Description:
A handwipe sampling and analysis procedure was developed for the measurement of dermal contract to pesticides. his procedure utilizes cellulose dressing sponges wetted with 2-propanol. wo-step wiping procedure is described that ensures that the entire hand is sampled. emoval efficiency experiments show that dry residues of the pesticides chlorpyrifos and pyrethrin I are quantitatively removed from hands immediately following contact. esults suggest that the procedure may remove pesticide residues that are deeply embedded in the skin and not removed by soap-and-water washing. xtraction efficiency studies for 29 other pesticides show that the proposed extraction method may be applicable for a wide range of pesticides including phenoxy-acid herbicides. ield testing of the procedure indicates that it is easily implemented by sampling personnel and readily accepted by children.
