Original Abstract
Fragments of plastics (microplastics) are currently considered as contaminants harmful for various environmental compartments and biota. In soil, their analysis is hampered by soil matrix complexity and certain chemical and physical similarities between some plastics and soil organic matter. For this reason, the methods for identification are time consuming and laborious due to the need to separate the microplastics from soil matrix, and therefore, approaches for direct microplastics analysis are of importance. Recently, we have reported several approaches for direct analysis of microplastics in soils including analysis of gases evolved from thermally degraded plastics (evolved gas analysis) [1] and comparison of mass losses obtained by thermo-oxidative degradation (thermogravimetry, TG) [2]. The latter includes two approaches, the first one uses non-contaminated soil, while its TG record is subtracted from the TG record of soil containing microplastics. In the second approach, the uncontaminated soil is replaced by a combination of equations, which reflect the mutual relationship between various soil compartments derived from natural soils and represent a soil universal model. In this work, we describe the development and validation of the TG approaches for detection of a wide range of microplastics including PET, PE, PVC, PS and PHB. In particular, we show the development and testing of all possible scenarios and discuss the weaknesses and positives of the developed approaches.
