  1. 1. The effects of exposure to microplastics and pollutants on the arthropod microbiome

    Författare :Javier Edo Varg; Richard Svanbäck; Jarone Pinhassi; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; ecotoxicology; host microbiota; freshwater; anthropogenic pollution; microplastics; pesticides; pyrethroids; detergents; toxic metals; daphnids; chironomids; water boatmen; damselflies; dragonflies;

    Sammanfattning : Anthropogenic pollution is widespread across various ecosystems. This disturbance can alter the interaction between a host and its associated microbiome, with repercussions for hosts traits such as health, behavior, and host evolution. LÄS MER

  3. 2. Microplastics in the aquatic environment: Insights into biological fate and effects in fish

    Författare :Giedrė Ašmonaitė; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; microplastics; nanoplastics; plastic pollution; effects; fish; chemical mixtures; ecotoxicology;

    Sammanfattning : According to the United Nations, plastic pollution in the natural environment has been identified as one of the biggest environmental challenges of this century and has become a cause for an emerging international concern. It has been predicted that up to 12 million tons of plastic waste reach the aquatic environment annually. LÄS MER

  4. 3. Microplastics in the marine environment and the assessment of potential adverse effects of associated chemicals

    Författare :Christine Schönlau; Anna Kärrman; Magnus Engwall; Magnus Breitholtz; Örebro universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Microplastics; reporter gene bioassays; sorption; HOCs; polyethylene; polypropylene; polystyrene;

    Sammanfattning : During the last decade plastics have gained interest by scientists as emerging pollutants particularly in the marine environment due to their ubiquity and persistence. While several studies report the occurrence of microplastics in surface waters globally, there are no harmonized methods to sample and measure microplastics, and the knowledge of toxicological effects in the marine ecosystem is scarce.

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

    Författare :Warren Kunce; Frank Johansson; Jan Örberg; Sarah Josefsson; Jes Rasmussen; Uppsala universitet; []
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

  7. 5. Sources and fate of plastic particles in northern European coastal waters

    Författare :Therese Karlsson; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; plastic pollution; microplastics; method development; polyethylene; FTIR spectroscopy;

    Sammanfattning : Plastics are integral parts of our lives and have allowed for important technological leaps within society. However, an unwanted consequence of our current consumption of plas-tics is marine plastic pollution and in order to reduce its impact we need to understand its sources and fate patterns. LÄS MER
