  1. 1. SINGLE AND COMBINED EXPOSURE OF POLYSTYRENE NANOPARTICLES AND NORTH SEA MARINE OIL IN TWO IN VITRO FISH MODELS

    University essay from Göteborgs universitet / Institutionen för biologi och miljövetenskap

    Author : Monica Olsson; [2022-10-05]
    Keywords : Polystyrene nanoparticles; crude oil; combined toxicity; cytotoxicity; oxidative stress;

    Abstract : The awareness of micro-and nanoplastic pollution and its impact on the marine ecosystem has increased over the last decade. Nanoplastics may affect aquatic organisms since their small size and high surface-to-volume ratio increases their bioavailability and ability to cross biological membranes. READ MORE

  3. 2. Characterization of PLA Nanoplastics, and Their Effects on Daphnia magna

    University essay from Lunds universitet/Centrum för analys och syntes

    Author : Melinda Rydberg; [2022]
    Keywords : Polylactic acid; Polylactide; PLA; Nanoplastic; Daphnia magna; Toxicity; Polymer Technology; Chemistry; Earth and Environmental Sciences;

    Abstract : As plastic pollution in aquatic environments keeps happening it has become more and more important to learn more about nanoparticles. Bio-based and biologically degradable plastics, such as polylactic acid (PLA), are gaining popularity and it is therefore important to determine whether they break down into nanoplastics or not.

  4. 3. PlaCo : The plastic collecting robot

    University essay from KTH/Mekatronik

    Author : Annie Persson; Johanna Bergsten; [2021]
    Keywords : Arduino; IR-sensor; marine debris; mechatronics; microplastics; ultrasonic sensor; Arduino; IR-sensor; marin nedskräpning; mekatronik; mikroplaster; ultraljudssensor;

    Abstract : The oceans are an essential global resource for all living organisms but especially for us humans. However, year after year we continue to neglect proper recycling of our waste, resulting in litter ending up in our oceans. The majority of said litter comes from single use plastic items. READ MORE

  5. 4. Nanoplastic transport in soils by advection and bioturbation

    University essay from SLU/Dept. of Soil and Environment

    Author : Wiebke Mareile Heinze; [2019]
    Keywords : column leaching; attachment efficiency; exposure; mixing rates; modelling;

    Abstract : Micro- and nanoplastics are increasingly perceived as an emerging threat to ecosystems. They are emitted to soils through different pathways, including sewage sludge or compost applications in agriculture, or through tire abrasion and degradation of mismanaged waste. READ MORE

  6. 5. Isolation of nanoplastics in fish from the North Aegean sea

    University essay from Lunds universitet/Tillämpad biokemi; Lunds universitet/Beräkningskemi

    Author : Isabella Gimskog; [2019]
    Keywords : nanoplastics; microplastics; Mediterranean; fish; isolation; applied biochemistry; tillämpad biokemi; Chemistry; Biology and Life Sciences; Earth and Environmental Sciences; Technology and Engineering;

    Abstract : The breakdown of plastics in our oceans is one of our times biggest challenges. What happens when these plastics are broken down into pieces too small to see is still a mystery. Nanoplastics is a relatively new area of research and much more studies need to be done before we can get a perspective of how big the problem is. READ MORE
