Statistical Modelling of the Determinants of Historical Exposure to Bitumen and Polycyclic Aromatic Hydrocarbons Among Paving Workers

摘要

Introduction: An industrial hygiene database has been constructed for the exposure assessment in a study of cancer risk among asphalt workers. Aim: To create models of bitumen and polycyclic aromatic hydrocarbons (PAH) exposure Intensity among paving workers. Methods; Individual exposure measurements from pavers (N = 1581) were collected from 8 Countries. Correlation patterns between exposure measures were examined and factors affecting Exposure were identified using statistical modelling. Results: Inhalable dust appeared to be a good proxy of bitumen fume exposure. Bitumen Fume and vapour levels were not correlated. Benzo (a) pyerene level appeared to be a good Indicator of PAH exposure.
