The Investigation of TiO2 NPs Effect as a Wastewater Treatment to Mitigate Cd Negative Impact on Bamboo Growth

The recent emerging evidence reveals that titanium dioxide nanoparticles (TiO2 NPs) can be used as a wastewater treatment. This study provides new information about the possible detoxification role of TiO2 NPs treatment in plants under heavy metal stress, with an emphasis on mechanisms involved. Here, we investigated effects one bamboo species (Arundinaria pygmaea L.) vitro Cadmium (Cd) toxicity conditions. A factorial experiment was conducted completely randomized design four replications concentrations Cd (50, 100, 200, and 300 µM) alone combination 100 200 µM two treatments, well control results indicated enhanced enzymatic non-enzymatic antioxidant activities proline accumulation reducing hydrogen peroxide (H2O2), superoxide radical (O2•−), malondialdehyde (MDA) levels, which led to improved photosynthetic parameters eventual increase plant biomass compared Therefore, toxicity, biomass. We concluded treatments through scavenging reactive oxygen (ROS) compounds (H2O2 O2•−), induced by stimulation capacity plant. also protected cell membranes lipoperoxidation toxicity. concentration had most impact
