Description of key information

LC50 (96hr) =140mg/l

Key value for chemical safety assessment

LC50 for freshwater fish:
140 mg/L

Additional information

A 96-hour guideline and GLP aquatic toxicity study (semi-static) of ethoxypropyl acetate in Rainbow Trout produced a 96-hour LC50 of 140 mg/L (95% CL 120-170) and an LC0 = 100 mg/L. Reactions to exposure (narcosis, balance and stringy faeces) were observed at all concentrations tested; therefore a NOEC for symptoms other than mortality was not established.
