  1. 1. Characterization of xenobiotic metabolism in the feral teleost northern pike (Esox lucius)

    Författare :Lennart Balk; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : A basic characterization of xenobiotic metabolism in the feral teleost Northern pike has been performed. The different aspects of concern have been:a) investigation of the uptake and distribution to different body compartments of the carcinogen and environmental pollutant benzo(a)pyrene using whole-body autoradiography and scintillation counting.

  3. 2. Biomarkers in perch (Perca fluviatilis) used in environmental monitoring of the Stockholm recipient and background areas in the Baltic Sea

    Författare :Tomas Hansson; Lennart Balk; Ulf Rannug; Tracy Collier; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; biomarker; DDT; environmental monitoring; EROD; fish; GSI; nanoinjection; PAH; PCB; Perca fluviatilis; perch; reproduction; Environmental toxicology; Miljötoxikologi; Applied Environmental Science; tillämpad miljövetenskap;

    Sammanfattning : This thesis reports the results of biomarker measurements in three environmental monitoring projects. In the first project, which was part of the Swedish national environmental monitoring, biomarkers were measured annually in female perch (Perca fluviatilis) in two background areas in the Baltic Sea during 1988–2000, resulting in a unique 13-year series of measurements.

  4. 3. Biochemical characterisation of landfill leachate toxicity in fish

    Författare :Maria Linderoth; Lennart Balk; Ulf Rannug; Cinta Porte Visa; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; landfill leachate; endocrine disruption; fish; Environmental toxicology; Miljötoxikologi;

    Sammanfattning : Deposition remains the most common form of waste disposal in many parts of the world. As a terminus of the products consumed in our society a landfill may contain virtually all sorts of man-made chemicals. Despite this, the harmfulness of landfill leachate has not been extensively evaluated in feral organisms in the environment. LÄS MER

  5. 4. Environmental Monitoring of Refuse Dump Leachate Toxicity in Fish

    Författare :Erik Noaksson; Lennart Balk; Louis J. Guillette Jr; Stockholms universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Fiskar; miljögifter; Toxicology; Toxikologi;

    Sammanfattning : The global economy is driven by the consumption of goods and materials. Used products are often deposited on refuse dumps, making them potential point sources for all man-made chemicals. Water soaking through landfill waste results in a wastewater termed leachate. LÄS MER

  7. 5. Toxicological and Chemical Characterization of Organic Pollutants with Potential to Adversely Affect Fish

    Författare :Henrik Sundberg; Lennart Balk; Dag Broman; Tracy Collier; Stockholms universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Toxicology; Toxikologi;

    Sammanfattning : Several investigations have described adverse effects in fish inhabiting polluted areas, though the causative, or aetiologic compounds have not been substantiated. Since environmental pollutants exist as complex mixtures, reliable risk estimations are difficult to obtain. LÄS MER
