Endpoint:
toxicity to soil macroorganisms except arthropods: long-term
Data waiving:
exposure considerations
Justification for data waiving:
the study does not need to be conducted because direct and indirect exposure of the soil compartment is unlikely

Description of key information

No key study available, however further testing on terrestrial toxicity is not justified.

Key value for chemical safety assessment

Additional information

Few short- and long-term studies were performed with soil macro-organisms, however, no key study has been identified.

From supporting information there is no indication for toxicity to soil macro-organisms.

In accordance with column 2 of REACH Annex IX and X, studies on terrestrial toxicity do not need to be conducted as the substance has a low potential for adsorption (log Kow = 2.53). No significant concentrations are expected in the soil compartment. This is supported by exposure assessment carried out using CHESAR, indicating low exposure to the terrestrial compartment.

The PNEC soil was derived by equilibrium partitioning method. All the relevant RCRs derived from exposure assessment are well below 1, therefore the available information can be considered sufficient. In conclusion further testing on terrestrial toxicity is not justified.
