- Conclusions:
- The effect concentration (EC50) and (NOEC) for long term toxicity of test material on aquatic invertebrate was observed to be 0.72 mg/l and 0.35 mg/l
- Executive summary:
Long term toxicity of aquatic invertebrate was evaluated for aquatic invertebrtae for 21 days under static conditions. The effect concentration (EC50) and (NOEC) for long term toxicity of test material on aquatic invertebrate was observed to be 0.72 mg/l and 0.35 mg/l.On the basis of above effect concentration it can be considered that test chemical 1,2-di(ethenyl)benzene can be toxic to aquatic invertebrate in longg term and can be classified as aquatic chronic-2
