Additional information

Conclusion on classification

Based on the results of the available studies, the substance warrants classification as Acute Category 1 and Chronic Category 2 with regards to its effects on the environment. The study on the effects of the substance on aquatic invertebrates (daphnia) by Drottar et al (2001) indicates that the short term effects of the substance are sufficient to result in the above mentioned acute classification. Similarly the study on the long-term toxicity to aquatic invertebrates (daphnia) by Maeda (2003) in combination with the substance's lack of ready biodegradability is sufficient to result in the abovementioned chronic classification.
