- Details on results:
- The results of the read-across approach from the experimental data obtained for the supporting substance are expressed as the estimated toxicity based on molecular weights. No other adaptation is necessary.
- Validity criteria fulfilled:
- yes
- Conclusions:
- Based on the read-across approach, the target substance is not expected to be inhibitory.
- Executive summary:
A toxicity control was performed during the biodegradability testing of the analogue substance naringin, according to OECD 301F (GLP study). The solutions containing 100 mg/l, of both the test and a reference item, in the mineral medium, were inoculated. The consumption of oxygen was determined from the change in pressure in the apparatus. The carbon dioxide, evolved during test item degradation, was absorbed in a solution of potassium hydroxide. The amount of oxygen taken up by the test item (corrected for uptake by blank inoculum, run in parallel) was expressed as a percentage of calculated ThOD of the test item. Under test conditions, the test item was not inhibitory, reaching a degradation of 54.1% after 14 days, and readily biodegradable. Based on the read-across approach, the target substance is not expected to be inhibitory.

- Executive summary:
A toxicity control was performed during the biodegradability testing of the analogue substance neohesperidin dihydrochalcone, according to OECD 301F (GLP study). The solutions containing 100 mg/l, of both the test and a reference item, in the mineral medium, were inoculated. The consumption of oxygen was determined from the change in pressure in the apparatus. The carbon dioxide, evolved during test item degradation, was absorbed in a solution of potassium hydroxide. The amount of oxygen taken up by the test item (corrected for uptake by blank inoculum, run in parallel) was expressed as a percentage of calculated ThOD of the test item. Under test conditions, the test item was not inhibitory, reaching a degradation of 47.2% after 14 days, and it was readily biodegradable. Based on the read-across approach, the target substance is not expected to be inhibitory.

Description of key information
Weight of evidence: Based on the read-across approach from two analogue substances, the target substance is not inhibitory to microorganisms at 99.7 mg/L (worst-case scenario). Furthermore, the substance is readily biodegradable.
- Method according to OECD 301F, GLP study. The test item was not inhibitory to microorganisms (54.1% biodegradation in 14d) at a concentration of 100 mg/L, so the EC50 value of the test item in microorganisms is > 100 mg/L. Based on the read-across approach, the target substance is not expected to be inhibitory, with a calculated NOEC of 105.1 mg/L.
-Method according to OECD 301F, GLP study. The test item was not inhibitory to microorganisms (42.7% biodegradation in 14d) at a concentration of 100 mg/L. Therefore, the EC50 value of the test item in microorganisms is > 100 mg/L. Based on the read-across approach, the target substance is not expected to be inhibitory, with a calculated NOEC of 99.7 mg/L.
