            <abstract>
                <p>The problem of microsized particle pollution of freshwater features, in particular, lakes, is becoming global, but comparative studies of water bodies, differing in geographical location, hydrological regime and anthropogenic load, remain sporadic. The study analyzed the pollution of the surface water column of the transboundary Lake Khanka (Far East) and Lake Ilmen (North-West). The results obtained show that with the apparent similarity of sources of microparticles, the spatial distribution and their qualitative composition is determined by local hydrodynamic conditions, morphometric parameters of lakes and the nature of nature management. These indicators should be considered when developing strategies for monitoring and assessing the potential risk of exposure of lake ecosystems to micro-pollution.</p>

                <p>Проблема микроразмерного загрязнения пресноводных объектов, в частности, озер, приобретает глобальный характер, однако сравнительные исследования водоемов, различающихся по географическому положению, гидрологическому режиму и антропогенной нагрузке, остаются единичными. Проведен анализ загрязнения поверхностной толщи вод трансграничного озера Ханка (Дальний Восток) и озера Ильмень (Северо-Запад). Отмечено, что при кажущемся сходстве источников поступления микрочастиц пространственное распространение и их качественный состав определяется локальными гидродинамическими условиями, морфометрическими параметрами озер и характером природопользования. Данные показатели следует учитывать при разработке стратегий мониторинга и оценки потенциального риска воздействия микроразмерного загрязнения на озерные экосистемы.</p>
