Description of key information

For this endpoint a waiver is proposed, and a supporting  study (Sterner, 1993) although Klimisch 3 scored, is presented.

Key value for chemical safety assessment

Additional information

There is an adequate data set for mammalian toxicity and no indication from the chemical safety report to suggest that testing would be required. No study is proposed for phosphoric acid.

In the supporting study (Sterner, 1993) in which rock doves are exposed for 2 days via inhalation to phosphoric acid aerosols, no evidence of systemic effects were provided. The available data implies that the observed nutrient depletion/fluid loss are due to acid aerosol-induced ulcerations of soft tissue, although the presence of ulcers/edema is unconfirmed. Another explanation for the consumatory behaviour is the stress caused by handling and chamber confinement of the doves.
