Description of key information

Benzaldehyde is reported to be readily biodegradable. It can be degraded by direct reaction with sunlight (slowly) or indirectly by reaction with photochemically produced hydroxyl and nitrate radicals. No data were available on the potential for hydrolysis. Benzaldehyde has a low log Kow therefore it is not expected to bind to organic matter in soils and sediments or be bioaccumulative.

Additional information

The test substance is readily biodegradable. The test substance was shown to degrade under influence of light with a DT50 of 9.4 hours. In adddition under anaerobic conditions complete biodegradation is expected.

As the logKow is 1.4, the potential for bioaccumulation and sorption of the test substance is considered to be low. The Henry Constant was calculated to be 2.85 Pa m3/mol. A calculation with Simple Treat shows that the test substance will degrade in the Sewage Treatment Plant for > 88% with at maximum about 12% to end up in the water compartment.
