Benzene emission from building and finishing materials.

The results for the determination of benzene air emissions from building and finishing materials are presented. The test chamber was used to ventilate sample materials at controlled air change rate, temperature and relative humidity. Charcoal sample cartridges were used and then CS2 was desorbed to a packed column gas chromatograph for analysis. The test chamber concentrations of benzene for adhesive were observed to diminish with time. Calculated emission rate for materials tested were determined from 0.4 micrograms/m2/h to 4.4 micrograms/m2/h.
