dieldrin RAPI tadpoles IMMER DEVOBS 22 0.0008- 0.6 µg/g (bioconc. factor= 690 ±190) at 0.0008 mg/L and 0.8 Schuytema et al. 1991
0.0021 mg/L µg/g (bioconc. factor= 390 ±40) at 0.0021 mg/L.
dieldrin RAPI tadpoles IMMER MORT < 0.0001- Mortality increased with conc. and time: 52.5% at 0.0101 Schuytema et al. 1991
0.0261 mg/L mg/L, 100% at 0.0261 mg/L. Survivors at higher conc. were
larger than controls.
dieldrin RATE adult TISPREP PHYSIO 10 -5 - 10 -4 M No sig. effect on frequency and amplitude of end-plate
potentials, or on end-plate membrane potential.

dieldrin RATE tadpoles IMMER RESIDUE 0.0008- 0.5 0.17 - 42.9 ppm (24-48h).

dieldrin RATE tadpoles IMMER BEHAV 0.02- 0.5 0.5 produced 5 % mortality and abnormal behaviour after 24
h, 47% mortality after 48 h. Snout abnormalities noted. 0.02
ppm had no effect.

dieldrin TRSC adult INJECT RESIDUE 28 20 Rate of absorption in tissue after injection was slow and
erratic; Residues: Body fat 445-1329 > Liver 46-117 >
Kidney 13-59 > Brain 8-27 > Muscle 4-7 > Plasma 3-7.
Values are ranges in tissue after 70d.

dieldrin XELA adult IMMER PHYSIO 1 Dieldrin treated frogs showed sig. levels of vitellogenin
induction.

dieldrin XELA adult TISPREP PHYSIO Increase in amplitude of negative after-potential; slowing of
falling phase of action potential; no effect on resting
potential; no repetitive activity.
