The subway transport method is come more popular in the last years and in some cities has become the primary public transportation mode. Many people are using the underground transport system because it is an efficient and fast. However, one environmental disadvantage of any underground transport system is that it operates in a confined space that may permit dust accumulation. The passenger typically spend only 30–40 min in metros, the air pollutants emitted from various interior components of metro system as well as air pollutants carried by ventilation supply air are significant sources of harmful air pollutants that could lead to unhealthy human exposure. This article presented the actual situation of the air quality from the subway transport system from Bucharest. An investigation was conducted among for underground subway stations to the examination of practical operation conditions of their cooling units. The overall field testing included information such as air conditioning system formation, equipment types and system.
