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

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Johan Svensson; Uppsala universitet.; [2016]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Pharmaceuticals as contaminants; Progestins; Androgenic properties; Fish; Biologi med inriktning mot ekotoxikologi; Biology with specialization in Environmental Toxicology;

    Abstract : 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.

  2. 2. Cellular transport and secretion of the cyanobacterial neurotoxin BMAA into milk and egg Implications for developmental neurotoxicity

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Marie Andersson; Uppsala universitet.; [2015]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; BMAA; beta-N-methylamino-L-alanine; milk; secretion; amino acid transporter; autoradiography; metabolism; Biologi med inriktning mot ekotoxikologi; Biology with specialization in Environmental Toxicology;

    Abstract : The cyanobacterial amino acid β-N-methylamino-L-alanine (BMAA) is a neurotoxin implicated in the etiology of neurodegenerative diseases. Cyanobacteria are cosmopolitan organisms present in various environments. READ MORE

  3. 3. Azoles and Contaminants in Treated Effluents Interact with CYP1 and CYP19 in Fish

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Kristina Beijer; Uppsala universitet.; [2015]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Azole; fungicide; chemical; CYP1A; CYP19; EROD; aromatase; effluent; STP; wastewater; fish; stickleback; rainbow trout; Biologi med inriktning mot ekotoxikologi; Biology with specialization in Environmental Toxicology;

    Abstract : Numerous contaminants are present in mixtures in the aquatic environment. Among these are the azoles, a group of chemicals that includes both pharmaceuticals and pesticides. Azole fungicides are designed to inhibit lanosterol 14-demethylase (cytochrome P450 (CYP) 51), while other azoles are intended to inhibit aromatase (CYP19), i.e. READ MORE

  4. 4. The Otter (Lutra lutra) in Sweden Contaminants and Health

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Anna Roos; Uppsala universitet.; [2013]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Otter Lutra lutra ; PCB; DDT; PFAAs; reproduction; bone; time trends; Biologi med inriktning mot ekotoxikologi; Biology with specialization in Environmental Toxicology;

    Abstract : In the 1950s the otter started to decline in numbers and distribution in Sweden and other parts of Europe. In 1972 a game law came into force, listing otter as a species that if found dead should be reported and sent to the authorities. The numbers of dead otters reported from different areas indicate population status and distribution. READ MORE
