摘要：

We investigated the effect of glyphosate (GLY) to Scinax nasicus tadpoles and the influence of GLY degradations in the variation of LC50 values. These results showed that 96-h LC50 for S. nasicus tadpoles exposed to continuous applications of GLY in the renewal tests (RT) was 3.13 mg GLY/L, compared to an estimated LC50 in static tests (ST) of 5.27 mg GLY/L. These data indicate large differences in toxicity between RT and ST, S. nasicus tadpoles did not die when the GLY exposure was not continuous.
