Environment, Health and Safety Issues of Nanotechnology

The National Institute for Occupational Safety and Health has conducted initial research on how nanoparticles interact with the body’s systems and how workers might be exposed to nano-sized particles in the manufacturing or industrial use of nanomaterials. NIOSH currently offers interim guidelines for working with nanomaterial’s consistent with the best scientific knowledge. Nanotechnology events are been conducted all over USA by most of the universities and associations on 29th of March. At The National Personal Protective Technology Laboratory of NIOSH, studies investigating the filter penetration of nanoparticles on NIOSH-certified and EU marked respirators, as well as non-certified dust masks have been conducted. These studies found that the most penetrating particle size range was between 30 and 100 nanometers, and leak size was the largest factor in the number of nanoparticles found inside the respirators of the test dummies. The market research on health is the main issue.
