  1. 1. Effects of early exposure to fluoxetine on behavioural development in zebrafish

    University essay from Uppsala universitet/Institutionen för biologisk grundutbildning

    Author : Moa Forssten; [2024]
    Keywords : Fluoxetine; zebrafish; development; behaviour;

    Abstract : Many pharmaceuticals are stable molecules and after human excretion they enter the wastewater facilities where roughly 60 % is removed. The remaining residues will affect the concentration in close by streams and at the effluent, where fish like to spawn. Therefore, the development and behaviour of aquatic life is potentially at risk. READ MORE

  3. 2. Acclimatisation of rats before scientific experiments

    University essay from SLU/Dept. of Clinical Sciences

    Author : Viktoria Brånsgård; [2023]
    Keywords : acclimatisation; acclimatisation period; rat; transportation; stress; corticosterone;

    Abstract : The most common laboratory animals in Sweden today are mice, rats, and zebrafish. We sent out an anonymous digital survey to investigate if scientific facilities in Sweden acclimatise their rats after transportation, how long the acclimatisation time is, and how the acclimatisation is conducted.

  4. 3. An Investigation of The Link Between Endocrine Disruption and Developmental Neurotoxicity Induced by Environmental Pollutants : In Zebrafish Embryos

    University essay from Uppsala universitet/Institutionen för cell- och molekylärbiologi; Uppsala universitet/Institutionen för biologisk grundutbildning

    Author : Maria Revenikioti; [2023]
    Keywords : Endocrine-disrupting chemical EDC ; Environmental pollutants; Endocrine disruption ED ; Developmental neurotoxicity DNT ; Development; Zebrafish embryos; Estradiol; DHT; BPF; PFOS.;

    Abstract : Endocrine-disrupting chemicals (EDCs) are known to cause endocrine disruption (ED), developmental neurotoxicity (DNT), infertility and impaired embryo development. EDCs do therefore impose a threat to humans, wildlife and the environment. READ MORE

  5. 4. 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

  6. 5. EFFECT OF ENDOCRINE DISRUPTING MIXTURES AND CHEMICALS ON THE OXYGEN CONSUMPTION RATE OF ZEBRAFISH LARVAE

    University essay from Göteborgs universitet / Institutionen för biologi och miljövetenskap

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

    Abstract : 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.
