DSC study on the influence of PET microplastics on abiotic processes in soil

Popis výsledku v původním jazyce

The ecotoxicological and health adverse effects of microplastics are examined worldwide, however only few studies focuses on impact of these particles on abi-otic properties of soil organic matter (SOM) [1]. Disruption of soil physical and chemical structure not only can endanger soil organisms, but it also can lower the agricultural crop yields and landscape water reserves [2]. Selected abiotic soil in-dicators were determined for soil contaminated with PET microplastics to evalu-ate their effect on soil quality. The peat was chosen as a model soil due to the high content of SOM. Prior to the measurement, the peat was wetted and dried under three different relative humidities to assure the conditions variability typi-cal for arid areas. Differential Scanning Calorimetry (DSC) was used to measure evaporation enthalpy of water from soil, stability of water molecule bridges stabil-ity (WaMB) and lipids melting enthalpy. Also, water holding capacity was deter-mined. We have found that PET microplastics
