Two ecotoxicological tests on the substance 1-Pentene are reported. Both were performed under GLP.
Short-term toxicity of 1-Pentene to Daphnia magna was determined. The 48h-EC50 is 35 mg/L.
Toxicity of 1-Pentene to Desmodesmus subspicatus according to OECD 201 resp. EU C.3 was determined. The experiment is valid according to the validity criteria of these guidelines.
The 72h-EC50 (growth rate) is 79 mg/L. The 72h-NOEC (growth rate) is <= 15 mg/L. According to the regulation (CE) 1272/2008, 72h-EC50 (growth rate) should be used for classification. The 72h-EC50 (yield) is 34 mg/L. The 72h-NOEC (yield) is <= 15 mg/L.
According to the available data, the lowest EC50 for aquatic invertebrates and algae are in the range 10 - 100 mg/L.
