Allium test genotoxicity data on water from river valley of Irtysh, West Siberia.

Assessment of genotoxicity of aquatic ecosystems is of great importance for environmental management and assessment of water ecological quality as well as health safety. Data on the genotoxicity of water in rivers of such a large region as Siberia are almost absent. Researchers do not pay enough attention to river floodplains, but such studies are important for assessing the ecological condition of the river system, because a significant part of toxic and genotoxic substances accumulates in the river floodplains A unique feature of the Ob-Irtysh interfluve is its vast floodplain, the largest in the Northern Hemisphere, providing key ecological functions of the territory.
