Bioconcentration factors of some halogenated organics for rainbow trout: limitations in their use for prediction of environmental residues

Accumulation of Organochlorine Pesticides from Water Using Triolein Embedded Cellulose Acetate Membranes

“…The estimated partition coefficients of six OCPs and their lipid normalized log BCF values of rainbow trout are also compared as calculated from empirical equations in the literature (18 , Table 3). A significant correlation (P < 0.01) was found between log Ktw and log BCF (n ) 6), with r ) 0.952.…”

Manmade organic compounds in the surface waters of the United States; a review of current understanding

“…The data of Neely and others (1974), not included in the above correlation, resulted in the following relation: log BCF=0.52 log ~w +0.124 with a correlation coefficient of 0.948. Casserly and others (1983) Niimi (1983, 1985), KOnemann and van Leeuwen (1980), and Southworth andothers (1978a, 1978b ). Figure 8 presents a plot of BCF as a function of aqueous solubility for a variety of pesticides…”

“…Similarly, DDT uptake by goldfish did not result in steady-state concentrations even after 50 d (Rhead and Perkins, 1984). Oliver and Niimi (1983) monitored the bioconcentration of a variety of chlorinated benzenes by rainbow trout and noted that, as compound solubility decreased, the time to reach equilibration generally increased. Dichlorobenzene isomers attained equilibrium after 10 d, but pentachlorobenzene did not reach a steady-state concentration after 119 d. The tri-and tetrachlorobenzenes reached equilibrium after about 15 and 50 d, respectively.…”

Hexabromocyclododecane and Hexachlorocyclohexane: How Lessons Learnt Have Led to Improved Regulation

“…A wide range of BCFs for HCH have been reported in several studies. Oliver and Niimi (1985) reported BCF of 1100 -2800 in fish. In invertebrates, BCFs ranging from 60 -2,750 have been estimated (UNEP, 2007b).…”
