Water solubilities were measured for 10 disperse dyes that are mostly of recent vintage. The solubilities and octanol/water partition coefficients are used to predict expected concentration factors for sediment and biota. The results show that these newer disperse dyes are likely to have greater potential toward sediment sorption and bioconcentration than older dyes. The data also confirm a previous conclusion that methods for estimating the octanol/water partition coefficient of these dyes give results that are significantly different from measured values. Possible explanations for the differences are discussed.
