Relationship Between pH Value and Electrolyte Composition of Precipitation

摘要

Data are presented spanning 11 years of observation in the German Federal Republic. Electric conductivity and pH values have shown steady variation with time and present a pattern of seasonal fluctuation that coincides with the fossil fuel heating season. Sulfur dioxide is implicated along with nitrogen oxides, ammonium compounds, and other metallic particulates as the cause of this global change in acidity. A radiochemical analysis was developed using Na exp 36 Cl as tracer. (ERA citation 04:024495)
