Abstract:Work is devoted assessing the impact of complexation of metal ions with humic substances of natural waters on the distribution of metals into molds. Applied to published data on the values of the conditional stability constants of complexes to describe theactivity of the metal in the environment. The different approaches to the estimation of complexing ability of metal ions in natural waters, the degree of toxicity and migratory activity. The features of the chemical composition of water and foreststeppe zones of the northern taiga and predict the impact of these characteristics on the distribution of metals into molds. The results ofcalculations based on the flow of competitive reactions due to the presence in the system of various cations and anions for the water area of the northern taiga and forest Tyumen region. Shows that the results are important for determining the toxicity ofwater pollution in their metal ions, and can make adjustments to the water quality standards (WQS) with the process of inactivation of metals humic substances waters.
