Feb 09, 2021· Allium cepa (A. cepa), the acclaimed ecotoxicological model plant, not only provides the opportunity to study the toxicological effects of environmental pollutants but also can be used to assess the risk of magnification, as it is cultivated widely to be consumed even in raw and unprocessed forms (Boros and Ostafe, 2020).
The Allium cepa test showed genotoxicity in NaClO-treated samples at acid pH and in a ClO2-treated sample at pH 7. PAA-treated samples were always nongenotoxic. Since the concentrations tested of free disinfectants are usually present in drinking water for biocidal purposes, genotoxicity of these compounds could be a public health problem.
