Description of key information

No data are avaialble on the toxicity of dimethyl terephthalate acid to birds.

Key value for chemical safety assessment

Additional information

This data point has been waived for dimethyl terephthalate on the grounds that contamination of the terrestrial compartment is unlikely, that DMT is readily biodegradable and that primary exposure of terrestrial vertebrates is therefore not expected to occur. Moreover, the log Kow of dimethyl terephthalate is less than 3.0, indicating that its bioconcentration potential is negligible and there is consequently no significant risk of secondary poisoning of birds via earthworms or fish. Under these circumstances, data for the effects of dimethyl terephthalate on birds are considered unnecessary.
