This URL is a model of an accessible but scholarly review of factors causing
amphibian malformations.

   http://pubs.usgs.gov/fs/fs-043-01/

Briefly: Endocrine Disruptor insecticides can mimic sex hormones:
human sex hormone increases in the environment
 (associated with birth pill etc)
UVB can cause genetic damage,
Trematode (flat) worms parasitic on snails
cause mechanical disruption to amphibian growth centers;
  fertilizer runoff can  increase populations of parasites with other
populations:
low potassium & sodium in  the water can potentiate a factor mentioned
above.

About high dose challenges: I recall that investigators assaying magnetic
 field sensitivity in animals were sometimes defeated by  too high,
 or inhomogeneous test fields.
