Outline of Final Research Achievements |
Existence of sulfur containing compounds as ligands for essential trace metals (Fe, Cu) was investigated. Existence of ligands which form highly stable complexes with copper was assured by pseudopolarography for all sampled waters including Lake Biwa (freshwater lake) and Lake Shinji (brackish lake). Determination of sulfur containing compounds in suspended fraction of the samples of Lake Biwa showed the concentration of cysteine in the order of some micromole per liter and that of glutathione in the order of some hundreds nanomole per liter. In the concentration of these two compounds in the samples of Lake Shinji, the order was reversed. From this result, detection of these compounds in dissolved fraction of lake water was expected.
