2. 1. Uptake and toxicity of brominated flame retardants and pesticides : Studies on littoral organisms and model communities

   Author : Kerstin Gustafsson; Nils Kautsky; Kirsten Christoffersen; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; aquatic ecotoxicology; ecological interactions; indirect effects; model community studies; toxicity; Terrestrial; freshwater and marine ecology; Terrestisk; limnisk och marin ekologi;

   Abstract : In this thesis, brackish and freshwater littoral model communities (microcosms) of varying size and complexity were used to study the effects of brominated flame retardants (BFRs) and pesticides. The brackish water microcosms consisted of natural water, sediment and associated organisms, while the larger freshwater microcosms also contained submersed macrophytes (Elodea canadensis).

4. 2. Semipermeable membrane devices in monitoring of organic pollutants in the aquatic environment

   Author : Darius Sabaliunas; Biologiska institutionen; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; effect studies; environmental monitoring; organic pollutants; bioconcentration; passive samplers; Semipermeable membrane devices; SPMDs; toxicity; genotoxicity; bioassays; Ecology; Ekologi;

   Abstract : Semipermeable membrane devices (SPMDs) are passive samplers capable of concentrating hydrophobic chemicals from water, sediments, soil and air. They consist of layflat polymeric membrane such as polyethylene containing a thin film of synthetic lipid such as triolein. READ MORE

5. 3. Sub-lethal Effects of Anthropogenic Contaminants on Aquatic Invertebrates

   Author : Warren Kunce; Frank Johansson; Jan Örberg; Sarah Josefsson; Jes Rasmussen; Uppsala universitet; []
   Keywords : ecotoxicology; sub-lethal; behavior; biomarkers; thermal tolerance; pesticides; pyrethroids; neonicotinoids; pharmaceuticals; antihistamines; microplastics; mixtures; freshwater; invertebrates; chironomids; damselflies; snails; Biology with specialization in Animal Conservation; Biologi med inriktning mot zoologisk bevarandebiologi;

   Abstract : Anthropogenic contaminants are considered to play a substantial role in the decline of freshwater invertebrate diversity. Sub-lethal effects of many of these contaminants on behaviour and life-history traits of aquatic invertebrates may contribute to their decline. READ MORE

6. 4. Natural enemies: Functional aspects of local management in agricultural landscapes

   Author : Helena Hanson; Biodiversitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Agricultural intensification; sustainable agriculture; land use; management intensity; landscape scale; ecosystem services; biological control; species trait; pesticides; predatory arthropods; parasitoids; pollen beetles;

   Abstract : Agricultural intensification has raised the global food production but also caused major concerns about environmental and health effects, including contamination by pesticides. Pesticide applications may induce toxicity not only on the target pest species but especially on non-target species. READ MORE

7. 5. Protecting food with poison : Exploring ecotoxicity of agrochemicals and pharmaceuticals

   Author : Oskar Nyberg; Michael Tedengren; Peter Fantke; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; LCA; ecotoxicology; uncertainty; antibiotics; aquaculture; pesticides; Ecotoxicology; ekotoxikologi;

   Abstract : Chemicals are being emitted into the environment through human activities, such as agriculture or animal husbandry. Emissions can either occur intentionally, as pesticide application of crops, or inadvertently, such as pharmaceutical residues in wastewater effluents. READ MORE
