Description of key information

Additional information

No terrestrial toxicity studies have been performed on ammonium polyphosphate for the following reasons:

Ammonium polyphosphate will ultimately breakdown to give phosphate and ammonium ions (as detailed in section 5.1 and 5.2 of this dossier). Both phosphate and ammonium are ubiquitous in the environment and are found naturally in soil, water and sediment. Ammonium polyphosphate will dissociate to the ionised ammnium ion (NH4 +) which is not considered to be toxic in the environment.

Ammonia is not expected to adsorb to soil particulate matter, suspended solids or sediment. Although ammonia is assimilated by aquatic plants for use as a nitrogen source, its bioaccumulation in biota is not important. It is therefore unlikely that inorganic phosphates of this nature would have a detrimental effect on soil microorganisms and hence toxicity studies are scientifically unjustified.
