Hazard T+: Very toxic;N: Dangerous for the environment;
Risk R24/25;R26;R36/37/38;R48/25;R50/53
Safety

Poison by ingestion and intraperitoneal routes. Mutation data reported. Human systemic effects: changes in structure or function of esophagus, diarrhea, edema, fibrosis of lung, fibrosis, focal (pneumoconiosis), hemorrhage, jaundice, renal damage, renal function tests depressed, respiratory depression, ulceration or bleeding from stomach, vomiting. Death from anoxia may result. When heated to decomposition it emits toxic fumes of NO_x. See also PARAQUAT DICHLORIDE. Pure paraquat ingested is highly toxic to mammals and humans potentially leading to acute respiratory distress syndrome (ARDS), and there are no specific antidotes. Even a single swig, immediately spat out, can cause death from fibrous tissue developing in the lungs leading to asphyxiation.
