Simulation of Historic Product Use and Extrapolation of Measurements in Scenarios Not Readily Measurable
Historical formulations of building materials such as caulk and window glazing may have included asbestos as an ingredient. The exposure intensity during installation of products that contained some percentage of asbestos, according to specific work conditions of modern interest, was found to be poorly understood and undocumented in the published literature.
Our scientists developed a study to measure the risk of the application and removal of these products. Using historical manufacturer formula cards, laboratory scale batches of asbestos containing caulks and window glazing were remanufactured and subsequently utilized in an exposure simulation study designed to fill data gaps.
