A Simple Proposition for Improving Industrial Hygiene Air Sampling Methods

다국어 초록 (Multilingual Abstract)

When conducting an exposure assessment, the primary goal of the industrial hygienist is to fully characterize the worker’s exposure during a work shift to compare it with an occupational exposure limit.
This applies regardless of the duration of the work activity as an activity that is relatively short in duration can still present exposure in excess of the occupational exposure limit even when normalized over an 8-hr shift. This goal, however, is often impeded by the specification of a minimum sample volume in the published sampling method, which may prevent the sample from being collected or submitted for analysis. Removing the specification of minimum sample volume (or adjusting it from a requirement to a recommendation), in contrast, allows for a broader assessment of jobs that consist of short-duration and high-exposure activities and also eliminates the unnecessary practice of running sampling pumps in clean air to collect a specified, minimum volume.
