Description of key information

No data are available on the toxicity of trimellitic anhydride to other above-ground organisms.

Key value for chemical safety assessment

Additional information

This data point has been waived for trimellitic anhydride on the grounds that contamination of the terrestrial compartment is unlikely, that TMA is readily biodegradable and that primary exposure of terrestrial vertebrates is therefore not expected to occur. Moreover, the log Kow of trimellitic anhydride is less than 3.0 (as is the log Kow of its hydrolysis product, trimellitic acid), indicating that its bioconcentration potential is negligible and there is consequently no significant risk of secondary poisoning of other above-ground organisms via earthworms or fish. Under these circumstances, data for the effects of trimellitic anhydride on other above-ground organisms are considered unnecessary.
