1. It irritates the respiratory and gastrointestinal mucosa, and is toxic to blood vessels and nerves, causing vasospasm, congestion, or hemorrhage; it has a specific selective effect on the optic nerve and retina, causing retinal necrosis due to lack of nutrition.
2. Ecotoxicity LC50: 15.4~29.4 g/L (96h) (Blackhead carp)
3. Biodegradability MITI-I test: initial concentration 100 ppm, sludge concentration 30 ppm, 92% degradation after 2 weeks.
4. Non-biodegradability: In air, when the concentration of hydroxyl radicals is 5.00 × 10⁵ ions/cm³, the degradation half-life is 17 days (theoretical).
