摘要：

The paper gives results of tests in a controlled environment test room to measure211u001econcentrtons of 2-butoxyethanol and particles during application of a cleaner to 211u001erealistic surfaces (counter tops, glass, walls). 2-Butoxyethanol was collected on 211u001eTenax and analyzed by gas chromatography. Concentrations of droplets were measued 211u001econtinuously with an aerodynamic particle sizer. During two sets with the cleaner 211u001ediluted 1 part with 9 parts water, the average concentrations of 2-butoxy-ethanol 211u001eduring the 20-minute cleaning period were 13.5 and 10.3 mg/cu m, about half the 211u001eNIOSH recommended exposure limit of 24 mg/cu m. After 2 hours, the concentrations 211u001edropped below 4 mg/cu m in the room exhausted at a rate of 1 air change per hour.
