  1. 1. Computational Ecotoxicology

    Författare :Sergio Manzetti; David Van der Spoel; Janez Mavri; Uppsala universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; pollutants; simulation; molecular; dynamic; quantum; chemistry; Biology with specialization in Molecular Biotechnology; Biologi med inriktning mot molekylär bioteknik;

    Sammanfattning : Human society has progressed by polluting ecosystems since at least the early industrial revolution. Large amounts of harmful chemical compounds have been dispersed in soils, seas, ground waters and wildlife habitats by industrial and anthropomorphic activities over the last two centuries, leading to a persistent toxicological load on the environment.

  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. Damsel in distress – metabolomics as a novel tool to investigate the effects of wastewater exposure on damselfly larvae

    Författare :Jana Späth; Malin L. Nording; Jerker Fick; Stina Jansson; Tuulia Hyötyläinen; Umeå universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; biomarkers; ecotoxicology; invertebrates; GC-MS; LC-MS; LC-MS MS; metabolomics; micropollutants; pharmaceuticals; risk assessment; ekotoxikologi; Ecotoxicology; Analytical Chemistry; analytisk kemi;

    Sammanfattning : Aquatic organisms, such as aquatic invertebrates, are exposed to anthropogenic pollutants through their environment. These pollutants, despite their low levels, can adversely affect exposed individuals or even entire ecosystems, especially when present in complex mixtures. LÄS MER

  5. 5. 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; []

    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.
