Peak expiratory flow (PEF) and forced expiratory volume in 1\u2005s (FEV<jats:sub>1<\/jats:sub>) were measured using a pocket electronic meter. Daily levels of air pollutants and meteorological variables were collected at outdoor city monitoring sites.<\/jats:p><jats:p>Significant inverse associations were observed between morning and evening PEF and carbon monoxide level (p\u200a=\u200a0.01\u20130.03), without clear differences between lags (0\u20133\u2005days). An increment of 1\u2005mg\u00b7m<jats:sup>\u22123<\/jats:sup>CO was associated with a PEF variation ranging -2.6\u2013\u2009-2.8%.
