Description of key information

The readily biodegradation of Guanidine phosphate (1:1) under the conditions of the carbon dioxide (CO2) evolution test (modified Sturm test) was investigated according to OECD guideline 301 B and GLP principles. Based on the obtained results, Guanidine phosphate (1:1) was not readily biodegradable. The study is considered to be reliable (Klimisch score 1).

Key value for chemical safety assessment

Biodegradation in water:
under test conditions no biodegradation observed

Additional information

The readily biodegradation of Guanidine phosphate (1:1) under the conditions of the carbon dioxide (CO2) evolution test (modified Sturm test) was investigated according to OECD guideline 301 B and GLP principles. A single test concentration of 14 mg TOC/L was tested during 28 days. Based on the obtained results, Guanidine phosphate (1:1) was not readily biodegradable. The study is considered to be reliable (Klimisch score 1).
