The objective of this study was to develop protective clothing for lawn-care specialists and to test the effectiveness of the clothing as a barrier to pesticides in comparison with the regular company uniform. Six volunteers, three wearing the experimental protective clothing and three the company uniform, sprayed a field dilution of Dursban 4E while carrying out regular work activities on each of two test days. Volunteers served as their own controls, wearing a different clothing treatment on the two days. Protective clothing consisted of a cotton/polyester, long-sleeve knit shirt with woven yoke overlay and work pants lined with a microporous film laminate in the lower legs and abdominal area. Urinary excretion of the metabolite 3,5,6-TCP, standardized on the basis of creatinine concentration, measured pesticide absorption. Data indicated that the protective clothing significantly reduced the amount of pesticide absorbed relative to the regular uniform.
