工人将百草枯施用于番茄和柑橘田，将百草枯施用于含有水葫芦和水蛭的水道，通过在十个身体部位分别贴上真皮α-纤维素垫和个人空气监测仪来监测暴露情况。施番茄者的估计总暴露量明显受拖拉机类型的影响。暴露水平从最高到最低为：开放式拖拉机>封闭式驾驶室拖拉机或高间隙拖拉机。柑橘施药者对百草枯的平均暴露量分别为28.5 mg/hr和12.2 mg/hr，罐浓度分别为0.11%和0.07%。Diquat涂抹器的暴露最小。在所有实验中，呼吸暴露均<0.1%。除了一个例外，所有工人定期收集的尿液样本都没有检测到农药污染。使用一次性工作服和定期清洗的防渗手套可以有效地减少接触。
Exposure of workers applying paraquat to fields of tomatoes and citrus, and diquat to waterways containing water hyacinths and hydrilla, was monitored with dermal α-cellulose pads attached at each of ten body locations and with personal air monitors. Estimated total body exposure for tomato applicators was apparently influenced by tractor type. Exposure levels from highest to lowest were: open tractor > enclosed cab tractor ⩾ high-clearance tractor. Citrus applicators' exposure to paraquat averaged 28.5 mg/hr and 12.2 mg/hr, with tank concentrations of 0.11% and 0.07%, respectively. Diquat applicators received minimal exposure. Respiratory exposure was <0.1% of the total body exposure in all experiments. Urine samples collected periodically for all workers were, with one exception, without detectable pesticide contamination. Use of disposable coveralls and regularly washed impermeable gloves should effectively reduce exposure.
