Therefore, an understanding of the factors affecting concentrations of indoor contaminants in public transport buses is important to study the impact on the passengers and driver. The various factors affecting the pollutant concentrations in an indoor environment are meteorology, indoor pollutant sources, ventilation settings, exhaust fumes, and outdoor pollutant sources. The indoor pollutants studied in this article are particu-late matter, carbon dioxide, carbon monoxide, sulphur dioxide, nitric oxide, and nitrogen dioxide. 收起
