При облучении солнечным светом вод болота и реки происходит трансформация растворенного органического вещества, а именно его разрушение до низкомолекулярных соединений вплоть до минерализации, и одновременная коагуляция соединений &gt;0,22 мкм. В результате изменения степени окисления Fe и его связей с органическим веществом происходит формирование гидроксидов Fe(III). Возникающие гидроксиды могут образовывать крупные, стабилизированные органическими лигандами органоминеральные соединения &gt;0,22 мкм, с которыми могут соосаждаться Mn, Co, Сd.</p></abstract><trans-abstract xml:lang="en"><p>The interaction of organic matter with metal ions plays a key role in the migration of metals in aquatic ecosystems, the formation of natural water quality, toxicity and bioavailability of metals. Sunlight irradiation of swamp and river waters transforms dissolved organic matter, degrading it to low molecular weight compounds up to mineralization and simultaneously coagulating compounds &gt;0.22 μm. As a result of the reduction and subsequent oxidation of Fe, as well as changes in its bond with organic matter, the formation of hydroxides of Fe(III) occurs. These hydroxides can form large, stabilized by organic ligands organo-mineral compounds &gt;0.22 μm, with which Mn, Co, Cd can co-precipitate.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>растворенное органическое вещество</kwd><kwd>металлы</kwd><kwd>природные воды</kwd><kwd>фотохимическое окисление</kwd><kwd>инсоляция</kwd></kwd-group><kwd-group xml:lang="en"><kwd>dissolved organic matter</kwd><kwd>metals</kwd><kwd>natural waters</kwd><kwd>photochemical oxidation</kwd><kwd>irradiation</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Исследование выполнено при финансовой поддержке РФФИ (проект № 20-3590017) и РНФ (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.
