Cs, Sr, ³H TRSC adult ENVIRON PHYSIO Savannah R. site, GA, USA < 1988 All turtles from the basin
complexes had elevated Thyac
readings (mean=7598 counts/min)
whereas no control animals
registered above background.
Aquatic turtles inhabiting seepage
basins had significantly greater
variation in DNA content in blood
cells.

cypermethrin RACL adult; 2nd PESTAPP GENOTOX PQ, CAN 1993 There was no difference between Lowcock et al. 1997
and 3rd year
potato crop treated fields and
control group in terms of genotoxic
effects (chromosomal
fragmentation and abnormal DNA
profiles).
cypermethrin RACL juvenile PESTAPP GENOTOX PQ, CAN 1993 There was no difference between
potato crop treated fields and
control group in terms of genotoxic
effects (chromosomal
fragmentation and abnormal DNA
profiles). Juveniles showed physical
deformities and illnesses.
