WHAT ARE THE RISKS OF NANOTECHNOLOGY WORKERS?
The risks with nanotechnologies are not yet fully described, they are relatively new and are still under study.
The main route of exposure for workers is the respiratory and dermatological routes. When nanoparticles enter the body through the respiratory tract, they are normally deposited in the lungs, but they can also be present in the nasal mucosa, mouth, pharynx, larynx, trachea, bronchi, bronchioles, and alveoli.
These nanoparticles can enter the skin through the hair follicles, thanks to their small size, however these risks are still under study and not much is known about the subject. The risk of entry of nanoparticles through the digestive tract is also recognized, these are associated with carelessness and poor practice by workers, food intake in prohibited areas.
All these exposures can lead to multiple negative health conditions, such as liver damage, cellular genotoxicity, DNA and RNA damage, which makes it potentially carcinogenic, cardiovascular risks, reproductive damage, and the presence of pulmonary mesothelioma is associated.
It is important to carry out periodic monitoring of exposed personnel, as well as to create awareness in workers of the risk to which they are exposed and the proper use of personal protection elements.
