Hydrogen behaviour and ion concentrations in precipitation of Europe and the United States
Hydrogen ions in precipitation vary primarily with (SO(4) + NO(3)) concentration. However, the slope of the H:(SO(4) + NO(3)) relation for high concentrations (0.60 and 0.61) is twice that at low concentrations (0.32 and 0.22) in European and US samples respectively. Sulphuric and nitric acid dominate precipitation in the US. Precipitation in Europe, although almost equally acidic, is dominated by NH(4)(+), Ca(2+) and Mg(2+) salts at total ion concentrations 2 and 3 times higher. Ion concentrations in precipitation, other than H, are proportional to their respective emission fluxes.
