Even though synthetic nanoparticles pose potential environmental risk, their impact on the environment is still not well understood. TiO2 nanoparticles are among the most used and widespread nanoparticles, therefore, the contamination of the environment with these nanoparticles is inevitable. One of the properties, due to which are these nanoparticles used, is their photocatalytic effect upon UV irradiation. During this process, especially in the presence of water, highly reactive radicals are formed. They have an oxidative effect on organic compounds, this effect is largely used for the photodegradation of organic pollutants. Therefore, it can be hypothesized that the contamination of soil by TiO2 can lead to the degradation of soil organic matter. On the contrary, some authors suggested that TiO2 polymerization reactions between soil organic matter (SOM) moieties. Thus, the aim of this work is to clarify which processes occur after irradiating soil contaminated with TiO2 nanoparticles. To assess the impact of TiO2 nanoparticles and UV/vis irradiation on SOM, we caried out experiments during which soil contaminated with TiO2 nanoparticles was irradiated at different water contents. These samples were then analyzed using thermogravimetry and FTIR spectrometry. Surprisingly, using thermogravimetry, it was possible to observe effects of irradiation on soil biomass and also ecotoxic effect of TiO2 nanoparticles. However, no changes caused by photocatalytic activity of TiO2 nanoparticles were detectable using thermogravimetry. Data acquired using FTIR spectrometry were processed using two different statistical methods – correlation analysis and principal components analysis. Correlation analysis was found t to be not a suitable method of data evaluation for the purpose of this work. Principal components analysis proved, that higher and caused its degradation.
