Health Hazards of Nanoparticles and Environmental Pollutants
Abstract: The exponential growth in the use of nanoparticles and the prevalence of environmental pollutants have raised significant concerns regarding their health hazards. Nanoparticles, owing to their unique physicochemical properties—such as small size, high surface areatovolume ratio, and chemical reactivity—can penetrate biological barriers, including the bloodbrain barrier, and interact at the cellular and molecular levels. This can lead to oxidative stress, inflammation, and cellular dysfunction, ultimately resulting in potential toxicity. Similarly, …
