Description of key information
The effect of test item 3-phenoxybenzylic alcohol, CAS No.13826-35-2 was studied on the growth of fresh water green alga Chlorella vulgaris.The study was conducted following OECD guideline 201- Alga growth inhibition test. The test concentration chosen for the study were 0.21mg/L, 0.63mg/L, 1.89mg/L, 5.67 mg/L, 17.01mg/L and 51.03mg/L. The test concentrations were prepared using stock solution of the test item using mineral media. 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 the test item. EC50 calculated graphically through probit analysis was observed to be 13.498 mg/L.
