Resumen:
The spatial, meteorologica1, and seasonal factors associated with precipitation pH in Bahia Blanca and its surroundings are presented. From April 1984 to April 1985, 85 rain events were studied from 12 sites that represent significant land-use sectors of the city. Mean pHfor all sites ranged from 6.5 to 7.2. The area ís characterized by alkaline precipitation since most stations reported maximum values in excess of 7.6. The highest values of pH were observed under the influence of continental air masses, which have traveled over the pampassoil, thus introducing large amounts of alkaline cations. The lowest pH values were obtained during the winter season when marine advection introduces high concentrations of spray. Stations located close to the estuary and the industrial park present the larger effect of sea spraybut also of the incidence of an incipient atmospheric contamination.
