Comparison of concentrations in the breathing zone

Abstract

dc:description.abstract

The concentrations in the "breathing zone" were analyzed on three human subjects in simulating work conditions. The experiments were carried out in a wind tunnel having 40&feet; x 12&feet; x 9&feet; dimensions. Ethanol vapor mixed with nitrogen was used as a tracer gas. Samples were taken at the forehead, adjacent to the nose (nose), the mouth, neck, chest, right lapel, left lapel. Nose was sampled at l liter per minute (lpm) and 0.15 lpm at different times, while the others were sampled at 0.15 lpm at two different wind tunnel velocities. The source was released at naval height for each subject.;It was concluded that wind tunnel velocities, and ratios of the chest and the shoulder dimensions played a significant role in the concentration among the sampling sites. Sampling rate affected only the concentration at the nose and at no other sampling site. Further studies would be useful in determining the impact of wind tunnel velocities and the selection of human subjects with a variety of anthropometrical dimensions and clothing use.
