ISO 21427-1:2006 is an international standard that specifies a method for evaluating the genotoxicity of water using amphibian larvae. It's part of a series of ISO standards (21427) focused on assessing genotoxicity, which refers to the ability of a substance to cause damage to the genetic material (DNA) of an organism. Specifically, this part 1 uses amphibian larvae to measure the induction of micronuclei, a sign of chromosomal damage.
