Description of key information
Short term toxicity to fish:
Study was conducted to access the effect of test chemical1-phenylethan-1-olon the growth of fish Danio rerio. Test conducted according to OECD Guideline 203 (Fish, Acute Toxicity Test).The test substance was soluble in water. Therefore, the test solution was prepared by dissolving 1ml of the test substance in 10 liters of potable water (passed through reverse osmosis system) with continuous stirring for achieving test concentrations of 100 mg/L, respectivelyand Zebra FishDanio reriowere exposed to these concentration for 96 hours.Bowl aquaria containing 2 liters of potable water (passed through reverse osmosis system) were loaded with 8 fishes. A static procedure was used for the study and it was conducted in compliance with the OECD guideline 203. After 96 hours of exposure to test item1-phenylethan-1-olto various nominal test concentrations, LC50 was determine to be >100 mg/l . Based on the LC50, it can be consider that the chemical was1-phenylethan-1-oland can be consider to be not classified as per the CLP classification criteria.
Long term toxicity to fish:
Based on the prediction done using ECOSAR version 1.1, the long term toxicity on fish was predicted for test substance . On the basis of effects observed in a static freshwater system, the NOEC value for the substance1-phenylethan-1 ol(98 -85 -1)is estimated to be 26.481 mg/l for fish for 28 days of exposure duration.Since, the test substance is readily biodegradable , it can be concluded that the test chemical1-phenylethan-1 ol(98 -85 -1)can be considered as non-toxic to fish at environmentally relevant concentrations and can be considered not-classified as per the CLP classification criteria.
Short term toxicity to aquatic invertebrates:
Aim of this study was to assess the short term toxicity of1-phenylethan-1 olto aquatic invertebrates daphnia magna. Study was performed according to the OECD Guideline 202 (Daphnia sp. Acute Immobilisation Test) in a static system for the total exposure period of 48 hrs.The solution of colourless liquid of purity 99.62% 100 mg/l was prepaired by dissolving the substance into reconstitued test water.. 100 mg/l nominal concentrations were used in the study. Effects on immobilisation were observed for 48 hours. With the test substance one positive control Potassium dichromate (K2Cr2O7) was also run simultaneously. After the exposure of chemical, effect concentration EC50 was calculated using nonlinear regression by the software Prism 4.0.
The inhibition perccentage [%] for the test substance1-phenylethan-1 ol, in Daphnia magna was determined to be 4.0% on the basis of mobility inhibition effects in a 48 hour study.24 out of 25 daphnids were observed to be mobile in the sample. Based on the [I%] value, indicates that the substance is likely to be non-hazardous to aquatic invertebrates and cannot as per the CLP criteria.

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.
Toxicity to aquatic algae and cyanobacteria:
The study was designed to assess the toxic effects of the test compound1-phenylethanol(CAS No. 98-85-1)o n the green alga Chlorella vulgaris. Test was conducted in compliance with the OECD guideline 201 (Alga, Growth Inhibition Test). Test was carried out in 100mL conical flasks which were carefully autoclaved and sterilized. The test solution in each of these test vessels was kept constant which is 60 ml so that a sufficient amount of head space was left. The test substance1-phenylethan-1 olwas prepared by adding 50 mg of test item in 250 ml of BBM to get the final concentration of 200mg/L. This stock solution was kept for stirring/ sonication for 0 minutes to obtain a homogenous solution for the experiment. The test concentrations6.25 mg/l, 12.5 mg/l, 25 mg/l, 50 mg/l, 100 mg/l and 200mg/lwere chosen according to the available data of the test item. The concentrations chosen were set up to the water solubility limit. The remaining test solutions were prepared by dilution from the above stock solution.
For the assessment of algal growth, the test was conducted in replicates. The control flask was maintained in triplicates as recommended in the OECD guideline and the test concentration were selected in geometric series which were maintained in duplicates. To obtain a quantitative concentration-response relationship by regression analysis, a linearizing transformation of the response data into probit was performed. Using the same, effective concentration (EC) were determined. Algal growth was calculated daily by counting the cells microscopically with the help of haemocytometer. For microscopic observations the cultures were observed daily with the help of a microscope to verify a normal and healthy appearance of the algal culture and also to observe any abnormal appearance of the algae (as may be caused by the exposure of the test item). Apart from this, the cell count of each test vessel was also noted with the help of a microscope and haemocytometer. By spectrophotometer the absorbance values of each test vessel and control vessel was noted at 680nm.The BBM was taken as blank for both control and test vessels. The absorbance value of each vessel was in line with the average specific growth rate. As per OECD 201, the biomass in the control cultures should have increased exponentially by a factor of at least 16 within the 72 hr test period. This corresponds to a specific growth rate of 0.92 per day. Thus, the observed specific growth rate in the control cultures during the experiment was 0.358 per day. Secondly the mean coefficient of variation for section by section specific growth rates (days 0-1, 1-2 & 2-3, for 72 hr tests) in the control cultures must not exceed 35%. Thus, the observed mean coefficient of variation in the control cultures during the experiment was 33.42%. Thirdly the coefficient of variation of average specific growth rates during the whole test period in replicate control cultures must not exceed 10%. Thus, the observed coefficient of variation of average specific growth rates during the experiment in control cultures was 8.26%. Hence, the test is considered valid as per OECD guideline, 201. After 72 hours of exposure to test item1-phenylethan-1 olto various nominal test concentrations, EC50 was determine to be >200 mg/l graphically and through probit analysis. Based on the EC50, it can be concluded that the chemical was not toxic and can be consider to be not classified as per the CLP classification criteria.
