Abstract:Sulfur dioxide (SO 2) is a ubiquitous air pollutant, present in low concentrations in the urban air, and in higher concentrations in the working environments. Consequently, it has become important to study the toxic effects of SO 2 in the environment to humans. Vicia faba have been used for evaluating chromosomal aberrations since the early 1920s. In the present study, the Vicia root-micronucleus assays was selected to assess for DNA aberrations induced by sulfur dioxide. The V.faba test was essential ca...
