ABSTRACT
The advent of a new genre of services and consumer products across many fields is only one way in which nanotechnology has altered the face of the world. The usage of materials with dimension aspects in the nano-range has prompted concerns about worker, consumer, and environmental safety despite their distinct benefits and vast range of uses in the home and industrial sectors. Nanoparticles can affect people and the environment via interactions through a variety of processes because of their tiny size and other new physiochemical properties. Additionally, the features of nanoparticles that determine their toxicity are explored, as well as potential methods by which nanoparticles can enter the human body. There is an urgent requirement to introduce the methodologies that can evaluate the lethal effect of nanoparticles on humans as well as the environment because there is very little information available pertaining to long-term vulnerability to humans. Additionally, methods for reducing human exposure to harmful nanoparticles, including hazard identification and risk assessment, successes, shortcomings, and upcoming difficulties of toxicological investigations including nanoparticles are also discussed in this chapter.
