Bromomethane
Health Effects
EPA's Integrated Risk Information System classifies Bromomethane as: D; not classifiable as to human carcinogenicity. EPA's stated basis: "Inadequate human and animal data: a single mortality study from which direct exposure associations could not be deduced and studies in several animal species with too few animals, too brief exposure or observation time for adequate power. Bromomethane has shown genotoxicity." EPA's oral reference dose for Bromomethane is 1.4 mg/kg/day, based on a critical effect of "Epithelial hyperplasia". EPA has not set a federal drinking-water limit (MCL or MCLG) for Bromomethane; IRIS assesses a chemical's toxicity, not the amount permitted in tap water.
