采用了一种定性估计任务水平暴露的方法，并在五个小型工厂进行了实际测量验证。结果表明，职业卫生师一般是最成功的估计。工厂主管和工人处理估算方法不太成功，因为更多的错误分类的任务。总的来说，该方法将任务分为四类，从无接触到高接触。暴露种类与平均浓度呈正相关，但暴露分布存在重叠。当一个暴露类别中的暴露水平存在相对较大的个体间差异时，这导致了对个别工人暴露的错误分类。结果表明，该方法可用于工作场所暴露分区，但对流行病学目的的估计的有用性并不明确，并且在很大程度上取决于工作场所内的实际暴露特征。定性暴露估计方法与通过测量评估暴露水平相结合，可以重新安排任务或个别工人，并可提高该方法在流行病学方面的有效性。
A method for qualitative estimation of the exposure at task level was used and validated with actual measurements in five small factories. The results showed that occupational hygienists were in general the most successful estimators. Plant supervisors and workers handled the estimation method less successfully because of more misclassification of the tasks. The method resulted, in general, in a classification of tasks in four exposure categories ranging from no exposure to high exposure. The exposure categories correlated positively with mean concentrations, but showed overlapping exposure distributions. This resulted in misclassification of the exposure for individual workers when a relatively large interindividual variability in exposure levels within an exposure category was present. The results show that this method can be used for workplace exposure zoning, but that the usefulness of the estimates for epidemiological purposes is not clear-cut and depends strongly on the actual exposure characteristics within a workplace. A combination of the qualitative exposure estimation method together with assessment of the exposure levels by measurements makes a rearrangement of tasks or individual workers possible and could improve the validity of this method for epidemiological purposes.
