The Koc of BMDBM was being calculated via QSPR. As no single computational model could be identified which would fit completely to this task, the Koc of BMDBM eventually was being calculated from the geometric mean of the data generated by four individual QSPR approaches. The four different ways of QSPR computations all were based on the experimentally derived log Kow of BMDBM of 6.1. The final QSPR result of log Koc = 4.65 (Koc = 44242 L/kg) is considered reliable as it is supported from several and different QSPR models. Based on the mobility classification system of McCall (1981), test item BMDBM has to be considered as “immobile” in soil or sediments.
