Оценка выполнена на третьи и седьмые сутки эксперимента. Оба элемента в концентрации, превышающей ПДК, снижают численность водоросли. Наибольшее влияние оказало железо. Однако изменения структур клеток при добавлении Fe3+ не наблюдалось. При добавлении Zn2+ выявлена деформация клеток и истечение клеточного содержимого P. foraminosum. Флуоресценция хлоропласта становилась менее интенсивной при воздействии Fe3+. ЗАФ при наличии в среде Zn2+ и Fe3+ увеличивалась.</p></abstract><trans-abstract xml:lang="en"><p>Influence of heavy metals as zinc and iron with concentrations of 50 and 100 mg/L on dynamics of the cells abundance, morphology, fluorescence of chlorophyll a, and green autofluorescence is examined for the microalgae Prorocentrum foraminosum. The impact was measured on the 3rd and 7th days of the experiment. Both elements in concentration above the maximum permissible levels reduce the cells number, with the higher impact for Fe3+. However, Fe3+ caused no changes in structure of cells. The impact of Zn2+ caused the cells deformation and excretion of the cellular content. The chloroplast fluorescence became less intensive under influence of Fe3+, but the green autofluorescence had increased under presence of Zn2+ and Fe3+ in the medium.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>: Prorocentrum foraminosum</kwd><kwd>цинк</kwd><kwd>железо</kwd><kwd>численность клеток</kwd><kwd>флуоресценция хлоропласта</kwd><kwd>зеленая автофлуоресценция динофлагеллят</kwd></kwd-group><kwd-group xml:lang="en"><kwd>: Prorocentrum foraminosum</kwd><kwd>zinc</kwd><kwd>iron</kwd><kwd>cell number</kwd><kwd>chloroplast fluorescence</kwd><kwd>green autofluorescence of dinoflagellates</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Авторы благодарят ресурсный центр «Морской биобанк» Национального научного центра им.
