Entomoremediation is defined as the use of insects in the processes of removal of pollutants from contaminated biomass or soil. The investigations undertaken as part of the task are focused on assessment of the possibility to use larvae of Hermetia illucens (common name: black soldier fly or black fly) to remove heavy metals from sediments. The larvae are reared in one of the IA PAS laboratories.


Concurrently, emission and absorption of methane by soil and biocarbon are being investigated. Methane, i.e. one of the greenhouse gases with a 28-fold higher global warming potential than that of carbon dioxide, plays an important role in nature. While the industrial sources of emission of methane have been relatively well identified and described, the phenomenon of absorption/generation of this gas in soils has not been fully recognised, especially in terms of the impact of factors on the emission and absorption in soils, which can be both methane emitters and sinks depending on the air and water conditions.
