Description of key information
The biodegradation of trisodium EDDS was assessed in an activated sludge simulation test (DOC removal) conducted according to OECD Guideline 303 A and in compliance with GLP. The mean DOC removal value, based on 17 measurements taken between days 8-30 (with one result excluded) was 95.6% (SD 3.3%). Therefore, trisodium EDDS was shown to be readily biodegradable (Geukens, 1993b; Schowanek et al. 1997).
