Comments
Static 50 6 hours 10 River water mixed with
dechlorinated tap water,
pH 8.12-8.36. Fish were
exposed to TPP+water
for 6 hours then
transferred to clean
water. BCF expressed
as
k(uptake)/k(elimination).
k(uptake) = 46.36/hour.
Elimination rate slows
down at about 9 days
with 98-99% eliminated.
k(fast)=0.0179/hour;
k(slow)=0.00245/hour.

25 BCF is independent of
concentration,
continuous (flowthrough)
results correlate
to static results (Sasaki,
1981). BCF of
phosphate esters tested
correlate with Log K ow.
