Printer is widely used in our daily life, and the emitted particulate matters especially nanoparticlesraised great concerns. It has been demonstrated that nanoparticles can cross the blood-air barrier when ente-ring the lung by inhalation, which has the possibility to induce oxidative damage, inflammatory reaction andgenotoxicity in the body. Exposure level of emitted particles and associated toxicological effects were thefoundation of health risk assessment of this kind of photocopying equipment. In this paper, we thoroughly re- viewed the progress of field monitoring of the printer emission ...
