Conclusions:
On the basis of effects observed in a static freshwater system, the NOEC value for the substance is estimated to be 13.280 mg/l for aquatic invertebrate for 21 days of exposure duration.
Executive summary:

Based on the prediction done using ECOSAR version 1.1, the long term toxicity on aquatic invertebrate was predicted for test substance . On the basis of effects observed in a static freshwater system, the NOEC value for the substance 1-phenylethan-1 ol(98 -85 -1) is estimated to be 13.280 mg/l for aquatic invertebrate for 21 days of exposure duration.Since, the test substance is readily biodegradable , it can be concluded that the test chemical 1-phenylethan-1 ol(98 -85 -1) can be considered as non-toxic to aquatic invertebrate at environmentally relevant concentrations and can be considered not-classified as per the CLP classification criteria.
