Abstract

The aim of the study was to determine Dissolved Organic Carbon (DOC) and
Biodegradable Dissolved Organic Carbon (BDOC) concentrations, as well as the
correlation between them, in the river water of the Strug basin located in the
Carpathian Foothills. The Strug river's hydrographic basin was chosen for the
study as it is a typical catchment area, which allows ease of measurement. DOC
concentrations in the streams (tributaries) and the Strug ranged from 2.71 to
4.88 mgC/dm3 and from 3.62 to 4.19 mgC/dm3, respectively. BDOC
concentrations in the streams and the Strug ranged from 0.40 to 1.09 mgC/dm3
and from 0.64 to 0.77 mgC/dm3, respectively. BDOC, expressed as the percentage of DOC (%BDOC) ranged from 14.76 to 24.78% in the streams, and from 17.68 to 20.11% in the Strug. The procentage of BDOC is independent of DOC concentrations. The season of the year and the size of the watercourse had the greatest impact on DOC and BDOC concentrations.
