Description of key information

Ready biodegradability of the main constituent trisodium trioxalatoferrate was assessed in the Modified OECD Screening Test according to OECD guideline 301E. The test item was exposed to aerobic activated sludge from the aeration tank of a domestic waste water treatment plant for 28 days. Biodegradation was evaluated based on DOC removal. The biodegradability of the test item was calculated to be 99 % after 28 days of incubation. The test item reached the pass level of 70 % for ready biodegradability within the 10 day window and can therefore be termed as readily biodegradable.
