dieldrin BUAR embryo IMMER PHYSIO 0.02-2 mg/L Embryos developed in 0.2 and 20 mg/L died between 20 -2 5
d: 25-30% of those developed in 0.02 mg/L had front legs
earlier than controls.
dieldrin BUAR embryotadpole
IMMER RESIDUE 0.02-2.0 mg/L Behavioural abnormalities; decreased phospholipid content
and altered morphology; no effect on body weight, protein
content and enzyme activities.

dieldrin BUAR oocytes IMMER PHYSIO 4 mg/L Authors suggest that after agonist-dependent hydrolysis of Fonovich De Schroeder et al.
phosphonositides, PIP and PIP2 kinases are activated in
control but not in dieldrin-treated oocytes.

dieldrin BUAR oocytes TISPREP PHYSIO 0-50 6-10 10 -5 - 10 -12 M Phospholipase C activity interacted with dieldrin. Enhanced
degradative activity was noticed for doses from 10 -9 to 10 -7
