Experimental results of the number of particles covering the 0.10–0.12, 0.12–0.15, 0.15–0.20, 0.20–0.25, 0.25–0.35 and 0.35–0.45 μm ranges are presented. Using spectral analysis as a statistical technique, two 12 h and 24 h significant peaks are obtained for each size range. In order to interpret the meaning of both peaks, the hourly particle size, traffic and nitrogen oxide patterns are compared. The contribution of domestic heating, traffic exhaust emissions and the strong influence of the gas-to-particle conversion processes mainly within the 0.10–0.15 μm range, may be inferred.||URI:||http://hdl.handle.net/10553/47322||ISSN:||0390-5551||DOI:||10.1007/BF02561453||Source:||Il Nuovo Cimento C [ISSN 0390-5551], v. 18, p. 1-8|
