英文摘要	For the first time, using the example of the Vecherny Oasis (Thala Hills, Enderby Land), data on the content of microplastic particles (<5 mm) in the soils of East Antarctica were obtained. Seven samples taken from a depth of 0-15 cm were analyzed. Two soil fractions (<1 mm and 1-5 mm) were studied in triplicate (42 individual samples). The method for isolating microplastic particles included soil sieving, density separation in a zinc chloride solution, centrifugation, vacuum filtration, and microscopic analysis. For filtration, glass fiber filters with pore diameter of 1.6 mu m were used. Quantification of microplastic particles was carried out using a microscope, digital camera, and appropriate software. Microplastic particles were present in all the analyzed samples. Their quantity varied from 66 to 1933 particles/kg dry soil. In most cases, particles <1 mm predominated (70-100% of all particles). The share of fibers reached 70%; the share of fragments, 30%; plastic films were found sporadically. There was no definite allocation of the increased number of microplastic particles to particular infrastructure facilities, which may be a consequence of the influence of other factors, including local and long-distance transfer of microplastics.
