Description of key information

2 mg p-TSA/L was readily biodegradable and was not toxic to the microorganisms.

Key value for chemical safety assessment

Biodegradation in water:
readily biodegradable

Additional information

Two valid studies are available on the biodegradability of p-TSA. One is a publication, valid with restrictions, in wich the degradation pathway is described and from which can be concluded that p-TSA is readily biodegradable. The other study is a full GLP Closed bottle Test according to standard guideline, valid without restrictions, from which can be concluded that 2 mg/L p-TSA was readily biodegradable and was not toxic to the microorganisms as the toxicity control with Acetate showed.
