Additional information

The acute aquatic toxicity of ´2-Propyn-1-ol, compound with methyloxirane´ on fish was investigated in a GLP guideline study according to DIN 38 412, part 15 [BASF AG, 1987]. In this static test with Leuciscus idus as test species the LC50 after 96 hours was circa 460 mg/L (nominal). Hence, the test substance is not considered to be acutely harmful to fish.
