Description of key information

Simulation testing on ultimate degradation in surface water and sediment is not deemed necessary, since subcategory 1a members, including edetic acid (CAS 60-00-4), are biodegradable in ready biodegradation tests under enhanced conditions. Thus, the substance is not considered to be persistent in water and sediment.

Key value for chemical safety assessment

Additional information

Due to the enhanced biodegradability, simulation tests are not mandatory for EDTA (acid form).
