Air Quality and Health Impacts

The mutagenicity of airborne particulate matter from two locations in Oslo has been studied during the months February to April 1978 using the Ames' Salmonella/liver microsome assay. The content of polycyclic aromatic hydrocarbons (PAH) was determined in some samples. The mutagenic activity of cyclohexane extracts using strain TA98 was for most samples not enhanced by the addition of liver microsomes, indicating the presence of mutagens other than PAH which require metabolic activation. Daily variations in the mutagenicity and the PAH concentrations of the samples followed the same pattern as other air pollution parameters like SO2 and soot. However, probably due to different pollution sources the ratios of mutagenicity and PAH values to SO2 and soot values were not equal at the two sampling sites. It was found that the results were greatly influenced by meteorological conditions.
