摘要：

The particulate emissions near a large steel plant located in a densely inhabited suburb of the town of Geneva (Italy) have been studied for a period of six months. We hale used two-stage continuous streaker samplers and subsequent PIXE analysis with hourly resolution, to follow both seasonal and daily trends. The first streaker sampler remained installed very close to the plant cokery and furnaces, while another sampler was moved to different locations. Samples have been analysed by PIXE, deducing concentrations for elements from Na to Pb. During part of the campaign. the aerosol fractions with aerodynamic diameter (D-ae) < 2.5 mu m (fine fraction) and with 2.5 < D-ae < 10 mu m (coarse fraction) have been separately collected. We have measured and analysed about 8500 PIXE spectra: the steel plant emissions have been identified to some extent and resolved from other aerosol sources. (C) 1999 Elsevier Science B.V.
