Comparison of the effects of biodegradable and conventional polyester-based microplastics on soil abiotic processes

Popis výsledku v původním jazyce

The properties, occurrence, and adverse effects of conventional microplastics are examined worldwide. However only few studies have focused on biodegradable microplastics (micro-bioplastics), whose abundance in environment is expected to grow continuously [1]. After the entrance to soil, the micro-bioplastics may interact with parts of soil organic matter (SOM) via weak interactions and induce the structural changes in SOM. This affects primarily the properties of SOM and secondarily also the properties of SOM water, which alters soil ecosystem functions [2]. In this study, selected abiotic soil indicators were determined for soil contaminated with polyhydroxybutyrate (PHB) microbioplastics and PET microplastics to evaluate their effect on soil. Peat was used as a model of soil organic matter. Water holding capacity of SOM, strength of water binding (evaporation enthalpy of soil water), water molecule bridges stability (demonstrated as a steep increase in heat capacity, WaMB) and content of soil aliph
