Description of key information

In vitro bioavailability studies in artificial body fluids were conducted with aluminium nitride.

Key value for chemical safety assessment

Bioaccumulation potential:
low bioaccumulation potential

Additional information

The solubility of aluminium nitride was determined in artificial body fluids (gastric fluid, interstitial fluid, lysosomal fluid and artificial perspiration). Results were reported as µg Aluminium/g Sample and % Aluminium release/Aluminium content.

The bioavailability ranged from 0.05 % (2 h, artificial perspiration) to 9.92 % (24 h, gastric fluid). Based on the results, the bioavailability of aluminium nitride would be expected to be low for all body fluids.
