| Abstract |
The authors examined the effects of H2SO4 and HNO3 on dissolved organic carbon (DOC), pH, and DOC fractions in extracts from Spodosol O and B horizon samples of a forest soil from eastern Maine. The DOC in O horizon extracts decreased with increasing acidity. For the B horizon extracts, DOC increased with increasing acidity. For the B horizon, similar trends were observed, although hydrophobic/hydrophilic acid ratios were lower, indicating that hydrophobic acids have a lower solubility with increasing acidity. From an environmental perspective, increasing acidic inputs through wet and dry deposition on forest Spodosols of New England may have significant consequences in the solubilization and transport of metals and acidity because of differences in DOC fractions.
