ABSTRACT
Results of studying of the factors influencing level of pollution of three small rivers are given in the work, located in the various physiographic regions of the Republic of Tatarstan. The list of the priority substances polluting river waters is established. By means of formalized generalized an indicator (an index of impurity of waters) it is shown that, despite essential reduction of outputs, qualities of river waters during 1982 - 2002 years remained at a low level with prevalence to the fourth class of the quality, corresponding the polluted waters. Cyclic nature of change of quality pollution of waters that is explained by influence of the meteorological sizes, the general for theregion (air temperature and quantity of an atmospheric precipitation) learned. The received results allow to draw a conclusion on an important role of the meteorological sizes in the course of formation of quality of river waters which river water and an assessment of permissible anthropogenic load on water ecosystems depending on a hydro meteorological mode of the territory can lay down in a basis of the subsequent development on short-term and long-term ecological forecasting of extent of pollution.

Keywords: pollution, climatic factors, quality of water.
