Title Exposure to ultrafine particles in asphalt work
Bibliographic information Dec. 2008, Vol.5, No.12, p.771-779. Illus. 23 ref.
Abstract An earlier study demonstrated that asphalt workers show a loss of lung function and an increase of inflammation biomarkers during the paving season. The aim of this study was to investigate which possible agents cause the inflammatory reaction, with emphasis on ultrafine particles. The workers' exposure to total dust, polycyclic aromatic hydrocarbons, and NO2 was determined by personal sampling. Ultrafine particles were measured by means of particle counters mounted on a van following the paving machine. Findings showed that pavers were exposed to relatively high concentrations of ultrafine particles throughout their working day, with possible adverse health effects.
