Assessing Levels of CO2, CO, NO2 and SO2 in Indoor Air Using Dräger Sensors: A Case Study of Prishtina, Kosovo

Summary/Abstract: Studies in large cities revealed that indoor air pollution concentrations are at such levels where it can cause serious health impacts. The main source of the release of substances in the environment is the emission of gases (produced during the combustion process) such as carbon dioxide, carbon monoxide, sulphur oxides, nitrogen oxides, ammonia and others. In this study the assessment of indoor air quality in 26 places in Prishtina city were investigated and the main objective of this study was monitoring of the air quality through the determination of gases concentration of C02, C0, N0x and S02. Also the ratio of CO2/CO2+CO was calculated. Concentrations of CO2, CO, SO2 and NOx were determined using “Dräger” instrument, model “X-am 7000 digital gas monitor”. Environmental risk assessment of air quality was done by comparing the obtained results with air WHO standards. During that period were found a permanent presence of some toxic gases in high concentrations in indoor areas. Results show that CO2 levels were ranged 300-4000 ppmv. The concentration of CO was ranged 0.6-17 ppmv and was reported to be under limits value in all locations. Also concentrations of SO2 and NOx (except air sample S6) were reported to be under WHO air limits value. According to gases concentration, many locations show values characteristic for highly and extremely contaminated indoor places.
