At Berkeley, California, main ionic constituents of bulk precipitation during the wet season of 1974–1975 were SO42-, Cl, HCO3, Na+, and Ca2+, and mean H+ concentration was 10.7 ± 1.5 µeq/liter (pH 5.0). Although SO42- comprised 50% of the anions in bulk precipitation, H+ concentration had the highest correlation with NO3. Impacted air pollutants accumulated on tree leaves between major rainstorms. Atmospheric N and S were correlated with NO3 and SO42- in bulk precipitation and leafwash in a Eucalyptus globulus forest. Ionic composition of bulk precipitation resembled that of surface-soil solution in an adjoining, recently clear-cut area.
