The present findings are significant in the perspective of
amphibian population decline. Arsenic may cause reductions in
fecundity or viability, or increased mortality and lead to a reduction in the number of breeding adults. The study also has significant methodological implications. It is evident from the present
study that for single concentration genotoxicity assessment in tadpoles, 48 h exposure period may produce optimal results relative
to the 24 h exposure period considered for mammalian studies.
