Implications of a gradient in acid and ion deposition across the northern Great Lakes states.

Abstract

Average precipitation pH, 1979-1982, declines from west to east from 5.3 to 4.3 along a cross section of sites in Minnesota, Wisconsin, and Michigan. This answers questions about the seasonal and geographic pattern of anthropogenic acid precursor emissions and reaction products (S042-, NO<, H+, NH4+) that increase from west to east. Except for higher… (More)
