The cytogenetic monitoring of the higher aquatic plants of the Chernobyl accident exclusive zone was carried out. Analyze was carried out by the anaphase express-method on apical cells of the root meristems tissues of the plants, which are the dominant or subdominant at literal coenosis of air-aquatic plants within the water-bodies Chernobyl Accident Exclusive Zone. The highest level of cytogenetic damages in apical cells of the plants from left-bank flood plain of the Pripyat River – the most radioactive contaminated water-bodies of Ukrainian part of Chernobyl accident exclusive zone – was registered. The distribution of the different aberration types in cells of plants from left-bank dammed flood plain of the Pripyat River points to practically equivalent effects of radiation and chemical factors.
