1. Understanding hazards of nanoplastics using Daphnia magna
Sammanfattning : This thesis presents the results of studies focused on effects caused by nano-sized particles using freshwater filter feeder Daphnia magna. I showed that both positively and negatively surface charged PS NPs induced significant mortality in D. magna after a life-time (103 days) of exposure at low concentrations. LÄS MER
2. Toxicogenomic responses in Daphnia magna
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
3. New Approaches for Daphnia magna Toxicity Assessment
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
4. Chlorinated Paraffins: improved understanding of their bioaccumulation and toxicity in Daphnia magna
Sammanfattning : Chlorinated paraffins (CPs) are industrial chemicals, mainly used as flame retardants, plasticizers and metal cutting fluids. Their production has reached historically high levels in the last decade, with an annual production exceeding one million tonnes. LÄS MER
5. Fungal degradation patterns and toxicity of furfurylated wood
Sammanfattning : The demand for timber products is increasing with global population and affluence. Concerns regarding conventionally used toxic wood preservatives and the deforestation of tropical forests have become more prominent both socially and politically. Wood based products are generally recognised as an environmentally favourable raw material. LÄS MER
