The article presents the results of treatment of the culture of green microalgae Chlorella vulgaris Beijer. with iron ions Fe2+ and Fe3+. The data analysis was carried out using a graphical method of probit analysis. It was shown that Fe3+ is more toxic for chlorella culture compared to Fe2+. It was established that both ionic forms of iron are non-specific toxicants, since the range of their effect is quite wide.
