  1. 1. Environmental intolerance : psychological risk and health factors

    Author : Eva Palmquist; Steven Nordin; Gregory Neely; Berndt Stenberg; Michael Witthöft; Umeå universitet; []
    Keywords : SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Environmental intolerance; stress; anxiety; depression; burnout; prognosis; recovery; spreading; coping; social support; co-prevalence; Västerbotten Environmental Health Study; idiopathic environmental intolerance; multiple chemical sensitivity; sick building syndrome; noise sensitivity; electromagnetic hypersensitivity; Psychology; psykologi; Epidemiology; epidemiologi;

    Abstract : Environmental intolerance (EI) is an embracing term for a number of conditions characterized by a wide range of non-specific symptoms attributed to certain environmental exposures (e.g. pungent/odorous chemicals, residing in a certain building, electromagnetic fields and everyday sounds). EI often leads to lifestyle alterations (e. READ MORE

  2. 2. Application and interpretation of biomarkers in ecotoxicology - from molecular to individual level responses

    Author : Sara Furuhagen; Elena Gorokhova; Carlos Barata; Stockholms universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; biomarkers; oxidative stress; ORAC; reproduction; Daphnia magna; toxicity; environmental stress; Applied Environmental Science; tillämpad miljövetenskap;

    Abstract : The use of biomarkers is considered a promising alternative, or complement, to traditional ecotoxicological assays. Toxic effects are often initially manifested at the molecular or biochemical level, biomarkers are therefore used as sensitive indicators of toxic exposure. READ MORE

  3. 3. 3-D numerical modeling of flow and sediment transport in rivers

    Author : Muluneh Admass; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Environmental technology; River model; ECOMSED model; River Klarälven; Bed load transport model; Miljöteknik; Environmental engineering; Miljöteknik;

    Abstract : The fully integrated 3-D, time dependant, hydrodynamic and sediment transport numerical model ECOMSED was used to simulate flow and sediment transport in rivers. ECOMSED was originally developed for large water bodies such as lakes and oceans and solves the primitive equations of RANS along with a second order turbulence model in an orthogonal curvilinear σ- coordinate system.

  4. 4. Fish bile in environmental analysis

    Author : Margaretha Adolfsson-Erici; Michael McLachlan; Lillemor Asplund; Freek Ariese; Stockholms universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; fish bile estrogenic triclosan rubber additives pulp and paper; Environmental chemistry; Miljökemi;

    Abstract : This work explores the usefulness of fish bile analysis in combination with biomarkers for identifying and evaluating new environmental contaminants in the aquatic environment. It illustrates how bile analysis can be used together with biomarkers to assess the causes of estrogenic effects, to identify chemicals in the aquatic environment that are taken up by fish, and to monitor environmental exposure.

  5. 5. Coping with environmental stress : from the individual and population perspective

    Author : Johanna Gardeström; Michael Tedengren; Tina Elfwing; Mats Grahn; Gary Carvalho; Stockholms universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Environmental stress; Genetic diversity; Multi-level approach; Invertebrates; Marine ecology; Marin ekologi; Systems Ecology; systemekologi;

    Abstract : Natural stress and disturbances are important factors affecting the structure and function of ecosystems. However the magnitude of stress has escalated due to anthropogenic activities. Environmental monitoring and toxicity assessments try to protect ecosystems from unwanted human alterations. READ MORE
