Description of key information

No measured data are available for long-term toxicity of DTO to fish. A data-waiver is considered to be appropriate for this endpoint on the following grounds:

- The results from short-term tests indicate that fish, invertebrates and algae are similarly susceptible to the substance. Reliable long-term test data for

Crude Tall Oil (CAS No. 8002 -26 -4) show an absence of toxicity to invertebrates at a loading rate of 1 mg/L. The NOELR for algae is also >1 mg/L.

- Calculation of PNECs for the aquatic compartment will be based on data for the blocks of constituents rather than on data for the whole substance.
Testing for long-term toxicity to fish will not therefore contribute to the database that is required to complete the assessment of the substance.
