| Abstract | The ASTM method for measuring the bioconcentration factor (BCF) of chemicals was evaluated using 1,2,4-trichlorobenzene (TCB), hexachlorobenzene (HCB), and p,p'-DDE (DDE). Four replicate, 28-day exposures of the chemicals to fathead minnows were used to determine the precision of the test method. Using the 28-day values, the mean BCF for TCB, HCB, and DDE were 1,700 (+ or - 70), 35,000 (+ or - 3,300), and 50,000 (+ or - 4,800), respectively. The results showed that steady-state residues are not attained for highly bioaccumulative chemicals in the 28-day exposure, and the calculation of the BCF by dividing the 28 day residues by the mean water concentration is inadequate. Two alternate methods of calculating the BCF are discussed. |
