Fiber Exposure During Use of Baby Powders.

PB81225989

Publication Date	1972
Personal Author	Dement, J. M.; Shuler, P. J.; Zumwalde, R. D.
Page Count	20
Abstract	Exposure to asbestos (1332214) fibers and free silica (7631869) during the use of baby talcum powders was investigated. Bulk and airborne samples of nine commercial powders were examined using standard fiber count methods. Seven powders were fibrous. These were subjected to a simulated exposure test in which a doll was diapered while air was collected 10 inches from its breathing zone and that of the diapering individual. Dusting was continued for 5 or 15 seconds. A 3 minute sampling procedure was used to obtain total time average airborne concentration measurements. Fourteen dusting tests were conducted. Fifteen second dustings resulted in fibrous exposure with all tested powders, while 5 second dustings did not produce fibrous exposure with three powders. Based on an estimated 10 to 15 diaper changes per day, a cumulative exposure of 30 to 45 minutes per day was estimated. Exposure to fibers was greatest during the first 20 seconds of use and diminished rapidly. Fiber concentrations ranged between 0 to 18 fibers greater than 5 microns in length per milliliter during this time. Free silica ranged from 0.05 to 2.03 percent by weight.
