Toxicity to fish

The test item, Allyl Amyl Glycolate, was tested for acute toxicity on fish Poecilia reticulata. The definitive test was performed under semi-static conditions with a range of the test item nominal concentrations of 10, 5, 2.5, 0.63, 0.32 and 0.16 mg/L. The analytical results showed that test item concemtrations were not stable in dilution water. Therefore time-weighted mean concentrations were used for evaluations and results presentation. Test results: 96 hour-LC50 = 0.30 mg/L (time-weighted mean concentration), 96 hour-LC0 < 0.08 mg/L, 96 hour-LC100 = 1.67 mg/L.

Toxicity to acquatic invertebrates

The test item, Allyl Amyl Glycolate, was tested in acute immobilisation test on Daphnia magna. The test was performed according to method C.2- Daphnia sp. Acute Immobilisation Test. The definitive test was performed under semi-static conditions with a range of the test item nominal concentrations of 10, 6.3, 3.9, 2.4, 1.5, 0.9 and 0.6 mg/L. Because concentrations of the test item have not been satisfactorily maintained within ± 20 percent of the nominal or measured initial concentration, time-weighted mean concentrations were used for evaluations and results presentation. Test results: 48 hour-EC50 = 2.21 mg/L (time-weighted mean concentration), 48 hour-EC0 = 0.44 mg/L, 48 hour-EC100 = 7.62 mg/L.

Toxicity to algae

The test item, Allyl Amyl Glycolate, was tested for growth inhibition on algae Desmodesmus subspicatus. The test was performed according to method C.3. - Freshwater Algae and Cyanobacteria, Growth Inhibition Test. Based on toxicity of the test item found in preliminary test, the full test was performed in a range of the test item nominal concentrations 9, 13, 20, 30, 45, 67 and 100 mg/L. Because the concentrations of test item have not been satisfactorily maintained within ± 20 percent of the nominal or measured initial concentration, the geometric mean of measured concentrations was used for results presentation and evaluation. Test results: 72 hour-EC50 (based on growth rate) = 8.2 mg/L (geometric mean of measured concentrations), 72 hour-EC10 = 1.4 mg/L.

Toxicity to microorganisms

The influence of the test item, Allyl Amyl Glycolate, on the respiration rate of activated sludge was investigated after a contact time of 3 hours. Test was performed according to Method C.11- Activated Sludge Respiration Inhibition Test (Carbon and Ammonium Oxidation) and OECD Test Guideline No.209- Activated Sludge, Respiration Inhibition Test (Carbon and Ammonium Oxidation). The definitive test was performed in a range of test item nominal concentrations 15 -240 mg/L. Test results for the test item: 3 hour-EC50 = 90.5 mg/L (nominal concentration).
