Abstract

The purpose. To determine features of seasonal changes of density of manganese and to analyze the possible causes of its fluctuation in ponds. Methods. Water samples are taken from drawoff Otsechnoye of river Teterev and clear-water basins during 2006-2008. Density of manganese is determined using colorimetric method. Results. In study the problem of overflow of maximum concentration limit (MCL) of manganese in water of drawoff (especially in summer months) is considered and ways of its solution are offered. Conclusions. Revealed in drawoff Otsechnoye of river Teterev in 2006 – 2008 and existing till now overflow of maximum concentration limit of manganese on the background of its significant seasonal fluctuation should be reduced by use of aquatic organisms-concentrators and seizing the receipt in drawoff of the residues of manganous microfertilizers, humus matters, etc.

Key words: manganese, seasonal fluctuation, waters of drawoff, clear-water basins, drinking water, agricultural sources of manganese.
