P273 P501 |
It was classified in Category 2 from 96-hour LC50 = 2.6 mg/L for fish (Pimephales promelas) (Results of Eco-toxicity tests of chemicals conducted by Ministry of the Environment in Japan, 2008). |
| 11 | Hazardous to the aquatic environment （Long-term） | Category 2 |  |
H411 |
P273 P391 P501 |
If chronic toxicity data are used, then it is classified as "Not classified" from lack of rapid degradability (a degradation rate by BOD: 3 to 4 % (the existing chemicals survey program, 1987)) and 72-hour NOEC = 1.7 mg/L for algae (Pseudokirchneriella subcapitata) (Results of Eco-toxicity tests of chemicals conducted by Ministry of the Environment in Japan, 2006). If acute toxicity data are used for trophic levels for which chronic toxicity data are lacking, then it is classified in Category 2 from lack of rapid degradability (a degradation rate by BOD: 3 to 4 % (the existing chemicals survey program, 1987)) and 96-hour LC50 = 2.6 mg/L for fish (Pimephales promelas) (Results of Eco-toxicity tests of chemicals conducted by Ministry of the Environment in Japan, 2008). It was classified in Category 2 by a comparison between the above results. |
| 12 | Hazardous to the ozone layer | Classification not possible | - | - | - | This substance is not listed in Annexes to the Montreal Protocol. |
