Abstract

A large discrepancy between concentrations measured by stationary indoor monitors (SIMs) and personal exposure monitors (PEMs) worn by a person has been well documented in the literature. In addition, one major study that documents this discrepancy identifies housework as an activity associated with increased personal exposures to particulate matter (PM). This study investigates the relationship between the PEM and SIM measurements for a typical cleaning activity using real-time measurement devices. An investigator wearing two real- time particle monitors with breathing-level intakes vacuumed a carpet in a test home. Coarse particles (greater than 2.5 u.m) were resuspended by the mechan
