Description of key information
72 hrs aquatic toxicity study was predicted to assess toxic effects of the test compound 3-Phenylpropyl acetate (CAS no. 122 -72 -5) and the result were predicted (SSS QSAR Prediction Model, 2016). The study was based on the effects of the test compound on Pseudokirchnerella subcapitata in a static fresh watersystem. The predicted data suggests the effective concentration (EC50) for the test compound 3-Phenylpropyl acetate (CAS no. 122 -72 -5) was estimated to be 55.548 mg/l on the basis of growth rate. Thus, based on this value, it can be concluded that the test chemical 3-Phenylpropyl acetate can be considered as toxic to aquatic organisms and thus can be classified as aquatic chronic cateogry 3. Since the test chemical is readily biodegradable in nature, chemical 3-Phenylpropyl acetate can be considered as non-toxic to aquatic organisms and thus cannot be classified as hazardous as per the CLP criteria.

Additional information
Various predicted data for the target chemical 3-Phenylpropyl acetate(CAS No. 122-72-5) and the study for its read across substance were reviewed to summarize the following information:
72 hrs aquatic toxicity study was predicted to assess toxic effects of the test compound 3-Phenylpropyl acetate (CAS no. 122 -72 -5) and the result were predicted (SSS QSAR Prediction Model, 2016). The study was based on the effects of the test compound on Pseudokirchnerella subcapitata in a static fresh water system. The predicted data suggests the effective concentration (EC50) for the test compound 3-Phenylpropyl acetate (CAS no. 122 -72 -5) was estimated to be 55.548 mg/l on the basis of growth rate. Thus, based on this value, it can be concluded that the test chemical 3-Phenylpropyl acetate can be considered as toxic to aquatic organisms and thus can be classified as aquatic chronic cateogry 3. Since the test chemical is readily biodegradable in nature, chemical 3-Phenylpropyl acetate can be considered as non-toxic to aquatic organisms and thus cannot be classified as hazardous as per the CLP criteria.
Based on the QSAR prediction done using the EPI Suite ECOSAR version 1.10 (EPI Suite, 2016), the 96 hours EC50 was estimated to be 11.377 mg/l on green algae for substance 3-Phenylpropyl acetate (CAS no. 122 -72 -5) with growth inhibition effects. Thus, based on this value, it can be concluded that the test chemical 3-Phenylpropyl acetate can be considered as toxic to aquatic organisms and thus can be classified as aquatic chronic cateogry 3. Since the test chemical is readily biodegradable in nature, chemical 3-Phenylpropyl acetate can be considered as non-toxic to aquatic organisms and thus cannot be classified as hazardous as per the CLP criteria.
The effect of read across substance Methyl phenylacetate, CAS No. 101-41-7 was studied on the growth of fresh water green alga Chlorella vulgaris (UERL study report, Sustainability Support Services (Europe) AB, AT-025/101-41-7/2015, 2015).The study was conducted following OECD guideline 201- Alga growth inhibition test. The read across substance concentration chosen for the study were 6.25 mg/l, 12.5 mg/l, 25 mg/l, 50 mg/l, 100 mg/l and 200 mg/l were prepared using stock solution of Methyl phenylacetate using de-ionized water. The green alga was exposed to the test concentration for a period of 72 hours to observe average specific growth rate and % growth inhibition under the effect of read across substance. EC50 calculated graphically through probit analysis was observed to be 220.89 mg/l. Thus, based on this value, it can be concluded that the chemical Methyl phenylacetate can be considered as non-toxic to aquatic organisms and thus cannot be classified as hazardous as per the CLP criteria.
A 72 h algae inhibition test was conducted according to the OECD Guideline 201 (Alga, Growth Inhibition Test) (A.M. Api, et. al; 2015). Based on the effect on growth rate of the test organism, the 72 hrs EC50 value was determined to be 110 mg/l, respectively. Thus, based on the EC50 value, it can be concluded that the read across substance Benzyl acetate (CAS no. 140-11-4) can be considered as non-toxic to aquatic organisms and thus cannot be classified as hazardous as per the CLP criteria.
Short term toxicity to Scenedesmus subspicatus (green algae) study was carried out for 30 or 60 mins (Monika Nendzal and Andrea Wenzel, 2006). The study was based on the effects of the read across compound tert-Butyl acetate (CAS no. 540-88-5) on Scenedesmus subspicatus in a static fresh water system. Inhibition of photosynthesis (EC50) was determined from effects on O2-production in unicellular green algae Scenedesmus subspicatus, cultured according to OECD-Guideline No. 201 [20]. 5 ml of algae suspension (2 million cells/ml) were collected on a filter paper disk (diameter 13 mm). After incubation in test solution for 30 or 60 min, the disk was placed on top of the electrode of the measuring chamber (PHOSY-Mess 2000, Specht, Germany). The Clark-electrode was placed in the measuring chamber (25°C, 100% exposure (ca. 1.9 klux), measuring solution: 0.05 M KHCO3). After a dark phase of 5 min (O2 fell to nearly 0 mg/l), the O2-production [mg/l] was recorded for 14 min.
On the basis of inhibition of photosynthesis of the test organism Scenedesmus subspicatus (green algae), the EC50 value was determined to be 1500 mg/l, respectively. Thus, based on this value, it can be concluded that the substance tert-Butyl acetate can be considered as non-toxic to aquatic organisms and thus cannot be classified as hazardous as per the CLP criteria.
Short term toxicity to Chlorella zofingiensis (green algae) study was carried out for 24 hrs (GSBL database, 2016). The study was based on the effects of the read across compound tert-Butyl acetate (CAS no. 540-88-5) on Chlorella zofingiensis in a static fresh water system. On the basis of assimilation of the test organism Chlorella zofingiens is (green algae),the 24 hr EC10 and EC50 value was determined to be 280 and 1300 mg/l, respectively. Thus, based on this value, it can be concluded that the substance tert-Butyl acetate can be considered as non-toxic to aquatic organisms and thus cannot be classified as hazardous as per the CLP criteria.
Based on the overall reported results for target and its read across substance, it can be concluded that the test substance 3-Phenylpropyl acetate can be considered asnon-toxic to aquatic organisms and thus cannot be classified as hazardous as per the CLP criteria.
