Endpoint summary

Description of key information
Benzaldehyde is shown to be indirectly degraded by reaction with photochemically produced hydroxyl and nitrate radicals. It can also be directly degraded by direct reaction with sunlight. No data on hydrolysis is available but the substance is readily biodegradable and therefore data on hydrolysis is not required.
Additional information
A DT50 of 9.4 h has been predicted for the indirect photolysis of benzaldehyde in air caused by reaction with photochemically produced hydroxyl radicals.
A DT50 of 16.4 days has been predicted for the indirect photolysis of benzaldehyde in air caused by reaction with photochemically produced nitrate radicals.
Direct photolysis of benzaldehyde in air is possible but may be slow and benzene and carbon monoxide and a yellowish polymer have been identified as transformation products.
No data on hydrolysis is available in view of the fact that the test substance is readily biodegradable.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
