All fields of industry are applying nanotechnologies for the development of advanced materials, there¬fore at present the number of workers exposed to nanosized materials are significantly increasing. Unfortunately, protective equipment for nanoparticles (NPs) is of uncertain efficacy so the risk of noxious effects, in particular allergic sensitization, on workers gives many concerns. At the same time, studies of allergic physiopathology demonstrated that the lack of prevention and treatment could result in invalidating dis¬eases that, in case of professional etiology, might imply removal from the job and compensation. Therefore, a deeper knowledge of the role of NPs in inducing allergic diseases is mandatory to implement the risk assessment and preventive measures for nanosafety in the workplace. The possibility that NPs favor, ex¬acerbate or directly induce allergy is being suggested by recent experimental investigations in cellular and animal models. Unfortunately, studies are heterogeneous and few data have received experimental confir¬mation, lacking reproducibility. What comes to attention is the uncertainty about the real plausibility of the observed experimental effects, as there are only a few reported cases of allergy onset or exacerbation for workers exposed to NPs. However, the potential for NPs to induce, favor or exacerbate allergies seems possible even though not completely demonstrated. This should be a greater incentive to carry out appro¬priate epidemiological studies that are lacking and really needed.
