CYTOGENETIC AFTER-EFFECTS OF MUTAGEN SOIL CONTEMINATION WITH EMISSIONS OF BURSHTYNSKA TPS

Abstract

A cytogenetic analysis of the root meristem cells of winter wheat rootlets, which were affected by soil contaminants of Burshtynska TPS and ash-disposal area № 1, was made. An increase of chromosome aberrations was recorded: 1.5-2.5 and 1.8-3.0, respectively. Their highest frequency was observed when soil mutagen effect occurred in 3- and 5-km zone and an ash-disposal area. The spectrum of chromosome alterations is mostly presented by singular and double fragments and dicentric bridges. An increased mutation level, found in the vicinity of Burshtynska TPS, proves the fact of possible negative genetic consequences of the effect of emissions from stationary sources of heat power engineering on organisms, and it requires further monitoring of the areas adjacent to thermal power stations of Ukraine.
