It was studied the influence of zinc and iron at concentrations of 50 and 100 µg/L on cell number, chlorophyll a fluorescence, content of photosynthetic pigments and reactive oxygen species, as well as neutral lipids in the raphidophyte algae Heterosigma akashiwo. Zinc has been found to act on physiological and biochemical processes without affecting the population dynamics of microalgae. It was revealed the negative effect of iron on the fluorescence of chlorophyll a, number of photosynthetic pigments, reactive oxygen species and neutral lipids. The most toxic metal for H. akashiwo turned out to be iron. It was shown that the concentrations of the studied metals do not contribute to the development of H. akashiwo “blooms”.
