Приведены впервые полученные для пресноводных водоемов Восточной Антарктиды данные о содержании в воде частиц микропластика (на примере оазиса Холмы Тала, Земля Эндерби). Исследования выполнены во время 15-й Белорусской антарктической экспедиции в 2022/2023 гг. с отбором и фильтрацией воды из трех озер и одного временного водоема. Фильтрация осуществлялась в два этапа: в полевых условиях через планктонную сеть для концентрирования пробы и затем в лаборатории через фильтры типа «Белая лента». Высушенные фильтры после доставки в Минск проанализированы с помощью микроскопа, цифровой камеры и соответствующего программного обеспечения. Установлено, что частицы микропластика присутствуют во всех проанализированных пробах: доминируют волокна, на долю которых приходится 81 % общего количества частиц микропластика. Размер частиц, представленных фрагментами неправильной формы пластмасс, в 90 % случаев составляет менее 1 мм. Размер волокон в 91 % случаев находится в диапазоне от 1 до 5 мм с максимальным значением 16,4 мм. Показана важность развития исследований и оценки уровней микропластикового загрязнения водоемов Антарктики с учетом сезонных изменений их состояния, морфометрических и других особенностей.

The first data on the content of microplastic particles in freshwater reservoirs of the East Antarctica (by the example of the Thala Hills Oasis, Enderby Land) are presented. The studies were made during the 14th BAE in 2022/2023 with the selection and filtration of water from three lakes and one temporary reservoir. Filtration was carried out in two stages: in the field conditions through a plankton network to concentrate a sample and then in the laboratory through White Ribbon filters. Dried filters after delivery to Minsk were analyzed using a microscope, digital camera and consulting software. It was found that microplastic particles were present in all analyzed samples. Fibers dominated in all samples, amounting to 81 % of the total microplastic particles. The particle size, represented by fragments of irregularly shaped plastics, is less than 1 mm in 90 % of cases. The fiber size in 91 % of cases ranges from 1 to 5 mm with a maximum value of 16.4 mm. The importance of developing research and assessing the levels of microplastic pollution in Antarctic fresh water is shown with the consideration of seasonal changes in their condition, morphometric and other features.
