  1. 6. Effects of early life exposure to flutamide on sexual development in Xenopus tropicalis

    University essay from Uppsala universitet/Institutionen för biologisk grundutbildning; Uppsala universitet/Miljötoxikologi

    Author : Christopher Hampton; [2019]
    Keywords : ;

    Abstract : While endocrine disrupting chemicals have become a serious concern in human and environmental toxicology, many of the methods used for investigating developmental toxicity require long exposure periods, and thus can be technically challenging, labour intensive and expensive. For example, the current standard method, the Larval Amphibian Growth and Development Assay (LAGDA) has an exposure period of ³130 days. READ MORE

  3. 7. Effect of perfluorononanoic acid (PFNA) on bovine early embryo development in vitro

    University essay from SLU/Dept. of Clinical Sciences

    Author : Jacklin Kjellgren; [2017]
    Keywords : bovine; embryo development; IVF; IVP; perfluorononanoic acid; PFNA; mitochondria; lipid; toxicity;

    Abstract : Perfluoroalkyl and polyfluoroalkyl substances (PFASs) is a large family of highly fluorinated chemicals, used in different commercial products (e.g. in clothing, shampoos, kitchenware and fire-fighting foams) utilizing their different properties, and have been found in wildlife, humans and in the environment.

  4. 8. Effects of Persistent Organic Pollutants and Their Mixtures on Biotransformation and Oxidative Stress in Zebrafish Embryo

    University essay from Örebro universitet/Institutionen för naturvetenskap och teknik

    Author : Hyon Sun Jeong; [2016]
    Keywords : Zebrafish; Developmental toxicity; Mixture toxicity; Oxidative stress;

    Abstract : Persistent organic pollutants (POPs) cause significant effects on organisms due to their resistance to environmental degradation and specific toxic responses. Although POPs toxicities were linked to oxidative stress in the previous studies, there are few POPs studies that link them with oxidative stress in zebrafish during development. READ MORE

  5. 9. Metylkvicksilvers toxicitet

    University essay from SLU/Dept. of Biomedical Sciences and Veterinary Public Health

    Author : Harriet Noring; [2015]
    Keywords : metylkvicksilver; toxicitet; verkningsmekanism; behandling; methylmercury; toxicity; mechanism of action; treatment;

    Abstract : Metylkvicksilver (MeHg) är en form av tungmetallen kvicksilver och det är den form som är farligast för djur och människor. Det beror på dess organiska egenskaper som gör att det biomagnifieras genom födokedjan, effektivt absorberas från föda, distribueras till många organ, koncentreras i levande organismer, passerar blod-hjärnbarriären och ackumuleras, samt orsakar skador även vid låga doser.

  6. 10. Effects of perfluorinated compounds on hepatic fatty acid oxidation in avian embryos using a tritium release assay

    University essay from Örebro universitet/Akademin för naturvetenskap och teknik

    Author : Ola Westman; [2009]
    Keywords : PFOS; avian toxicology;

    Abstract : The large use of perfluorinated compounds (PFCs) to produce fluoropolymers in consumer and industrial applications, including insecticides, plastics, non-stick surfaces and fire fighting foams has led to a well known widespread occurrence and high concentrations are found in wild life including avian species. For instance, concentrations of perfluorooctane sulfonate (PFOS) in eggs from the common guillemot in the Baltic Sea are among the highest in the Nordic environment. READ MORE
