摘要：The present study was conducted in GGV campus, Bilaspur in which heavy metals/metalloids speciation of soil (for Cr, Fe, Ni, Cd and Pb) was performed for assessing the genotoxicity of these metals. The metals concentrations were measured with the help of AAS 7000 (Shimadzu) and the standard solution was prepared using standard metal solution of Inorganic Ventures. The concentrations of Cr, Fe, Ni, Cd and Pb (in μg/100 g soil) were 12.4, 33.9, 3.1, 0.07 and 2.4 respectively. The flowers of Tradescantia pallida plants growing in this soil were taken and their micronucleus (Trad-MCN) bioassay was performed. Trad-MCN bioassay was performed using the protocols established by Ma (1981). The study revealed that at these concentrations of metals micronuclei (stained objects that were smaller than the nuclei and not connected to the nuclei are classified as MCN) were formed. Therefore it can be inferred from the present study that soil of GGV campus is genotoxic for the Tradescantia pallida.
