Particles of synthetic polymers in fresh snow in the northwest of the Kola peninsula in 2020–2021
Pollution of the hydrosphere, the atmosphere and the upper lithosphere by synthetic polymers has now become a global human problem.

Summary: | Pollution of the hydrosphere, the atmosphere and the upper lithosphere by synthetic polymers has now become a global human problem. In this connection, a study of newly fallen solid precipitation was carried out from December 2020 to April 2021 in the north-west of the Kola Peninsula to identify polymeric particles that could be absorbed from the atmosphere by snow crystals. Snow sampling was carried out along highways at a distance from roads in calm weather. In the laboratory, melt snow water was filtered through nuclear filters, which were scanned under a binocular MBS-10 microscope to take account of insoluble polymer fibers. Simultaneously, filters stained with a Nile Red solution were analyzed under a Carl Zeiss AxioImager D1epifluorescent microscope for microplastic investigations. Synthetic polymer particles were identified among the aerosol material. The polymeric particle composition was strongly dominated by irregularly shaped polymer micro-fragments. Polymer macrofibres and polymer microfibers were also constantly present. By the research carried out the first assessment of polymeric particles flows to the earth surface with solid precipitation in the north-west of the Kola Peninsula was done. Загрязнение гидросферы, атмосферы и верхней части литосферы синтетическими полимерами признано в настоящее время глобальной проблемой человечества, в рамках решения которой одной из приоритетных задач является выявление путей и масштабов миграции полимерных частиц. В связи с этим с декабря 2020 г. по апрель 2021 г. на северо-западе Кольского полуострова были проведены исследования свежевыпавших твердых атмосферных осадков с целью выявления в них полимерных частиц, которые могли быть абсорбированы из атмосферы кристаллами снега. В талой снеговой воде полимерные частицы идентифицировались под бинокулярным микроскопом МБС-10 и эпифлуоресцентным микроскопом Carl Zeiss AxioImager D1. Данные о потоках полимерных частиц на поверхность земли с твердыми атмосферными осадками на северо-западе Кольского полуострова ... |
