Conclusion on classification
Classification
Based on ZMB2 test data, ZMB2 is considered to be classified for the environment based upon the lowest chronic toxicity score for aquatic species, the partition coefficient result and the ready biodegradation result.
NOEC (21 day) Daphnia magna: 0.0346 mg/L
EC50 (48 hours) Daphnia magna: 1.4 mg/L
Log Pow: 0.4
Ready biodegradation: 27% after 28 days (inherently biodegradable)
ZMB2 is therefore considered to be classified as Chronic Category 1 H410: Very toxic to aquatic life with long lasting effects according to Table 4.1.0 and Table 4.1.4 of EC Regulation 1272/2008, and N; R51/53 Dangerous for the environment; Toxic to aquatic organisms, may cause long-term adverse effects in the aquatic environment in accordance with Annex VI of Directive 67/548/EEC.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
