| Resumen en inglés | Wet (n = 21) and dry (n = 23) deposition samples were collected from March to September 2002 at the southern coast of Ilha Grande. Rainwater pH varied from 4.3 to 6.3 and ionic concentrations (in µmol L-1) decreased in the order Cl- > Na+ > Mg2+ > SO42- > NO3- ~ NH4+ > K+ ~ H+ > Ca2+. Scavenging of sea-salt aerosols was the major source of Cl-, Na+, Mg2+, and Ca2+. Half of total SO42- was non-sea-salt SO42-. Total deposition fluxes of NH4+, NO3-, and non-sea-salt SO42- were respectively 9.3, 17.8, and 16.0 mol ha-1 month-1 |
