Abstract

This work shows the more relevant issue related to the first chemical characterization of natural organic matter of the Pasto River. Modern instrumental analysis techniques such as Thermochemolysis-GC-MS, Field Flow Fractionation Chromatography, and Inductively Coupled Plasma Mass Spectrometry (ICP-MS) were necessary. The results showed that the main composition of this matter were organic compounds such as carboxylic acids, aromatic compounds with a molecular mass around 5 kDa. The presence of iron and chromium ions are signs of a possible contribution of pyrite-rich volcanic soils of the area and some effluent discharged without control of the small artisanal leather industry, respectively.
