Изучено действие меди в концентрациях 10, 25 и 50 мкг/л на рост популяции, содержание фотосинтетических пигментов (хлорофилла а и каротиноидов) и степень повреждения ДНК микроводоросли Heterosigma akashiwo. Показано, что численность клеток не отклонялась от таковой в контроле при всех концентрациях вещества, содержание фотосинтетических пигментов снижалось, а процент повреждения ДНК возрастал с увеличением концентрации металла.

Effects of copper in concentrations 10, 25 and 50 mkg/L on the population growth, content of photosynthetic pigments (chlorophyll-а and carotenoids) and level of the DNA damage of the microalgae Heterosigma akashiwo were analyzed. The number of cells was similar to control in all concentrations of copper, the content of the photosynhetic pigments decreased and the persent of the DNA damages increased along increasing concentration of the pollutant.
