National inventory of natural organic compounds : an interim report / J. Lawrence.: En36-522/81-1978E-PDF
"A preliminary inventory of 27 rivers and lakes across Canada for natural organic compounds indicates that humic acid, fulvic acid, tannins and lignins account for the major part of soluble organics in surface waters (visually assessed by the brown colour of water). Fulvic acid usually occurs in larger quantities (x10) than humic acid. The chloroform potential (chlorination by-product previously reported on by Oliver and Lawrence) roughly follows the concentration of these two acids. Stable amino acids (proline, alanine and glycine) were found in high concentrations in areas of livestock farming. The amino acids form only a small part of Kjeldahl nitrogen and therefore it must be concluded that the bulk of the nitrogen comes from agricultural fertilizers. Relatively low concentrations of oil, grease and PCBS were recorded from the localities samples"--Executive Summary.
