Title Worker exposure to a herbicide applied with ground sprayers in the United Kingdom
Bibliographic information Feb. 1987, Vol.48, No.2, p.167-175. Illus. 8 ref.
Abstract This study was designed to measure potential dermal and respiratory exposure during the application of 2,4-dichlorophenoxy acetic acid, with 5 types of application equipment commonly used in the United Kingdom. Potential dermal exposure was higher during mixing and loading all tractor-powered sprayers than during spraying. Potential dermal exposure from tractor-powered sprayers fitted with conventional hydraulic nozzles was lower than from knapsack sprayers, with exposure from a tractor-powered sprayer fitted with controlled-droplet application equipment intermediate in this regard. There was no difference in potential dermal exposure between tractor-mounted and tractor-drawn sprayers fitted with conventional hydraulic nozzles. The hands were the most highly exposed part of the body during mixing and loading operations for all sprayers, and during spraying with tractor-powered sprayers. The lower legs of the workers were exposed principally when knapsack sprayers were used. For all 5 sprayers, potential respiratory exposure, where detectable at all, was negligible compared with potential dermal exposure.
