The influence of lead on dynamics of lipid peroxidation and activity of superoxide dismutase in shoots of aquatic moss Fontinalis antipyretica Hedw. was investigated. It was fixed activation of lipid peroxidation on the initial stages of lead stress. 30- and 60-minute expositions with heavy metal induced increasing of superoxide dismutase activity. The quantitative changes in the electrophoretic spectrum of SOD under lead influence were revealed.
