Worldwide investment in nanotechnology increased from $432 million in 1997 to about $4.1 billion in 2005. [3]: 1–3 Because nanotechnology is a recent development, the health and safety effects of exposures to nanomaterials, and what levels of exposure may be acceptable, is not yet fully understood.

Nanotechnology has the potential to benefits all forms of work from daily life to medicine and biology. Despite these benefits, there are also health risks when it comes to human exposure to the nano material. Studies have shown that dangerous nano-particles can build up in the body after prolonged exposure.
Research from the U.S. National Institute of Occupational Safety and Health (NIOSH) Nanotechnology Research Center (NTRC) show local exhaust ventilation and High Efficiency Particulate Air (HEPA) filtration to be effective mitigation to theoretically filter 99.97% of nanoparticles down to 0.3 microns.

"This is the ideal make (sic) body. You may not like it, but this is what peak performance looks like," the caption says. The tweet spiraled into a meme, and Twitter users started to post their ...
The environmental impact of nanotechnology is the possible effects that the use of nanotechnological materials and devices will have on the environment. [20] As nanotechnology is an emerging field, there is debate regarding to what extent industrial and commercial use of nanomaterials will affect organisms and ecosystems.
Nanomaterials can be both incidental and engineered. Engineered nanomaterials (ENMs) are nanoparticles that are made for use, are defined as materials with dimensions between 1 and 100nm, for example in cosmetics or pharmaceuticals like zinc oxide and TiO 2 as well as microplastics. [1]
