Johannes Pohl
PhD student at BVF


I am since May 2016 enrolled as a PhD student at the Department of Biomedical Sciences and Veterinary Public Health (BVF), where Leif Norrgren act as my main supervisor. After acquiring a bachelor of science in biology, and a subsequent master of science in environmental toxicology (both at Uppsala University), I began working as a research assistant at BVF. I also performed my master thesis on the topic Thyroid Endocrine Disruption of Propylparaben Assessed Using an Optimized Xenopus tropicalis Metamorphosing Tadpole Exposure System at BVF with Gunnar Carlsson as my supervisor.

The project which I am involved in, Evaluation of advanced treatment of sewage effluent in full scale, is financed by the Swedish Agency for Marine and Water Management. I have, and will continue, working with small fish as models for biological responses of ozonation of effluents. The aim of my project is to evaluate if any positive and/or negative effects in e.g. the embryonal develpopment, reproduction capability and behavior arises when ozone is used to remove pharmaceutical residues in wastewater effluents.
