Dermal and respiratory exposure to ethion was determined for 17 men in eight spray crews in Florida citrus spray operations. Respiratory exposure was less than 1% of the total exposure. Hands represented 42% of the total body exposure for applicators and 76% for suppliers. At one location, suppliers exhibited a larger decrease in ChE activity than applicators. This difference appeared related to the higher mean dermal ethion exposure to suppliers. Acute symptoms of organophosphorous poisoning were not observed. The total percent/hr of the probable human dermal LD50 was very low in all cases. These data indicate a relatively low potential acute hazard to workers applying ethion with air blast equipment under the conditions of this study.
在佛罗里达州柑橘喷洒作业中，对8个喷洒作业组的17名男性进行了乙硫磷皮肤和呼吸道暴露情况测定。呼吸道暴露占总暴露量的比例不到1%。对于施药人员，手部暴露占全身暴露的42%，对于辅助人员则占76%。在一个地点，辅助人员的胆碱酯酶活性下降幅度大于施药人员。这种差异似乎与辅助人员较高的皮肤乙硫磷平均暴露量有关。未观察到有机磷中毒的急性症状。在所有情况下，可能的人体皮肤半数致死剂量的每小时总百分比都非常低。这些数据表明，在本研究条件下，使用鼓风设备施用乙硫磷的工人面临的潜在急性危害相对较低。
