. A prerequisite to prevention is the recognition of a chemical’s harmful effects during development. LÄS MER

  3. 32. Distribution and fate of polychlorinated biphenyls within the pelagic microbial food web

    Författare :Petra Wallberg; Per Larsson; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biology; Biologi; zoologi; Zoology;

    Sammanfattning : The composition and production of the plankton community in aquatic environments will in turn influence the food-web structure of larger predators, nutrient cycling, the sinking flux and, hence, the fate of hydrophobic organic contaminants. The aim of the research presented here was to study the distribution and fate of PCBs within the microbial food web, including bacteria, flagellates, ciliates, and phytoplankton. LÄS MER

  4. 33. Bis(4-chlorophenyl) sulfone and PCB methyl sulfone metabolites : Trends and chirality in the Baltic Sea environment

    Författare :Karin Norström; Åke Bergman; Mats Olsson; Roland Kallenborn; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; bis 4-chlorophenyl sulfone; PCB methyl sulfone; Baltic Sea; Environmental chemistry; Miljökemi;

    Sammanfattning : The Baltic Sea was earlier identified as a highly polluted brackish water body and still is. The high concentrations of polychlorinated biphenyls (PCBs), p,p’-DDT and related compounds led to severe effects on several species in the Baltic region. LÄS MER

  5. 34. Human exposure to organohalogen compounds in the Faroe Islands

    Författare :Britta Fängström; Åke Bergman; Jake Ryan; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; PCB; PBDE; OH-PCB; human serum; Environmental chemistry; Miljökemi;

    Sammanfattning : The Faroe Islands in the North Atlantic are part of the sub-Arctic region, a remote region far from industrial activity. In spite of this remoteness, the Islands are not a sanctuary: exposures and effects of environmental pollutants mar its natural beauty and wildlife. LÄS MER

  7. 35. Persistent organic pollutants in Swedish first-time mothers and effects on infant health

    Författare :Sanna Lignell; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Humans are exposed to a variety of persistent organic pollutants (POPs) that have been spread to the environment because of various human activities. Food is the main source of exposure to most POPs. Many POPs are lipid-soluble, accumulate in the human body and are easily transferred to the fetus and to breastfed infants through breast milk.
