ABSTRACT
This project presents a study of MAQ in toilets located in the Faculty of Civil Engineering building, University of Nigeria, Nsukka (UNN). This study was conducted to determine the level of gas pollutants that exist in the male and female toilets. The important MAQ parameters considered in this study are SO2, NO, and Microbial Air. The measurements were conducted during break hour and taken using air quality monitoring. The result indicated that SO2 exceeded the threshold value and this could have adverse effect on inhalation such as asthmatic. Finally, the existing SO2 was affected by mechanical ventilation mode, while the existing Microbial air was more generated in female toilet.
