摘要

Abstract

This paper reports data on the dissolved and colloidal organic carbon in the Zhujiang (Pearl) River estuary. DOC concentration was 142 to 239 μmol/L in the freshwater taken in March 1997 from the four Zhujiang River tributaries flowing into the Lingdingyang estuary. High concentration was observed in the Humen tributary located near Guangzhou. The rapidly increased DOC concentration at low salinities (∼5) may be attributed to the exchange between macroparticulate and dissolved organic matter during the early stage of estuarine mixing. DOC concentration overall followed the mixing line until salinity 25

where the Deep Bay is located and where DOC was elevated. This elevated DOC may suggest a local organic matter source from Shenzhen. Using a cross-flow ultrafiltration (CFF) system equipped with a Millipore Prep-scale CFF 1 kD regenerated cellulose membrane

we also separated the colloidal organic matter from the truly dissolved fraction (<1 kD). CFF membranes were carefully evaluated for their applicability (retention characteristics

blank level and mass balance) to separate colloidal organic matter. COC in the study area ranged from 5 to 85 μmol/L

representing 3%–32% of DOC. The highest COC percentage was found at low salinities (<5) in both winter and summer. Evidence suggests in-situ production of colloidal material at this salinity range. Beyond this point

a very modest removal was observable until high salinities. Again

an increase in COC concentration was shown in the samples taken from the Deep Bay.
