Original Abstract

Nowadays, the problems with microplastics, i.e. small plastic particles contaminating the environment, is a subject of heated discussions. The literature data suggest that the microplastics from conventional plastics are not as inert as anticipated, but instead, they impact all environmental compartments including soils. In particular, many studies describe negative effects of microplastics on soil fauna and flora. However, the effects on soil abiotic properties and soil quality have not been sufficiently addressed. In this work we present results from the short- and medium-term experiments. We studied the effects that have microplastics from polyethylene terephthalate (PET) and from car tyres on properties of water and soil organic matter in three different soils including chernozem, cambisol and phaeozem. We analysed changes in soil organic matter thermal properties, soil respiration, amount of water and soil aggregation over the period of 15 months to observe their transformation and effects on soil properties. The results revealed that the effect of microplastics on soil properties are soil-type and microplastic-type dependent. Also, it was confirmed that the microplastics were not inert but influenced all the measured parameters. Probably the most important observation was the effect of microplastics on soil organic matter stability. The contamination influenced the soil microbiological activity, which led to the decomposition of soil organic matter and loss of organic carbon. In addition, contaminated soils appeared to have an adverse effect on water holding capacity. Therefore, the microplastics based on non-biodegradable polymers influence significantly the soil ecosystem functions.
