Description of key information

96 hrs aquatic toxicity study (EPI suite, 2016) was conducted to assess toxic effects of the test compoundBenzenamine, N-phenyl-, styrenated(CAS No. 68442-68-2)and the results were predicted. The study was based on the effects of the test compound on green algae in a static fresh water system. The predicted data suggests the effective concentration (EC50) for the test compoundBenzenamine, N-phenyl-, styrenated(CAS No. 68442-68-2) was estimated to be 0.39 mg/L on the basis of growth rate.Thus based on this value it can be concluded that the substance can be classified as Aquatic acute category 1 as per the criteria of CLP regulation.

72 hrs aquatic toxicity study (SSS QSAR prediction model, 2016) was predicted to assess toxic effects of the test compoundBenzenamine, N-phenyl-, styrenated(CAS No. 68442-68-2) and the results were predicted. The study was based on the effects of the test compound on Scenedesmus subspicatus in a static fresh water system. The predicted data suggests the effective concentration (EC50) for the test compoundBenzenamine, N-phenyl-, styrenated(CAS No. 68442-68-2) was estimated to be 1.5639 mg/L on the basis of growth rate. Thus based on this value it can be concluded that the substance can be classified as Aquatic chronic category 2 as per the criteria of CLP regulation.

72 hrs aquatic toxicity study (Danish (Q)SAR Database, 2016) was predicted to assess toxic effects of the test compoundBenzenamine, N-phenyl-, styrenated(CAS No. 68442-68-2) and the results were predicted. The study was based on the effects of the test compound on Pseudokirchneriella spp. in a static fresh water system. The predicted data suggests the effective concentration (EC50) for the test compoundBenzenamine, N-phenyl-, styrenated(CAS No. 68442-68-2) was estimated to be 2.369 mg/L on the basis of growth rate. Thus based on this value it can be concluded that the substance can be classified as Aquatic chronic category 2 as per the criteria of CLP regulation.

Based on the information observed for the test chemical, it is summarized thatBenzenamine, N-phenyl-, styrenated(CAS No. 68442-68-2) can be classified as Aquatic acute category 1 as per the criteria of CLP regulation.
