Idoor Air Quality with Particular Reference to Carbon Monoxide in the Room - A Pilot Study

Abstract

Cigarette smoking are the most important reasons for increased carbon monoxide (CO) level in exhaled air. During the experiment, the CO level in indoor air in room was measured. Outdoor air quality data including atmospheric CO concentration, obtained from the own measured and data from the weather platform “freemeteo”. The measurements were carried out with the following variants: outside air, a room ventilated without people, nonsmokers, smokers and non-smoking people, smokers entering the room after smoking cigarettes, smokers who smoke in the room. As proven by measurements, carbon monoxide carried in the lungs by smokers has low concentrations and should not threaten the health of non-smoking users of rooms. The maximum concentration of carbon monoxide in the room was 1.4 ppm. In the external air, the average concentration of carbon monoxide was exactly as much as reported in the literature - 0.3 ppm.
