Abstract: 

The toxicity of three fluorides (NaF, KF and FCH2COONa, respectively) on the earthworm Eisenia fetida andrei was examined using a contact filter paper test and an artificial soil test. In the contact test, NaF was found to be the most toxic compound. Toxicity decreased in the order: NaF > KF much greater than FCH2COONa. In the artificial soil test however, the toxicity from most to least toxic fluoride decreased in the order: FCH2COONa much greater than KF much greater than NaF. Apparently, both methods evaluate different mechanisms of toxification.

In the artificial soil test, the earthworms showed a decreasing body weight with increasing contents of NaF or FCH2COONa in the substrate. Fluoride accumulation increased significantly with increasing fluoride content in substrate with all fluorides tested.
