Abstract: | Abstract Several types of fabrics were laboratory‐tested for their effectiveness in worker protection to pesticide‐laden dust encountered in the agricultural environment. Of the applied <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. |
