There are a few data of toxic concentrations and their distribution of cigarrete and Shisha smoking in Café. Therefore, the aim of this study is to know the concentration and the distribution of both CO and CO2 gases in Rojhelat Café in Duhok city. Both gases have been measured in different positions of Café before opening and until closing the place. Furthermore, the distributions of gases at different places and different elevation have been measured. The results showed that the effect of shisha on producing gases is more than cigarrete. We found that the toxic gases in Café were too high. This study will help the Café manufacture how to design the building such Café for air conveyor and condition.
