This study was done to assess the \r\napplicability of the HPSEC-UV-fluorescence (High Performance Size Exclusion \r\nChromatography with UV and fluorescence detection) method to illustrate the \r\nvariable nature of NOM among catchments. Water samples from two different \r\ncatchments in Southern Finland were analyzed. The land use of the catchments was \r\ninvestigated by using Corine land cover (CLC) data from the years 2006-2018.

In \r\nTuuruj\u00e4rvi and Joutsij\u00e4rvi catchment, DOC concentrations (dissolved organic \r\ncarbon) in surface waters were 1.3-3.8 times higher than in GBV catchment.
