Reactive Oxygen Species (ROS), Nanoparticles, and Endoplasmic Reticulum (ER) Stress-Induced Cell Death Mechanisms presents the role of ROS‒mediated pathways cellular signaling stress, endoplasmic reticulum (ER) stress, oxidative stress, oxidative damage, nanomaterials, and the mechanisms by which metalloids and nanoparticles induce their toxic effects. The book covers the ecotoxicology of environmental heavy metal ions and free radicals on macromolecules cells organisms, heavy metals‒induced cell responses, oxidative stress, the source of oxidants, and the roles of ROS, oxidative stress and oxidative damage mechanisms. It also examines the nanotoxicity, cytotoxicity and genotoxicity mechanisms of nanomaterials and the effects of nanoparticle interactions.
