Water is the most important resource in the world and its pollution is on the rise globally affecting both human and environmental health [1]. Currently, tens of thousands of substances are known to contaminate water and organic chemical stressors play an important role in this group [2–6].

Currently, tens of thousands of substances are known to contaminate water and organic chemical stressors play an important role in this group [2–6]. Their residues have been detected in many environmental matrices including surface water, groundwater, wastewater, and sludge. Therefore, it is essential to provide an effective method able to detect the contaminants in aquatic systems. Total Organic Carbon (TOC) is an aggregate measurement used to indicate the amount of organic contamination from natural (NOM) and non-natural sources (provided as a sum parameter) [7–9]. With the development of a SEC DOC Detector coupled with an HPLC Size Exclusion Chromatography (SEC) system, a separation and quantification of aromatic and nonaromatic organic fractions as a function of molecular weight is possible [10–15]. The combined HPLC SEC UV + DOC system provides a better understanding of all organics present as opposed to only those that have a chromophore or fluorophore [16]. The resulting information can be correlated to size fractions of specific contaminants or functional groups. The following article presents results from using TOC-SEC to characterize water quality» weiterlesen» einklappen
