Progress in new technologies brings with it unknown dangers and risks. The biggest development of the last few years is the use and production of fine and ultrafine particles (aerodynamic diameter less than 2.5 ?m), which, according to new studies, may have a negative impact on human health. It is very important to deal with this problem, especially from the point of view of workers who are at the front line of contact with these new materials, and it means that they are also at the greatest risk.
