Additional information

No data for Diethyl oxalate is available. Long-term toxicity to aquatic invertebrates were tested on the hydrolyses product oxalic acid (CAS 144 -62 -7) and ethanol (CAS 64 -17 -5). According to OECD guideline 221 Daphnia magna reveals an NOEC (21 d) of 9.3 mg/L for oxalic acid (NITE 1998). Long-term toxicity test of ethanol on Daphnia reveals LC50 (10 d) of 454 mg/L (Cowgill & Milazzo 1991).
