This study was designed to measure potential dermal and respiratory exposure of agricultural workers during the application of a typical herbicide, 2,4-dichlorophenoxy acetic acid, with five types of application equipment commonly used in the United Kingdom. The workers were monitored during filling and loading operations and during spray application. 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 five sprayers, potential respiratory exposure, where detectable at all, was negligible compared with potential dermal exposure.
本研究旨在测量农业工人在使用英国常用的五种类型的施药设备施用典型除草剂2,4-二氯苯氧基乙酸期间潜在的皮肤和呼吸道暴露情况。在填充和装载操作以及喷雾施药过程中对工人进行监测。在混合和装载所有拖拉机驱动的喷雾器期间，潜在皮肤暴露高于喷雾期间。配备传统液压喷嘴的拖拉机驱动喷雾器的潜在皮肤暴露低于背负式喷雾器，配备控制滴液施药设备的拖拉机驱动喷雾器的暴露在这方面处于中间水平。配备传统液压喷嘴的拖拉机悬挂式喷雾器和牵引式喷雾器之间的潜在皮肤暴露没有差异。在所有喷雾器的混合和装载操作期间以及使用拖拉机驱动喷雾器进行喷雾期间，手部是身体暴露程度最高的部位。工人的小腿主要在使用背负式喷雾器时暴露。对于所有五种喷雾器，与潜在皮肤暴露相比，潜在呼吸道暴露（如果可以检测到的话）可忽略不计。
