Results and discussion

Details on results:

Nitrate ion is one of the most important nitrogen-sources for aquatic organisms, especially for algae.

They use it as a primary feed-stock for they development. In fact nitrate, with other inorganic nitrogen forms and phosphorous sources is the main responsible for the eutrophication phenomena:

[...]it can stimulate or enhance the development, maintenance and proliferation of primary producers, resulting in eutrophication of aquatic ecosystems [...]

Due to this effect, no toxicity can be evaluated for nitrate ion on algae.

Applicant's summary and conclusion

Validity criteria fulfilled:

yes

Conclusions:

In water, ADN undergoes to photodegradation into nitrate. For aquatic algae nitrate is a nitrogen source for their development, so no toxicity has been reported.
