Description of key information

No endpoints are available for the effects of biphenyl-4,4'-diol on terrestrial organisms. They are judged not necessary.

Additional information

No endpoints are available for the effects of biphenyl-4,4'-diol on terrestrial organisms. Studies to address terrestrial toxicity data points have been waived on the grounds that significant direct and/or indirect exposure of the terrestrial compartment to biphenyl-4,4'-diol is unlikely to occur. Under these circumstances, test data for the effects of biphenyl-4,4'-diol on terrestrial organisms are considered to be unnecessary.

No risk to terrestrial biota was indicated in a chemical safety assessment performed according to Annex I, based on a PNEC for the soil compartment that has been derived from the aquatic toxicty data set using the equilibrium partitioning method. As the PNEC soil is typically greatly underestimated by this method, it is considered that this is sufficient to demonstrate the absence of unacceptable risk to biota of the terrestrial compartment.
