Engineered Nanomaterials

Abstract

Engineered nanomaterials (ENMs) are intentionally designed materials of ≤100 nm such as titanium dioxide nanoparticles, cerium oxide nanoparticles, iron oxide nanoparticles, silver or gold nanoparticles, carbon family nanomaterials (graphene, quantum dots, nanohorns, nanotubes, fullerene/buckyballs), transitional metal dichalcogenide nanoparticles, or silica nanoparticles. These have entered our lives through industrial and consumer products, or workplace exposure. As learned industrial professionals, we can deal with this influx through a better understanding of ENMs themselves, and their underlying potential toxicity. In spite of ever‐changing rules due to an improved understanding of the toxicological and environmental impact of ENMs, it is also extremely important to understand current EU and U.S. regulations with regard to workplace exposure limits as well as how to better measure and manage the health risks. In this updated chapter, we cover the various types of ENMs, potential health effects such as cardiovascular, pulmonary, skin, gut, and immune toxicity, exposure assessment, and occupational risk management.
