[Determination of ratios of acid pollutant washout in the center of Spain].
Samples were simultaneously taken of precipitation and atmospheric aerosol in two (rural and urban) stations, during 1986 and 1987, in which sulphates, nitrates and chlorides were analyzed by ionic chromatography. The wet deposition of the S and N composites were greater in the urban than in the rural area, and opposite was true for the chlorides. Regarding the aerosols, the average biennial concentrations of the anions studied were greater urban than in the rural area. Based on the figures obtained for the precipitation and the atmospheric aerosols, the washout ratios of each anion and the non-marine sulphates were determined. Both stations that the sulphates as a whole and the non-marine sulphates had very similar washout ratios while those of nitrates were greater in the rural area. The potential regressions between the rates at which they were washed away and the volume of precipitations reveal excellent correlation coefficients.
