Description of key information

Additional information

The environmental fate endpoints are all waived. Due to its inorganic nature, the adsorption/desorption screening test cannot be conducted, while QSARs are not applicable for these kind of substances. Also biodegradation tests are not applicable to inorganics.

Due to its high solubility in water, phosphoric acid will be dissociated into its ions (H+and mainly H2PO4- and HPO42-) at pH 3, 7 and 10. In water the H+ions will form H3O+ions. The hydrolysis endpoint can thus be waived. Bioaccumulation is not relevant for such highly soluble and dissociating substances.
