The research on the effect of sulfur oxides (SO2), nitrogen oxides (NxOy) and phosphorus oxides (P2O5) on carbon dioxide (CO2) uptake dynamics of chlorophyll synthesizing microalgae was conducted. The analytic dependences of microalgae growth rates under their СО2 uptake, SO2, NxOy and P2O5 concentrations were obtained. Mathematical models enabling to predict the maximum values of SO2, NxOy and P2O5 oxides concentrations without inhibiting the CO2 uptake dynamics of chlorophyll synthesizing microalgae were built based on the obtained experimental research results.
