Environmental toxicology

-Development of test models and biomarkers based on fish and amphibians for risk assessment of chemicals with the potential to interfere with reproduction, early development and sexual differentiation. The work is based on the model species great pond snail, zebrafish and Xenopus tropicalis.

-Health monitoring of wild fish with focus on reproductive health. During the last years our focus has been on perch, roach, three-spined stickleback and other species of relatively low commercial value, but very significant from an ecological perspective.

-The impact of industrial and domestic effluents on fish. The focus has been on effectiveness of various sewage treatment processes and various risk scenarios for aquatic life.

-Hazard characterization of persistent pollutants including brominated flame retardants and per- and polyfluorinated alkyl substances by use of the zebrafish and Xenopus models which we have established.

-Health related environmental microbiology; quantification of the effect on a population from the exposure to microorganisms from waste streams from the society and the barrier effects provided by treatment.
