Potential respiratory and dermal exposure to applicators were estimated in a ground boom spray application of 2,4-D and dicamba. Time-weighted averages for airborne herbicide residues did not exceed 2.2 microgram/cu.m. in the cabs of application vehicles allowing only minor respiratory exposure. Dermal exposure was important as relatively large amounts of 2,4-D (1.2 - 18 mg) and dicamba (0.32-6.6 mg) were rinsed from applicators' hands. Urine analysis showed that the maximum elimination of herbicides occurred between 16 and 40 h after terminating exposure. A dicamba isomer (20% of the active material in the commercial formulation) was excreted in higher concentrations than dicamba in applicators' urine suggesting different toxicokinetic properties for the two compounds.
在使用2,4 - D和麦草畏进行地面喷杆喷雾作业时，对施药人员潜在的呼吸道和皮肤暴露情况进行了评估。施药车辆驾驶室内空气中除草剂残留的时间加权平均值不超过2.2微克/立方米，仅会导致轻微的呼吸道暴露。皮肤暴露较为重要，因为施药人员手上冲洗出了相对大量的2,4 - D（1.2 - 18毫克）和麦草畏（0.32 - 6.6毫克）。尿液分析表明，接触终止后16至40小时内除草剂的排泄量最大。施药人员尿液中一种麦草畏异构体（商业配方中活性成分的20%）的排泄浓度高于麦草畏，这表明这两种化合物具有不同的毒代动力学特性。
