factors for Anthraquinone were estimated in GLP study Bioconcentration
and elimination of 14C residues by Eastern oysters (Crassostrea
virginica) exposed to Anthraquinone according to EPA OTS 797.1830
(Oyster Bioconcentration Test) (Fackler, P. H., 1989).
concentration of 14C-residues in the tissue of oysters
exposed to Anthraquinone at both treatment level, reached steady state
by day 1 of the exposure period. The mean (95% confidence interval)
steady-state bioconcentration factor (BCF) for 14C-residues
in the tissues of oyster exposed to 7.1 and 0.78 µg/L Anthraquinone (Day
1 -17) were 140X (90X - 190X) and 110X (94X - 130X) respectively. Model
calculation based on mean measured concentration of 7.1 and 0.78 µg/L
Anthraquinone in the test solutions and corresponding concentration of 14C-residues
in the tissue of the exposed oysters predict a bioconcentration factor
for Anthraquinone in oysters tissue was independent of the exposure
elimination of 14C-residues from oysters, after exposure to
both 7.1 and 0.78 µg/L Anthraquinone, was observed throughout the
depuration period. Half-life (50% elimination) of the 14C
residues present in the oysters tissue during steady state (exposure
days 1 -14) occur during the first 24 hours of the depuration period.
After 14 days depuration, 93% and 87% elimination of 14C
-residues present during steady-state had been achieved in oysters
exposed to 7.1 and 0.78 µg/L Anthraquinone respectively.
