Description of key information

With high probability acutely not harmful to aquatic invertebrates.

Key value for chemical safety assessment

EC50/LC50 for freshwater invertebrates:
500 mg/L
EC50/LC50 for marine water invertebrates:
320 mg/L

Additional information

Parent compound methyl formate Data on acute toxicity to aquatic invertebrates are available for Daphnia magna and a marine species. The Daphnia magna study was performed according to EU Method C.2 in a static test system. The 48 -h EC50 is > 500 mg/L, related to the nominal concentration (BASF AG, 1988). With the marine Crustacea Chaetogammarus marinus a 96 -LC50 of 320 -560 mg/L was determined (Adema & Bakker, 1984). In conclusion, no harmful effects to aquatic invertebrates are to be expected.

Hydrolysis product formic acid/formate

After 48 hours of exposure of Daphnia magna to ammonium formate in a GLP study following OECD TG 202, an EC50 of

365 mg/L (nominal, verified analytically) was determined (Fraunhofer, 2005).

In a static saltwater study according to a national British guideline using brown shrimp (Crangon crangon) an LC50 (96h) of 1308 mg/L was found (Huntington, 1992).

Hydrolysis product methanol

In the key study with Daphnia magna no adverse effects were reported up to 10000 mg/L after 48 -h exposure (Kuehn, 1989).
