We present the data on the level of pollution
of Astrakhan inland waters with zinc, copper, lead, mercury,
nickel, and cadmium. Dynamics of a change in the level of
pollution within five years - from 2004 to 2008 - in different
seasons of the year is given. All the results aimed at determining
the contents of heavy metals are statistically processed.
The obtained data are analyzed; the recommendations for
improvement of an ecological condition of the inland waters
