ISO 21427-2:2006 is an international standard that specifies a method for evaluating the genotoxicity of water and wastewater using a mammalian in vitro test. This method, specifically the mixed population method, utilizes the Chinese hamster cell line V79 to detect damage to chromosomes or the mitotic apparatus caused by water-soluble substances. Essentially, it's a way to assess whether a water sample is likely to cause genetic damage in cells.
