The acute toxicity of 1,4 -Butanediol to freshwater fish has been tested
according to various guideline and non-guideline methods under GLP and
non-GLP conditions. Test results of a study completed according to OECD
Method 203 yield a 96 hr LC50 value of >100 mg/L and a 96 hr LC0 value
of >100 mg/L (BASF AG 2005). Additional test results from reliable data
sources include a 48 hour LC50 value of 427 mg/L (BASF 1977), and a 24h
LC50 value of >5 mg/L (Hollis et al. 1954). These data indicate that 1,4
-Butenediol has a very low degree of toxicity to freshwater fish.
