Dr. Bob Krieger’s pioneering work to advance utilization of human biomonitoring data to better understand and communicate pesticide exposures was one of the inspirations that led us to develop Biomonitoring Equivalents. Biomonitoring Equivalents (BEs) are defined as the concentration of an analyte in human urine or blood that is equivalent to an external health risk assessment guidance value such as a point of departure or Reference Dose. BEs are used to interpret human biomonitoring data in a risk assessment context by means of the margin of exposure (MOE), where MOE = BE/[biomarker concentration]. This presentation will highlight the evolution of BEs and their application for risk-based interpretation and communication of human biomonitoring results from such sources as CDC’s NHANES, the Canadian Health Measures Survey and California’s Environmental Biomonitoring Program.
