Fate
Toxicology
Mammals: Very toxic to mammals. Acute oral LD50 for rats 10-15 mg/kg (acid), 6.44 mg/kg (sodium salt). In man, exposure for 30 minutes at 0.3 mg/l air is normally fatal. Rapidly absorbed by skin. Eye irritant. Birds: Toxic to birds. Fish: Toxic to fish. Bees: Toxic to bees, but not dangerous if used as directed.
