The aim of this study was, survey of lead in the five copy centers of Tehran. Materials and methods: Five copy centers were chosen as the object of characterization of lead. All samples were taken during working hours, Non- working hours and ambient air. Concentrations of Pb were determined by inductively coupled plasma (ICP). Samples have been analyzed statistically using Excel. Results: During Working hours, fine particulate matters and lead will be increased. Lead concentration in working hours was 10 to 20 times greater than ambient air. Conclusions: The concentration of lead depended on the number of printing devices and ventilation rate. https://japh.tums.ac.ir/index.php/japh/article/view/120 https://japh.tums.ac.ir/index.php/japh/article/download/120/58
