Processes and pathways of nutrients, selected heavy metal and arsenic removal from surface runoff from the agricultural and urban catchments in floating treatment wetlands

The proposed project assumes examining the pathways and mechanisms for the removal of biogenic compounds (nitrogen and phosphorus), heavy metals (Cu, Cd, Pb) and metalloid (As) by 4 macrophyte species (Phragmites australis Cav., Iris pseudacorus L., Typha latifolia L., and Alisma plantago-aquatica L.) characteristic for the climate of Poland. Research on the cognitive process will be carried out in two stages: microcosm studies, in which macrophytes will be exposed to various doses of nutrients, metals and metalloid to learn the individual properties of plants, and mesocosm studies, in which macrophytes will be randomly distributed on a floating island and the simulated surface runoff will be discharged to the Floating Treatment Wetland reactor in batch. The results of the project will allow to determine the level of phytoextraction of contaminants by plants and assess the degree of removal efficiency, which at the same time allows to assess the effect of pre-treatment. The results of this project will help to answer the following research questions: how much pollution accumulates in underwater and aerial macrophytes, how much pollution is deposited in bottom sediments and what is the microbiological characteristics of the rhizosphere and sediments? Floating Treatment Wetlands belong to the promoted range of "best management practices". In addition, they are an environmentally friendly solution and adapt to the circular economy approach, especially due to the nitrogen and phosphorus circulation in the environment. The research will provide relevant information on the usefulness of four species of macrophytes generally available in Poland arranged on floating ecological islands for pre-treatment of runoff from urban and agricultural areas. Project significance for GUT: purchase of equipment, development of the discipline of Environmental Engineering, Mining and Power Engineering, promotion of the scientific unit at international conferences, publication of research results in JCR journals.
