    Abstract

    Data are presented from a field investigation of the extent of penetration of Guthion wettable powder (azinphos-methyl) through work clothing (regular and Tyvek spray suits) and three protective garments (Saranex-laminated Tyvek, Gore-Tex, and an experimental composite structure) during the typical mixing and spraying activities of fruit orchardists in central and northern Utah. Exterior and interior azinphos-methyl levels were collected using α-cellulose pads and were used by quantify exterior exposure patterns and percent protection afforded by each garment type. No relationship between inside azinphos-methyl pad levels and outside azinphos-methyl loading (µg/cm2 of patch), ambient temperature, relative humidity, or wind speed was evident for any of the garments tested based on results of correlation analyses.
