An evaluation of the Potential Dermal Exposure of workers to endosulfan and procymidone at the mix/load and application stages was done in small floricultural production units in Argentina. Seven experiments were performed with different operators under typical greenhouse conditions, based on the whole body dosimetry methodology. These results indicate that the mean Potential Dermal Exposure of the application step was 45.0 ± 55.0 mL h(-1) with the highest proportion on torso, head, arms and hands. When the mix/load and application stages were compared, the first was found to contribute the most to the total exposure. Also, the Margin of Safety for the different operations was calculated, and a pesticide surrogate was developed and used to make comparative evaluations of hand exposure for different groups of operators. These results emphasize the importance of the mix/load stage in the exposure process.
在阿根廷的小型花卉生产单位中，对工人在混合/装载和施药阶段接触硫丹和吡丙醚的潜在皮肤暴露进行了评估。根据全身剂量测定方法，在典型的温室条件下，对不同操作人员进行了七项实验。这些结果表明，施药步骤的平均潜在皮肤暴露量为 45.0±55.0mL h(-1)，躯干、头部、手臂和手部的暴露比例最高。当比较混合/装载和施药阶段时，发现前者对总暴露的贡献最大。此外，还计算了不同操作的安全边际，并开发了一种农药替代物，用于对不同操作人员群体的手部暴露进行比较评估。这些结果强调了混合/装载阶段在暴露过程中的重要性。
