1. Assessment of zebrafish embryo toxicity of environmentally relevant antibiotics
University essay from Uppsala universitet/Institutionen för medicinsk biokemi och mikrobiologiAbstract : Antibiotics are essential drugs in modern medicine. After consumption antibiotics are excreted in unmetabolized form in the urine and reach our sewage treatment plants (STP). STP are not able to degrade all antibiotics leading to release of antibiotics into the aquatic environment. Aquatic animals are thus continuously exposed to antibiotics. READ MORE

2. Coumarin 47 and permethrin effects on zebrafish embryos: : FET tests and behavioural challenges
University essay from Örebro universitet/Institutionen för naturvetenskap och teknikAbstract : An environment is defined as polluted when contaminants are introduced within it and causeadverse effects to its ecosystem. Chemical pollutants can migrate and often affect severalenvironmental compartments: for instance, chemicals can leach from polluted soil intogroundwater, or they can evaporate and disperse into the atmosphere.

3. Veterinary antiparasitic pharmaceuticals – effects on behaviour in fish larvae
University essay from SLU/Dept. of Biomedical Sciences and Veterinary Public HealthAbstract : SUMMARY Antiparasitic pharmaceuticals are important groups of pharmaceuticals in veterinary medicine and are used in large quantities. Antiparasitic pharmaceuticals and their metabolites enter the environment via excretion in urine and/or faeces from treated animals and by run off to surface water these compounds reach aquatic environments and thereby present a risk for aquatic organisms.

4. Teratogenic and Embryotoxic Effects of Polycyclic Aromatic Compounds Report
University essay from Örebro universitet/Institutionen för naturvetenskap och teknikAbstract : Polycyclic aromatic compounds are ubiquitously distributed pollutants in the aquatic and terrestrial environment containing harmful properties on creatures such as carcinogenicity, teratogenicity and toxicity, but are not so well analyzed yet. In the present study, the embryotoxic and teratogenic effects of selected hydroxylated and methylated PACs on the embryonal development of Danio rerio as an aquatic model organism were analyzed with the Fish Embryo Toxicity Test (FET) and the Tail Length Test (TLT) to obtain information on the toxic and teratogenic impact of the tested PACs on the environment.

5. The toxicological evaluation of Sewage Effluents and Pharmaceuticals with the use of Zebrafish as a model organism
University essay from SLU/Dept. of Biomedical Sciences and Veterinary Public HealthAbstract : The presence of pharmaceuticals in the environment has been an issue of increasing concern and sewage treatment plants have been identified as the principal sources ofpharmaceuticals and endocrine disrupting chemicals in the aquatic environment.In this study, zebrafish juveniles and adults were exposed to sewage effluents that had undergone treatment processes (A1-A7) at Hammarby Sjostad’s sewage treatment plant in order to evaluate the effectiveness of the treatment processes.
