【 摘 要 】

The rapid expansion of nanotechnology is outpacing health and safety recommendations for engineered nanomaterials. Thus, there is a lack of information about the effects that nanomaterials can induce in the human health. Nevertheless, workers in nanotechnology-related industries are potentially at risk of being exposed to nanomaterials. Therefore, there is a need of characterize the behaviour of personal protective equipment against penetration nanoparticles, in order to provide an adequate protection to the workers. In this study, the efficiency of several protective dermal equipment against water-based NaCl aerosol was evaluated. For this purpose, different protective clothing and gloves were selected to carry out the assays, simulating typical use conditions of protective equipment under occupational settings. Results obtained exposed that the level of protection offered by the distinct types of personal protective coveralls depended not only on the fabric, but also on their fitting to the body of the subject. On the other hand, the efficiency of the protective gloves was set in the range from 95% to 99%, depending on the thickness and the type of material.
