【摘 要】Abstract：The roots of onion（Allium cepa）stand out for having cells with large size and small number of chromosomes.These characteristics make them useful in bioassays for the measurement of a variety of cytogenetic and morphological parameters，in which they can be used as toxicity indicators of the induction and formation of micronuclei and chromosomal aberrations.Based on this background，the potential genotoxic effect of phenol concentration on cells of A.ceparoots was investigated either in terms of induced aberrations or micronuclei formation.The results demonstrated that the higher the concentration of phenol，the higher the incidence of abnormalities，thus confirming the genotoxicity of this pollutant. 【期刊名称】生态毒理学报 【年(卷),期】2013(008)004 【总页数】7
