EC number: 231-640-0 | CAS number: 7665-72-7
In a 96 -h acute toxicity study, Pimephales promelas Rafinesque (fathead minnows) were exposed to tertiary butyl glycidyl ether (t-BGE) at nominal concentrations of 144.00, 155.00, 167.00, 180.00 and 194.00 mg/L under static conditions. The 96-h LC50was 172 mg/L. The NOAEL value, based on mortality, was <135 mg/L, respectively. Sublethal effects were not mentioned. Based on the results of this study with P. promelas Rafinesque, t-BGE does not have to be classified as hazardous to fish in accordance with Section 184.108.40.206., Annex I of Regulation 1272/2008/EC.
This toxicity study is classified as acceptable and satisfies the guideline requirement for acute toxicity studie with fish.
Test organism size/age (mean wet weight or length): 2.8 cm

Endpoint(s) Effected: Mortality
In a 96-hr-static acute fish test the test material t-BGE showed low toxicity to fish. The 96-hour LC50 for fish (Pimephales promelas Rafinesque) was 172 mg/L (95 %-C.I.: 165-182 mg/L).
