Ecophysiologycal and Environmental Toxicologycal Research Group

Leader of the research group: 
Profile of the group: 

- Chemical characterization of aquatic environment (water body, sediment, phyto- and zooplankton, phyto-and zoobenthos, macrophyton, macro invertebrates, fish) with special attention to the exploration of pollution sources and identification and quantification of pollutants (e.g. pharmaceutical residues, microplastics)
- Monitoring of water quality in rivers and lakes complying with the requirement of the EU Water Framework Directives and database building to follow the changes of physical, chemical and biological parameters of Lake of Balaton as well as Duna and Tisza rivers
- Study of biofilm formation in aquatic environment focusing on the colonization of bacteria on different substrata and the role of their metabolites on the colonization of algae
- Effect of climate change on the nutrient turnover harmonizing with the analyses of biological parameters
- Effect of trace element-enriched or even highly contaminated irrigation waters on the plant cultivation through the soil-plant, plant-human nutrient connections
- Identification of infochemicals emitted by macro- and micro organisms into the freshwater environment applying modern analytical techniques
- Characterization of environmental condition of freshwater and revealing the relevance of the general toxicity of xenobiotics based on the ecotoxicological tests and environmental risk assessment
- Study of physiological effects of toxic materials in aquatic macro invertebrates and fish model organisms. Molecular processes accompanying adaptation to anthropogenic pollution in invertebrates and lower vertebrates
