EC number: 267-051-0
CAS number: 67774-74-7
Steady state concentration was reached by 48
hrs. Tissues concentrations at 96 hrs were 115 µg/g
in the gall bladder, 7.1 µg/g in
the viscera, and 1.3 µg/g in the
remainder of the fish.
This study examined the bioaccumulation of
linear alkylbenzenes in fish. 150 bluegill fish were exposed to 0.092
mg/L solution of test substance for 96 hrs (flow-through test). 3 fish
were taken for sampling at 2, 4, 8, 12, 24, 48, 72, and 96 hrs after
start of exposure. A steady state concentration in fish was reached at
48 hrs. Samples were analyzed using liquid scintillation counting.
During the depuration phase, the fish were sampled at 2, 4, 8, 24, 48,
72, and 96 hrs. An additional 150 fish were exposed to vehicle (acetone)
only. The bioaccumulation factor in fish was 35.
The BCF was 35. The bioconcentration factor in fish was determined using the ASTM E-35.21 guideline.
The study examined the bioaccumualion of the
substance in fish. A total of 150 bluegill sunfish were exposed to 0.092
mg/L substance for 96 hours in a flow through apparatus. Three fish were
sampled at several points during the study and analyzed for the
substance in the tissues. A steady state concentration was reached at 48
hours and additional fish were sampled during a depuration period.
