The lead absorbed by the roots induce oxidative stress conditions through the Reactive oxygen species (ROS) production for the pea plants cultivated hydroponically for 96 h on a Hoagland medium with the addition of 0.1 and 0.5 mM of Pb(NO3)2. The alterations in $$ {\text{O}}_{2}^{ - \cdot } $$ and H2O2 concentrations were monitored spectrophotometrically which show a rapid increase in $$ {\text{O}}_{2}^{ - \cdot } $$ production during the initial 2 h, and in case of H2O2, during the eighth hour… CONTINUE READING
