  1. 1. A review on ozonation and17a-ethinylestradiol - formation and effects in the environment of the by-products

    University essay from Lunds universitet/Miljövetenskaplig utbildning

    Author : Erica Svensson; [2017]
    Keywords : Ethinylestradiol; EE2; By-products; Ozonation products; Transformation products; Ozonation; Earth and Environmental Sciences;

    Abstract : Today, waste water treatment plants do not remove pharmaceutical residues from the water (as there are currently no regulations for wastewater treatment in regards to pharmaceuticals residues in Sweden) resulting in a high concentration of pharmaceuticals reaching the environment. The Swedish environmental protection agency have recently concluded that there is a need for advanced treatment of pharmaceuticals in wastewater. READ MORE

  2. 2. Combination of nanoparticles from polystyrene and the hormone 17alpha-ethinylestradiol (EE2) in water.

    University essay from Lunds universitet/Miljövetenskaplig utbildning

    Author : Emma Nilsson; [2017]
    Keywords : water; nanoparticles; hormons; Plastic; Earth and Environmental Sciences;

    Abstract : Plastic materials and synthetic hormones are found in aquatic environments globally. Plastic in water can degrade to nanoparticles (NP) with special characteristics, in the environment nanoparticles and hormones have a proven effect on wildlife. READ MORE

  3. 3. Initial evaluation of the combined effects of nanoplastics and 17α-ethinylestradiol on D. magna

    University essay from Lunds universitet/Miljövetenskaplig utbildning

    Author : Tobias Henriksson; [2017]
    Keywords : daphnia magna nanoplastics nanoparticles 17α-ethinylestradiol ethinylestradiol combined effects; Earth and Environmental Sciences;

    Abstract : Exposure of combined pollutants is as of today not a very well-researched field of environmental science due to the complex interactions that may occur. Nanoplastic particles (NP) in particular are lacking studies due to the relatively new interest in the subject. READ MORE

  4. 4. The estrogen receptor in the freshwater pulmonate gastropod Radix balthica: Investigating changing activity levels from exposure to 17α -ethinylestradiol

    University essay from Lunds universitet/Miljövetenskaplig utbildning

    Author : Lina Börjesson; [2012]
    Keywords : Earth and Environmental Sciences;

    Abstract : Endocrine disruption from synthetic human estrogens in molluscs has not been investigated as closely as in vertebrates. This has led to a missing piece in the important puzzle investigating the differences in effects between diverse animal groups after exposure to endocrine disrupting chemicals, EDCs. READ MORE

  5. 5. The Effect of Synthetic Estrogen on Foraging and Predator Avoidance in the Common Roach (Rutilus rutilus)

    University essay from Lunds universitet/Miljövetenskaplig utbildning

    Author : Gustaf Boström; [2012]
    Keywords : EE2; ecotoxicology; roach; rutilus; foraging; predator avoidance; Biology and Life Sciences;

    Abstract : Synthetic estrogens that originate mainly from oral contraceptive pills reach our waters through sewage effluent and potentially affect organisms in the natural environment. This study focused on the effects of the synthetic estrogen 17-alpha-ethinylestradiol (EE2) on the foraging and predator avoidance behaviors of the planktivorous fish roach (Rutilus rutilus), a common fish in Swedish lakes and rivers.
