  1. 1. Risk assessment of non-intentionally added substances in polyester yarn made from recycled polyethylene terephthalate (PET)

    Uppsats för yrkesexamina på grundnivå, KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Författare :Kristina Arnqvist; [2023]
    Nyckelord :r-PET; polyester yarn; NIAS; risk assessment;

    Sammanfattning : Polyester is a synthetic material made from polyethylene terephthalate (PET), which is synthesised from fossil raw materials. Many clothing manufacturers are using polyester in their clothing, which, from an environmental perspective, creates a non-sustainable cycle. LÄS MER

  3. 2. EFFECT OF ENDOCRINE DISRUPTING MIXTURES AND CHEMICALS ON THE OXYGEN CONSUMPTION RATE OF ZEBRAFISH LARVAE

    Master-uppsats, Göteborgs universitet / Institutionen för biologi och miljövetenskap

    Författare :Lieke van Iersel; [2022-08-08]
    Nyckelord :oxygen consumption; zebrafish larvae; respirometry; endocrine disrupting chemicals; mixture toxicity;

    Sammanfattning : Chemicals affecting the endocrine system, so called endocrine disrupting chemicals (EDC’s), have been steadily increasing in the environment over the last 40 years. EDCs are harmful chemicals since they can act through multiple endocrine pathways, contain a wide spectrum of health effects that can be very persistent and can cause effects already at a low doses.

  4. 3. Problematik och möjligheter med återvinning av PVC-plast inom byggsektorn

    Kandidat-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknik

    Författare :Amelia Bågevik Gray; Elin Kjellberg; [2021]
    Nyckelord :PVC plastic; recycling; circular economy; PVC-plast; återvinning; cirkulär ekonomi;

    Sammanfattning : Studien baseras på en målkonflikt mellan att vilja ha en giftfri miljö och samtidigt sträva mot ett mer cirkulärt samhälle. Polyvinylklorid (fortsättningsvis PVC-plast) kan innehålla farliga ftalater som i för stor mängd kan vara skadliga för hälsa och miljö både under användning och återvinning. LÄS MER

  5. 4. Analysis of market and requirements of plasticizers for flexible PVC - With a focus on Perstorp’s non-phthalate plasticizer Pevalen

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Lisa Bywall; Sofie Cederlund; [2020]
    Nyckelord :PVC; plasticizer; plasticiser; industry; flexible PVC; polyvinylchloride; vinyl; flooring; chemical engineering; kemiteknik; Chemistry;

    Sammanfattning : Flexible Polyvinyl chloride (PVC) is a plastic material commonly used in today’s society and a fundamental material for a lot of sectors. It has advantages over other polymers such as energy-efficient production, flame retardancy, durability and cost-effective. LÄS MER

  7. 5. Effects of a phthalate mixture on Wnt/β-catenin signaling, apoptosis and metabolic rate in zebrafish embryos

    Master-uppsats, Uppsala universitet/Institutionen för biologisk grundutbildning

    Författare :Stavros Bountis; [2020]
    Nyckelord :phthalates; Wnt β-catenin signaling; apoptosis; zebrafish; metabolic rate;

    Sammanfattning : One of the most common plasticizers used in the production of plastic are phthalates. These chemicals have been associated with many adverse effects including developmental and reproductive anomalies. Early developmental processes targeted by chemicals can have long-lasting effects on individuals. LÄS MER
