Description
Exposure simulation studies are a useful approach for measuring exposures in a controlled setting. They can be designed to evaluate exposures from isolated tasks, examine historical exposures, assess prospective exposures from process changes, or address regulatory requirements such as those under TSCA. While simulation studies can yield valuable information about exposure levels, several important considerations must be addressed to ensure the collected data are accurate and relevant.
This session will provide an overview of what a simulation study is, applications for simulation studies, and practical information on conducting a simulation study including goal-setting, sample collection and analysis, controls and safety, and interpretation of results. Sampling strategies will be discussed including task-based versus full-shift sampling, real-time versus media-based collection, personal versus area sampling, ventilation conditions, prescribed tasks versus typical work practices, and agent-specific concerns such as take-home exposures for particulates. Advantages, limitations and challenges of simulation studies will be discussed in the context of potential study goals. Several completed simulation studies will be utilized as case studies to illustrate concepts covered in this session. These examples will address both dermal and inhalation exposures and will feature a range of agents, including benzene, toluene, ethylbenzene, and xylene (BTEX), asbestos, and lead.
