Worker exposure to airborne particulates was stimulated in a laboratory under controlled conditions. Small volumes, 3.8 L (1 gal.), of finely divided powders were transferred at 1-min intervals to 23-L (6-gal.) containers over 30-min time intervals. A high-volume filter array in the exit vent of the specially designed exposure laboratory was used both to(More)
A simulation computer program is described for the quantification of particulate emissions generated by wind erosion of coal surfaces. Erosion potentials reported by Cowherd provide the basic test data correlating suspended particulate loss with wind speed. Daily fastest miles of wind, precipitation and surface disturbances are stochastically simulated.(More)
