Additional information

Key study. Read-across approach. BCF values of 432 -922 L/kg and 606 -1290 L/kg were measured in fish for Camphene at concentrations of 15 and 1.5µg/L, respectively, using carp (Cyrpinus carpio) which were exposed over a 8 -week period. Test method was according to OECD guideline 305 C. Based on these results, the read-across approach was applied and the BCF of the reaction mass was determined as a maximum of 1290 L/kg.

Supporting studies: Data from EPI-Suite, EPA (USA) / BCFBAF v3.01 calculation method. The BCF of the main components of the reaction mass were calculated to be in the range of 283 -395 L/kg.

According to Annex XIII to REACH, the substance is considered not to fulfil the criterion for bioaccumulation, since the estimated BCF (BCF = 1290 L/kg wet-wt) is < 2000.
