Description of key information

One key study exists. This study is considered to be acceptable for use as a key study in accordance with Regulation (EC) No. 1907/2006.

Additional information

The granulometry study shows that tricalcium bis(orthophosphate) consists of approximately 98% of particles with a particle size of <45µm (considered to be respirable). As such the particle size distribution indicates substance is an inhalation risk (a significant proportion of the particles are present at < 100 µm).
