Penetration of soil dust through woven and nonwoven fabrics.
Several types of fabrics were laboratory-tested for their effectiveness in workers protection to pesticide-laden dust encountered in the agricultural environment. Of the applied less than 100 mesh dust, penetrations through knitted jersey and woven fabrics were greater than 87% and less than 5.8%, respectively. Treatment of woven fabrics with fluorocarbon polymers curtailed penetration by greater than 60%. Nonwoven fabrics allowed less than 0.5% dust penetration. Parathion mixed with 100-mesh sieved dust resulted in increasing "ppm" levels with decreasing particle size; extent of parathion conversion to paraoxon was independent of particle size for the sandy loam dust used.
