Abstract
There are the publications about reduction of water treatment effect of natural water in the presence of humic substances on rationed parameters of drinking water quality, including mutagenic chlorinated organic pollutants and toxic metal ions. It takes place at water treatment station in the process of desinfection by chlorination of initial natural water, containing humic substances. We have assumed that secondary pollution of drinking water by toxic metal ions is possible at the expense of decay of these complex compounds on the desinfection stage or complex compounds can decay under influence of acidic medium in a human stomach. First of all we have confirmed the presence of humic substances in chlorinated drinking water. Total contents of humic substances in drinking water made 2,0-10,9 mg/l. We have carried out studies of toxic metal ions exit from complex compounds with model solutions of peat humic substances. The model solutions were assayed by the action of various desinfection agents. After each effect the contents of metal ions in the solution was determined by stripping voltammetry. It is shown that the complex compounds decay and toxic metals ions appear in drinking water. Because the removing humic substances before desinfection stage is necessary.
