The occupational risks and health hazards associated with people working in factories and industries that manufacture and use nanomaterials are not very well known. A lot of factors contribute towards this lack of knowledge. Till recently, we did not have instruments that could detect and analyze these nanoparticles in the air. We did not have any clear idea about how these nanoparticles could affect people and their health either. There is a lack of data regarding presence of nanoparticle related health issues in workplaces, as well. All these factors make it extremely tough to study the impact of nanotechnology related health hazards.

Nanotechnology has led to the development of a number of new materials and structures, and the growth is happening rapidly. This has made it extremely difficult for people to find out exactly what the health and environmental repurcussions of the industry are. As far as research has shown, exposure to nanoparticles can be harmful for health. Exposure to nanoparticles may happen if one inhales the particles, through dermal contact, or through ingestion.

Studies have proven that some of these nanoparticles are biologically active, and these might actually penetrate human skin or affect the lungs. Each person is affected in a different way, because they deal with nanoparticles in different ways.  There are a lot of challenges facing studies and researches regarding occupational hazard relating to Nanotechnology. Some of these challenges include finding the right way to detect and measure exposure levels in factories and industries where people work with nanoparticles. The rest of the problem is related to finding ways of containing radiation exposure, and finding ways through which one can reduce exposure in workplaces.
