  4. 4. 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
