“…The results of this laboratory study indicated that Gore-Tex fabric, which has been shown to be an effective barrier to the pesticides Guthion, parathion, paraquat, and dinoseb [2,8], offered similar thermal comfort as clothing worn by independent growers. Further research is needed to determine the barrier effectiveness of Gore-Tex fabric to a wilder range of pesticides, formulations, and concentration levels.…”

“…Tyvek and Gore-Tex had previously been shown to have excellent resistance to pesticide penetration ; chambray was selected as the third fabric despite its poor resistance to pesticide penetration [2,8], since it is frequently worn by growers during pesticide application. Tyvek is a disposable polyethylene-coated 100% spun-bonded olefin fabric.…”

“…A movement analysis was completed to insure that the prototypes would accommodate the movement needs of the growers and incorporate safety features related to working around farm machinery. Fabric penetration studies [2,8] were also conducted to evaluate the effectiveness of test fabrics as barriers to selected pesticides.…”

In an effort to develop protective clothing that offered improved heat dissipation characteristics to pesticide applicators, the thermal responses were collected from 54 male subjects wearing two prototypes and a typical clothing ensemble. The performance of three designs and three fabrics with known chemical protective characteristics was determined in a controlled laboratory, simulating a hot environment. Analysis of physiological and perceptual data revealed that one protective fabric offered a similar thermal comfort level as chambray, a fabric growers often wear for pesticide application, which is an ineffective barrier to pesticide penetration.

Because many pesticide handlers persist in wearing and reusing conventional workclothes, a renewable functional finish that enhances the pesticide-protective qualities of fabrics would be useful. This study investigated the ability of starch to act as a pesticide trap, preventing transfer and increasing removal by laundering, and the effect of carboxymethyl cellulose on release of pesticide in laundry. The retention and distribution of methyl parathion (MeP) on 65% polyester/35% cotton fabric was studied with four finishes: starch and carboxymethyl cellulose (CMC) as nondurable finishes; durable press resin (DP) and durable press/carboxymethyl cellulose (DP/CMC) as durable finishes. Starching with an add-on of 8% (w/w) effectively reduced the area of contamination and enhanced the removal of methyl parathion from polyester/cotton fabrics. Residual pesticide values for CMC, DP, and DP/CMC finishes were similar to that of the unfinished fabric. While distribution profiles of methyl parathion throughout the yarn and fiber structures were similar for all the finishes, lower concentrations of pesticide were observed on the cotton fibers from the starched fabric. Starch reduced the pesticide transferring by rubbing from both 100% cotton and 65% polyester/cotton fabrics. These studies support the intriguing theory that starch can act as a pesticide trap on the fabric surface to decrease pesticide transfer and to enhance pesticide removal. Extensive penetration studies, field studies, and additional investigation of fiber, yarn, and fabric parameters are needed to further quantify the effects of starch.

This research investigated the potential for contamination of fabric by aldicarb (Temik 15) pesticide. Fabric soiled with synthetic perspiration or synthetic sebum was contaminated with Temik granules for various time periods and extracted with methanol. Extracts were analyzed with high performance liquid chromatography. The aldicarb transferred to both soiled and unsoiled fabric; however, the sebum soil and longer contact time increased the transfer of aldicarb to fabric. The dissipation of aldicarb from fabric was affected by the soil type and the formulation of the Temik granule. It is apparent a potential for dermal exposure to granular pesticide exists when the pesticide is trapped in pockets or folds of clothing.
