    Sammanfattning : Aquatic organisms are constantly at risk of being exposed to potentially harmful chemical compounds of natural or anthropogenic origin. Biological life can for instance respond to chemical stressors by changes in gene expression, and thus, certain gene transcripts can potentially function as biomarkers, i.e. LÄS MER

  3. 27. Towards Sustainable Use of Chemicals in the Textile Industry: How life cycle assessment can contribute

    Författare :Sandra Roos; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Toxicity; Textile; LCA; Chemicals; Impact assessment;

    Sammanfattning : The use of chemicals in the textile industry is a topic that has been given increasing attention in recent years. Hazardous chemicals are found in textile consumer products on a regular basis, and there is an increased awareness of the health and environmental impact caused by emissions of hazardous chemicals in the countries where textile production occurs.

  4. 28. Ecological implications of the production of toxic substances by fish killing phytoplankton species grown under variable N:P-ratios

    Författare :Niclas Johansson; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; mixotrophy; grazing; allelopathic interactions; allelopathy; algae; phytoplankton; nutrient limitation; toxicity; Toxic haptophytes; fishkilling phytoplankton; Hydrobiology; marine biology; aquatic ecology; limnology; Marinbiologi; limnologi; akvatisk ekologi;

    Sammanfattning : The influence of different nutrient conditions on the production of toxins was studied in certain fishkilling haptophytes (e.g. Prymnesium parvum and Chrysochromulina polylepis). LÄS MER

  5. 29. Quality of life and psychological reactions in women on first line chemotherapy for metastatic breast cancer - Correlations to tumour response and predictive factors

    Författare :Helene Svensson; Göteborgs universitet; []
    Nyckelord :Breast cancer; Recurrence; Health-related quality of life; EORTC QLQ-C30; Metastatic breast cancer; Prognostic factors; Chemotherapy; Toxicity; SNP; Psychological reactions;

    Sammanfattning : Background: Health-related quality of life (HRQoL) is an important endpoint in clinical trials and as an aspect that must be considered in the treatment of patients with metastatic breast cancer. Treatment efficacy and toxicity are important factors for HRQoL, so it is imperative to study the effects of oncological treatment in terms of HRQoL. LÄS MER

  7. 30. Heavy metal contamination and toxicity : Studies of Macroalgae from the Tanzanian Coast

    Författare :Florence Alex Mamboya; Mats Björk; Nils Ekelund; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Heavy metals; Padina gymnospora; Ulva reticulata; salinity; nutrients; proteins; uptake; growth; Fv Fm; Zanzibar Channel; Plant physiology; Växtfysiologi; växtfysiologi; Plant Physiology;

    Sammanfattning : Concentrations of various metals are elevated above background levels in several intertidal areas along the Tanzanian coasts. However, there is little available information concerning the toxicity of these metals and how the uptake of these metals by bioindicators are influenced by external factors, such as heavy rains and increased coastal eutrophication, which tend to fluctuate.
