Title Determination of handwash removal efficiency: Incomplete removal of the pesticide chlorpyrifos from skin by standard handwash techniques
Bibliographic information May 1994, Vol.55, No.5, p.425-432. Illus. 20 ref.
Abstract To develop standard procedures for evaluating the removal efficiency of handwash techniques, a known amount of the insecticide chlorpyrifos was transferred to volunteers' hands, which were then washed by standard techniques. Time between exposure and washing, the amount of washing solvent and skin loading were measured. Prewashing with ethanol increased removal efficiency; removal efficiency immediately following contact decreased for lower skin loading levels. Substantial amounts of the insecticide were either absorbed or adsorbed through the skin, and pesticide residue levels recovered by standard handwashing techniques did not represent accurate estimates of dermal exposure. Appropriate laboratory-based removal efficiency studies should be conducted prior to field investigations if handwashing is to be used to estimate dermal exposure in the workplace.
