L'influence du vent et de la temperature sur les concentrations en Pb dans l'air urbain I. Cas d'un site situe sous l'influence directe du trafic intense

Abstract A simple mathematical relationship has been established between the Pb concentrations in the ambient air in the vicinity of a heavily trafficked road and some meteorological parameters (wind speed and direction, temperature). The application of this relationship permits the interpretation of the variations in concentrations with respect to the time of day and period of the year.
