Bioconcentration of Nitro Musk Compounds NMCs

In the MITI list for musk xylene a log value of 5.20 was published [340]. Rimkus et al. [344] determined by reversed-phase HPLC a log value of 4.90. [Pg.131]

From this log value we estimated by means of a Quantitative Structure-Activity Relationship (QSAR) of Mackay [345] a BCFw for musk xylene of about 3,800 and a BCFl of 79,200 for this compound in fish [346]. The predicted BCFw of musk ketone (log K(, = 4.20 [344]) was 760 and the BCFl 15,800 [346]. These data, the chemical structures, n-octanol/water partition coefficients (log Ko s) [Pg.131]
