    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Risk assessment; toxicogenomics; zinc; copper; machine learning;

    Sammanfattning : Risk assessment plays a crucial role in evaluating and managing the potential hazards and health effects associated with exposure to substances. In recent decades, the field of risk assessment has undergone significant expansion, embracing innovative approaches and methodologies. LÄS MER

  3. 12. Gene expression and antibiotic resistance in Escherichia coli from Swedish inland waters

    Författare :Sirirat Poonlapthawee; Jana Jass; Per-Erik Olsson; Allan Sirsjö; Örebro universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Biology; Biologi;

    Sammanfattning : Extensive use of antibiotics both from human-medicine and veterinary sources are believed to provide selective pressure on bacteria that leads to an increase in antibiotic resistance in environmental waters. Contamination of antibiotic resistant microbes will raise human health risks. LÄS MER

  5. 14. Toxicogenomic responses in Daphnia magna

    Författare :Asmerom Seyoum; Per-Erik Olsson; Ajay Pradhan; Joachim Sturve; Örebro universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; ERA; organic pollutants; toxicogenomic; phthalate; PFAS and DBE-DBCH;

    Sammanfattning : Detection of various organic contaminants in the aquatic environment at low concentrations, has raised concerns for animal and human health. Structural similarities of these compounds to estrogens and ecdysones suggests that organic pollutants may interfere with hormonal system of aquatic organisms. LÄS MER

  7. 15. Habitat composition and restocking for conservation of the white-backed woodpecker in Sweden

    Författare :Kristoffer Stighäll; Per-Erik Olsson; Grzegorz Mikusinski; Örebro universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; White-backed woodpecker; Dendrocopos leucotos; Sweden; deciduous forest; suitable habitat; fragmentation; saproxylic insects; captive breeding; restocking; Biology; Biologi;

    Sammanfattning : In Sweden, intense human land use, especially forestry, has led to profound changes in the landscape over time, especially within the forest ecosystems. A consequence of this is that several specialist species have become endangered. One group of specialists is the woodpeckers. LÄS MER
