||Predicting changes in PM exposure over time at U.S. trucking terminals using structural equation modeling techniques
||July 2009, Vol.6, No.7, p.396-403. Illus. 23 ref.
||This study analyzes the temporal variability of occupational and environmental exposures to fine particulate matter in the U.S. trucking sector, and tests the predictive ability of a novel multilayer statistical approach to occupational exposure evaluation using structural equation modelling (SEM) techniques. For these purposes, elemental carbon mass in PM<1Ám at six U.S. trucking terminals were measured observing concentrations in various locations of the facility. Findings are discussed. Once accounting for systematic prediction errors in background concentrations, the SEM approach provided a strong fit with measured work-related exposures in this occupational setting.
