Considering the increasing need of human society for health care and also the expansion of various medical facilities in health care centers there is an urgent need to determine the adverse effects of subsequent medical wastes. In this study we aimed to perform a qualitative and quantitative analysis of medical wastes of Shariati Hospital (Public Hospital) in Tehran. We analyzed weighing of the medical wastes to determine the participation of each hospital section in total hazardous medical wastes generation, then the components of common and infectious medical wastes were analyzed. The raw data were analyzed using Excel and R software. The total amount of generated medical wastes including common, infectious, sharp, and chemical / pharmaceutical wastes in the hospital were 1950/521, 982.78 ± 27.08, 885.76 ± 26.11, 376.06 ± 1.55, and 45.33 ± 3.2 kg/day, respectively and the average amount of wastes generation in each ward of hospital per day was between 1.47-6.86 kg /bed/kg. Also, we considered the production of medical wastes in detail and found that the production of medical wastes was for common wastes 0.11-3.11, infectious wastes 0.77-78.7, sharp wastes 0.03-0.23, chemical/ pharmaceutical wastes 0.01-0.91 Kg/patient/day. The average amount of wastes produced in the hospital was consistent with the World Health Organization's (WHO) report on the amount of daily wastes generation in academic hospitals (4.1-1.8-4 kg/bed/day), but the overall amount of infectious and sharp wastes in subjected hospital was 47.37% which is exceeded the recommended amount by the WHO (15-25%).
