Clastogenicity of lanthanides — induction of micronuclei in root tips of Vicia faba

Abstract

The clastogenic property of two lanthanides, Praseodymium and Neodymium, was evaluated by scoring the frequencies of micronucleated cells in the interphase and chromosome/chromatid aberrations at ana-telophases in root tips of Vicia faba L. The significant increase in the frequency of micronucleated cells coupled with the increase in the frequency of chromosome/chromatid bridges and lagging chromosomes/chromatids suggest that these two are clastogenic for Vicia faba root cells.
