  1. 1. Understanding hazards of nanoplastics using Daphnia magna

    Författare :Egle Kelpsiene; NanoLund: Centre for Nanoscience; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Daphnia magna; nanoplastics; polystyrene; polylactic acid nanoparticles;

    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

  3. 2. Encounters at the microscale: Unraveling soil microbial interactions with nanoplastics

    Författare :P. Micaela Mafla-Endara; MEMEG; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Microfluidic devices; Nanoplastics; Soil microorganisms; Toxicity;

    Sammanfattning : Nanoplastics (NPs) originated from plastic residues can interact with soil microorganisms with potential negative effects to their functions. Therefore, I aimed to investigate soil microbial population dynamics when exposed to different NP polymers and concentrations. LÄS MER

  4. 3. 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
