3. 7. Androgenic Effects of the Progestin Levonorgestrel in Three-spined Stickleback (Gasterosteus aculatus)

   Författare :Johan Svensson; Björn Brunström; Ingvar Brandt; Emma Wincent; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biologi med inriktning mot ekotoxikologi; Biology with specialization in Environmental Toxicology;

   Sammanfattning : The extensive use of pharmaceuticals and their poor removal by wastewater treatment plants has led to the emergence of pharmaceutical compounds as global aquatic contaminants. Progestins, the synthetic analogues to progesterone, are receiving increasing attention as contaminants and have been shown to impair reproduction in fish and amphibians at low ng L-1 concentrations.

   Sammanfattning : The extensive use of pharmaceuticals and their poor removal by wastewater treatment plants has led to the emergence of pharmaceutical compounds as global aquatic contaminants. Progestins, the synthetic analogues to progesterone (P4), are receiving increasing attention as contaminants and have been shown to impair reproduction in fish and amphibians at low ng L-1 concentrations.
