1. Ecotoxicity: EC50: 1.2 ~ 1.51mg/l (Luminescent bacteria, Microtox toxicity test).

2. Biodegradability: MITI-I test showed that the initial concentration was 100mg / L, the sludge concentration was 30mg / L, and the degradation rate was 77% after 2 weeks.

3. Non biodegradability: in air, when the concentration of hydroxyl radical is 5.00 × At 105 / cm3, the degradation half-life is 7.8d (theoretical).

4. It is harmful to the water body, especially to the environment.
