Изучена динамика процессов фото- и биотрансформации коллоидного железа. Показано, что механизмы этих изменений различны: при инсоляции снижение содержания железа в коллоидной фракции происходит за счет образования более крупных малорастворимых частиц гидроксида Fe (&gt;0,22 мкм), а в присутствии биоты часть железа переходит во фракцию меньшего размера (&lt;1,4 нм).</p></abstract><trans-abstract xml:lang="en"><p>In the work the influence of biota and irradiation on the stability of iron colloids in mire waters is studied. The dynamics of the processes of photo- and biotransformation of colloidal iron has been studied. It is shown that the mechanisms of these changes are different: during insolation, the decrease in the iron content in the colloidal fraction occurs due to the formation of larger poorly soluble hydroxide particles (&gt;0.22 μm), and in the presence of biota, a part of iron passes into a fraction of a smaller size (&lt;1.4 nm).</p></trans-abstract><kwd-group xml:lang="ru"><kwd>коллоиды</kwd><kwd>гидроксид железа</kwd><kwd>растворенное органическое вещество</kwd><kwd>болотные воды</kwd><kwd>облучение</kwd><kwd>биота</kwd></kwd-group><kwd-group xml:lang="en"><kwd>colloids</kwd><kwd>iron hydroxide</kwd><kwd>dissolved organic matter</kwd><kwd>mire water</kwd><kwd>radiation</kwd><kwd>biota</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Исследования выполнены за  счет средств Российского научного фонда, проект   № 21-77-10028.</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Алекин О.А.
