Gaseous oxygen dissolved in surface water is required for the survival of the organisms living in it; decomposers critical to recycling of biogeochemical materials in the ecosystem, or fish species preferred for human consumption. If the material has been adapted instead of reproduced from the original RSC publication La titration volumétriqrie par le thiosulfate de sodium est remplacée par une titration potentiométrique. Lajos Winkler (May 21, 1863 – April 14, 1939) was a Hungarian analytical chemist. The regular Winkler proce dure should be used in deter mining the dissolved oxygen content of pure waters. contained in this article in third party publications
