Additional information
Regarding toxicity to aquatic freshwater and marine water invertebrates, two studies each are available. Freshwater invertebrates were tested in two tests owned by Kemira Oyi (1992; 2005). These tests were performed using Daphnia magna as test species in static approaches according to OECD guideline 202. Both tests used analogous substances, one test was performed with ammonium formate the other test with potassium formate. After 48 hours of exposure, the test using ammonium formate revealed an EC50 of
365 mg/L (nominal, verified analytically) while for the other test using potassium formate an EC50 of 540 mg/L was estimated (nominal, no analytical test item verification).
The two tests on marine invertebrates applied potassium formate as test substance. The first test according to a national british guideline was performed using brown shrimp (Crangon crangon) as test species (Huntingdon on behalf of Kemira Oyi, 1992). In the static approach a LC50 (96h) of 1308 mg/L was found.The second test used the marine copepod Acartia tonsa as test organism (Binnie Environment on behalf of Osca UK Ltd.). After 48 hours, a nominal LC50 of 531 mg/L was estimated.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
