Additional information

For TDCP, good agreement is found between the QSAR predictions of Koc from Kow (Koc= 950.8 (range 633.4 – 1427.2) and the value measured in the OECD 106 study (Koc= 1780 (range 1540 – 2010). The HPLC screening estimates of Koc appear to consistently over-estimate this value for the chloroalkylphosphates. For TDCP, the Koc measured in the OECD 106 study will be used for the risk assessment, Koc= 1780 log Koc= 3.25.
