Zusammenfassung: | <jats:title>Abstract</jats:title><jats:p>A close correlation exists between dissolved organic carbon (DOC) concentration and UV absorbance at 254 nm (A<jats:sub>254</jats:sub>) in natural waters. DOC and A<jats:sub>254</jats:sub> were measured for soil solutions, throughfall, stemflow, and surface waters collected from a forested site located in eastern Austria. The slopes of lines determined by linear regression of DOC versus UV absorbance were very similar to those determined for wet deposition and throughfall samples collected in Nordrhein‐Westfalen, Germany by <jats:italic>Bartels</jats:italic> (1988). The intercept of the regression line in the current study indicates that approximately 1 mg L<jats:sup>1</jats:sup> of non‐UV‐absorbing DOC is present; it is suggested that this is due to saturated aliphatic compounds such as acetate or formate.</jats:p> |
