Aliesterase- (Ali-E) activity in Daphnia magna straus as a parameter for exposure to parathion
- 26 Downloads
In vivo exposure of Daphnia magna Straus to parathion in concentrations from 0.05 to 5 µg/l resulted in a concentration-dependent decrease in aliesterase activity of the homogenate of the animals. Decrease in this activity after 48 hours of exposure was maximal for concentrations > 1.5 µg/l and amounted to about 90% of the activity of the blank.
