Indoor air pollution due to integrated garages

The paper presented did some research on the indoor air pollution due to integrated garages. For that purpose the health offices Bremen and Bremen-North investigated organic substances like benzene, toluene and xylene in 47 selected flats. The measuring was done using passive sampling tubes over a period of two weeks. The analysis was carried out in an external laboratory by gas chromatography. The results indicate that - dependent on the positions and the dimensions of the garages - indoor air pollution with organic chemicals exists in adjacent flats at known level. In isolated cases a remarkable decline of the quality of the indoor air was measured mainly due to the construction of the buildings. Because of the unhealthy carcinogenic potential of benzene preventive precautions for the environmental health are required. There is no generally indoor air pollution due to integrated garages. But in case of a complaint the health offices should check the particular situation. For new constructions adequate ventilation should be a must.
