Results and discussion

Any other information on results incl. tables

Levels of Ca in the snails from the two sites differ markedly.

Both groups showed a decline in Ca following the initial two days on the high Pb diet, though this reduction is only significant in the CP snails.

The high levels of Pb achieved in both groups without any increase of mortality indicate that the toxic metal is isolated in an innocuous form, as granules, or deposited in the shell.

Applicant's summary and conclusion

Validity criteria fulfilled:
not specified
Conclusions:
In this study, lead sulphate was not found toxic for snail. However, Pb induced a change in Calcium metabolism.
