WebThe mutagenicity/genotoxicity assays are the most commonly used in vitro test systems to predict carcinogenicity. According to UN Globally Harmonized System (GHS) guidance, chemical-induced tumorigenesis involves genetic changes; thus, chemicals that are mutagenic in mammals may warrant being classified as carcinogens [139]. WebThe topics of genotoxicity, mutagenicity, and carcinogenicity are introduced in the course Toxicology for Hazard Communication. The goal of this course is to provide participants with an understanding of the topics of genotoxicity, mutagenicity, and carcinogenicity.
