Air sampling was performed using activated charcoal and with the using the health and safety of the United States methods. Using gas chromatography with mass spectrometry and flame detector operation was performed to determine the amount of pollutants. The processing and analysis of data، spss version 13 software was used.

In all parts of the ward، operating room، emergency room، laboratory pollutants benzene، toluene، ethyl benzene and xylene have been identified and followed. The concentration of toluene in waste elimination، landry and pathology parts is 0/5477 mg/m3،0/4052mg/m3 and 0/81 mg/m3 Respectively.

This study shows that pollution exists in all parts of the hospital that is compatible with other studies and This shows the importance of detailed field studies to identify the sources of these pollutants in the environment is sterile، like a hospital.
