Personal exposure of workers to atmospheric PAHs on gasworks sites--The SOLEX study.
The aim of the SOLEX study was to estimate the personal exposure of workers to atmospheric polycyclic aromatic hydrocarbons (PAHs) on former gasworks sites in the Paris metropolitan area. Devices to sample gas and particulate phases for 9 PAHs were carried during one working day of a study week in November 1997 by 24 workers and in June 1998 by 19 workers with contrasted job profiles involving different opportunities for contact with the soil; among these volunteers, some were active in the process of contaminated soil remediation during the November study period. PAH concentrations were measured by high-performance liquid chromatography. Subjects working on the site under remediation were clearly more exposed (684.1 ng/m3 for total PAHs in November 1997) than workers, without close contact with soil, whose PAH exposure was similar to that measured by fixed monitors in the ambient air in Paris. The contrasts were weaker in June 1998, when soil remediation had nearly been completed. Only subjects involved in activities with close contact with the ground were found with exposures exceeding background levels. Further investigations are needed to improve our understanding of the influence of the pollutants present in the soil.
