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 data are available on the toxicity of biphenyl-4,4'-diol to soil macroorganisms. A PNEC for the soil compartment has been derived from the aquatic toxicity data set using the equilibrium partitioning method.

Key value for chemical safety assessment

Additional information

This data point has been waived for biphenyl-4,4'-diol on the grounds that significant direct and/or indirect exposure of the terrestrial environment is not expected to occur. Under these circumstances, data for the effects of biphenyl-4,4'-diol on soil macroorganisms are considered to be unnecessary.
