在生产过程中，在处理纳米粉末过程中，以及在处理含有人造纳米材料的最终产品过程中，潜在的纳米物体可能被释放到工作场所的空气中。模拟暴露过程的实验研究显示，释放后会形成更大的团块。在工作场所进行的研究证实了这一假设，然而，由于报告数据的格式不同，数据仍然非常稀少，不容易进行比较。数量、质量和表面积浓度都有报道，但是，目前还无法估计工人接触的可能性。建议今后的工作场所接触研究将根据一种更为统一的分析和报告结果的方法进行。2009爱思唯尔爱尔兰有限公司版权所有。
In potential nano-objects can be released into the workplace air during production, during the handling of nanopowders and during the treatment of end-products that contain manufactured nanomaterials. Experimental studies that could mimic the exposure processes revealed the formation of larger agglomerates after release. Studies conducted in workplaces confirmed this assumption, however, the data are still very scarce and not easily to compare due to differences in the format of reporting the data. Number, mass-, and surface area concentrations are reported, however, currently an estimate of the potential for worker exposure is not possible. It is recommended that future workplace exposure studies will be conducted according to a more harmonized approach for analyzing and reporting of the results. (C) 2009 Elsevier Ireland Ltd.
