Evaluation of phytotoxicity and genotoxicity of nitrobenzene with a battery of Vicia faba assay system

0
Nitrobenzene (NB) is an important organic compound intermediate that is widely used in industry. In this present study, to evaluate the phytotoxicity and genotoxicity of NB on plants, Vicia faba was exposed to increasing concentrations of NB (5, 10, 25, 50, and 100 mg L−1). The data revealed that germination rate and radicle length of V. faba seedlings were promoted by low NB concentrations and short exposure periods, while these parameters were inhibited at greater NB concentrations and longer exposures. NB showed dose‐dependent genotoxicity at 0–50 mg L−1 when assessed by mitotic index, micronucleus and chromosomal aberration assays. Environ. Toxicol. Chem. © 2013 SETAC
