Nanomaterials exposure to human

Human exposure to engineered nanomaterials (ENMs) is growing rapidly but their effects on human health are still largely unknown. In the last decade, we have witnessed a tremendous increase in the use of nanoparticles and nanomaterials in several areas of human life such as food, cosmetic, medicine, and agriculture. However, this rise in use increases the laboratory synthesis and industrial production of ENMs and is the cause of potential exposure of humans to ENMs. It is expected that human exposure to ENMs will continue to increase in the near future. So, the potential human health effects need to be evaluated. Therefore there is a need for better tools to evaluate the safety of ENMs. The purpose of this chapter is to present the current scenarios regarding the potential routes of human exposure to ENMs and their subsequent health effects. The chapter mainly focuses on the different release mechanisms of ENMs in human environment, their possible routes of exposure and health effects associated with their exposure to humans.
