This study was conducted to study the genotoxicity potential of soil contaminated by the fly ash emitted from coal fired thermal power. The metals/metalloids (Fe, Zn, Pb, Cd, Mo, Cu, Cr, Co and Ni) concentration of contaminated soil (prepared by mixing equal proportion of soil and fly ash, w/w) was estimated with the help of atomic absorption spectrophotometer (AAS) model: AA 7000, SHIMADZU before plantation of Tradescantia pallida in pots. Trad-MCN was performed as per standard protocol given by Ma. The image of MCN (micronuclei) was taken with the help of Leica (DM200). It was observed that the presence of metals/metalloids in contaminated soil caused the formation of micronuclei in Tradescantia pallida by chromosomal breakage. Present study showed that fly ash contaminated soil can be genotoxic and it can be biomonitored using Trad-MCN bioassay.
