Nanotoxicology: Emerging Discipline from Ultrafine Particles

This lecture explores nanotoxicology as a growing field originating from studies on ultrafine particles, focusing on the deposition, translocation, and effects of nanoparticles in the human body. It delves into the mechanisms of particle clearance, dissolution, and distribution in different regions of the respiratory system. The presentation also covers the emission, transformation, and impact of various compounds in Earth's atmosphere, emphasizing the role of oxidants, biogenic and anthropogenic sources, and their effects on ecosystems. Additionally, it discusses the concept of acid deposition, its mechanisms, impacts on aquatic and terrestrial environments, and the role of different chemical reactions in atmospheric processes.
