1. Progestagenic Aquatic Contaminants Act as Potent Androgens in Fish : Experimental Studies in Three-spined Stickleback and Zebrafish
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.
