Description of key information

No data is available for  Alkylation and transalkylation products of biphenyl with propene itself. Based on its very low water-solubility (=<30 µg/L) and experience with structure-related substances, no inhibitory effect on microbial respiration and activity is anticipated.
As starting point for the derivation of a PNEC STP, the non-toxic substance concentration in the toxicity control of a ready biodegradation test with the constituent isopropylbiphenyl is taken. At a substance concentration of 20 mg/L, no inhibitory effects on the inoculum (STP microorganisms) were observed.
