Abstract
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 µm 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.
期刊介绍：
Eurasian Soil Science publishes original research papers on global and regional studies discussing both theoretical and experimental problems of genesis, geography, physics, chemistry, biology, fertility, management, conservation, and remediation of soils. Special sections are devoted to current news in the life of the International and Russian soil science societies and to the history of soil sciences.
Since 2000, the journal Agricultural Chemistry, the English version of the journal of the Russian Academy of Sciences Agrokhimiya, has been merged into the journal Eurasian Soil Science and is no longer published as a separate title.
