Abstract:Uptake rate constants of 10 chloroanisoles by fish are comparable to those of other hydrophobic chemicals. Since fast elimination is found for all congeners the resulting bioconcentration factors are lower than those predicted from their hydrophobicities. Elimination is mainly due to metabolism at the ether bond and the rate constants are independent of hydrophobicity. The presence of the ether bonds does not influence the octan-1-ol/water partition coefficient of the chlorinated aromatic hydrocarbons significantly.
