Characterization and acid–base properties of fulvic and humic acids isolated from two horizons of an ombrotrophic peat bog

Peat humic and fulvic acids were isolated from a surface horizon (0–60 cm) and deeper horizon (>60 cm) of an ombrotrophic peat bog located in Galicia (NW Spain) and which constitutes a record of paleoenvironmental contamination. The humic and fulvic acids were characterized and compared using che...
