  1. 1. Computational Ecotoxicology

    Författare :Sergio Manzetti; David Van der Spoel; Janez Mavri; Uppsala universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; pollution; modeling; molecular; carcinogens; nanoparticles; quantum; chemistry; Chemistry with Specialisation in Theoretical Chemistry; Kemi med inriktning mot teoretisk kemi; Kemi med inriktning mot kvantkemi; Chemistry with specialization in Quantum Chemistry;

    Sammanfattning : Human society has progressed by polluting ecosystems since the early industrial revolution. Thus, large amounts of harmful chemical compounds have been dispersed in soils, seas, groundwaters and wildlife habitats, leading to a persistent toxicological load on the environment. LÄS MER

  2. 2. The fate and effect of pharmaceuticals in boreal surface waters

    Författare :Johan Fahlman; Jonatan Klaminder; Jan Karlsson; Fredrik Jutfelt; Umeå universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Aquatic ecosystems; behavioural effects; ecotoxicology; acoustic telemetry; field verification; social network; ekotoxikologi; Ecotoxicology; environmental science; miljövetenskap;

    Sammanfattning : Traces of pharmaceuticals are often found in streams, rivers, and lakes as the result of effluent water discharge. This dissertation aims to create a better understanding of the fate of drugs in aquatic ecosystems and how oxazepam, an anxiolytic pharmaceutical commonly detected in surface waters, affects the behavior of perch (Perca fluviatilis).

  3. 3. Selective serotonin re-uptake inhibitors in the environment : Effects of citalopram on fish behaviour

    Författare :Martin Kellner; Håkan Olsén; Inger Porsch-Hällström; Magnus Breitholtz; Södertörns högskola; []

    Sammanfattning : Selective serotonin re-uptake inhibitors (SSRIs) are a class of anxiolytic and anti-depressant drugs. SSRIs act on the evolutionarily ancient serotonergic system which is virtually identical throughout the vertebrate phylum. LÄS MER

  4. 4. Hazard assessment of ciprofloxacin, sulfamethoxazole and triclosan for marine periphyton : Ecotoxicology, Pollution Induced Community Tolerance and Co-Tolerance

    Författare :Henrik Johansson; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    Nyckelord :Ecotoxicology; Antibioitcs; Antimicrobial agents; Ciprofloxacin; Sulfamethoxazole; Triclosan; Community ecotoxicology; Periphyton; Toxicant-induced succession; Pollution-Induced Community Tolerance PICT ;

    Sammanfattning : Antibiotics and personal care products are used in large quantities and commonly detected in various environmental compartments. The two antibiotics, ciprofloxacin and sulfamethoxazole, and the personal care product triclosan are among the most commonly detected compounds in sewage treatment plants and aquatic environments.

  5. 5. The use of protein biomarkers in ecotoxicology : Studies of oxidative and genotoxic stress in the blue mussel (Mytilus edulis)

    Författare :Andreas Prevodnik; Michael Tedengren; Tomas Bollner; Kari Lehtonen; Stockholms universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; Biology; Biologi; Ecotoxicology; ekotoxikologi;

    Sammanfattning : Many environmental pollutants, heavy metals and polyaromatic hydrocarbons (PAHs) among them, are toxic by oxidative stress. Oxidative stress may be defined as a state in an organism when its inherent capacity to handle oxyradicals is surpassed, and it may result in peroxidation of lipids, and damage to proteins and DNA.
