【 摘 要 】

An air quality evaluation of indoor environmentswith focus on lower carbonyls was carried out in 50 public places using TO-11Amethodology. Formaldehyde levels (ranging from 12.5 to 1034 mg m-3)were above the threshold limit in 49 of 50 analyzed samples while acetaldehyde(ranging from 5.2 to 840 mg m-3) and acetone (ranging from 5.5 to4839 mg m-3) were respectively bellow the limits of OSHA and NIOSHin all samples. However all samples were bellow the threshold limits suggestedby the Brazilian legislation – NR-15. A correlation study between thecarbonyls and temperature and humidity was also done.
