Variability and dynamics of micronuclei rate in participants of transatlantic march of the VIIth Ukrainian Antarctic expedition

Cytology and Genetics 2004, v 38, number 4, 37-43

The estimation of individual variability and group dynamics of micronuclei rate in buccal cells of participants of transatlantic march of the VIIth Ukrainian Antarctic expedition (Sevastopol – UAS «Akademik Vernadsky» – Sevastopol) was carried out. The general average rate of micronuclei was 2.20 ‰. Individual values of micronuclei frequencies varied in wide limits. The maximum value of CV was 92.4 % and the minimal one was 48.4 %. Individual averages of micronuclei rates varied from 1.70 to 2.78 ‰. Dependence of individual and group dynamics of micronuclei rates on environmental factors (temperature, atmospheric pressure and storm activity) was tested. No significant correlation of these parameters was found.
