Description of key information

Simulation testing on ultimate degradation in surface water and sediment is not deemed necessary, since subcategory 1a members, including Diammonium dihydrogen ethylenediaminetetraacetate (CAS 20824-56-0), 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
