Abstract

Background: Chemical reactions and flames used in the laboratories are the main sources of nitrogen oxide production. However because of high toxicity of NITROGEN OXIDES, it was decided to determine the extent of NOx pollution in the work place atmosphere of the pharmacy laboratories personnel.Material and Methods: The air of five different laboratories was sampled for three days. GRITZ-SALTZMAN METHOD was used for the NOx determination. In this method NO2 was absorbed in an absorbing solution. Nitrogen oxide (NO) was converted to nitrogen dioxide by passing the air through potassium dichromate solution before have been passing into absorbing solution. The nitrogen oxide concentrations of collected samples were determined using calibration equation obtained at maximum wavelength of 550 nm.Results: As it is indicated from the results there were significant differences between NO2 concentrations of all laboratories. No significant differences were observed between their NO concentrations. Total concentration of NITROGEN OXIDES in the Analytical chemistry, central, toxicology, pharmagenosy and hydrology laboratories in the working days are 2.545, 3.55, 2.90, 3.18, and 6.65 ng mL-1, respectively.Conclusion: As the comparison of the results with the value reported by EPA showed atmosphere of no laboratories in the pharmacy school are polluted. These data also indicate relatively good operation qualities of the ventilation systems in the laboratories. So there is no need to be worry about personnel's health concerning NOx pollution.
