ENANTIOSELECTIVE CHRONIC TOXICITY OF FIPRONIL TO CERIODAPHNIA DUBIA
WILSON, W. A., B. J. KONWICK, A. W. GARRISON, J. K. AVANTS, AND M. C. BLACK. ENANTIOSELECTIVE CHRONIC TOXICITY OF FIPRONIL TO CERIODAPHNIA DUBIA. ARCHIVES OF ENVIRONMENTAL CONTAMINATION AND TOXICOLOGY. Springer, New York, NY, 54(1):36-43, (2008).
To determine the environmental occurrences, fate, and effects of the enantiomers of selected chiral pesticides and other chiral pollutants.
Fipronil is a phenylpyrazole pesticide that has greatly increased in popularity in recent years. As a chiral molecule, fipronil is released into the environment as a 1:1 mixture (called a racemate) of its two enantiomers. Previous toxicity work has indicated that the enantiomers of fipronil exhibit significantly different levels of acute toxicity to the non-target organism Ceriodaphnia dubia. In this work, we examine the chronic effects of the pure enantiomers and racemate on the survival, development, mobility, and reproduction of C. dubia adults, and the survival and mobility of their offspring.
