Additional information
In a key study performed by Bengtson et al. (1986) with bleak (Alburnus alburnus) the BCF values for one major component (CDP, cresyl diphenyl phosphate) and two minor components (TPP, triphenyl phosphate and TCP, tricresyl phosphate) of Diphenyl tolyl phosphate MCS were determined. The BCF values for CDP varied between 100 and 220 due to differenct isomeric forms. The higher value was thus chosen as key value for further assessments. TPP and TCP exhibited BCF values of 400 and 800, respectively. These values were further corroborated by an additional feeding study with Phoxinus phoxinus (also performed in the study of Bengtson et al., 1986) which revealed a very low biomagnification potential. Calculated BCF values based on the logKOW for CDP (BCF = 360), TPP (BCF = 420) and TCP (BCF = 750) by Saeger et al.(1979) were well in line with the experimentally determined ones.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
