 Measurement

Result 

Mass of test item transferred to sieve 

10.18g

 Mass of test item passed through sieve

2.06g

Proportion of test item <100µm 

20.2%
Conclusions:
The proportion of rhodium trihydroxide <100 μm was 20.2 %.
Executive summary:

Walker and White (2011) is a GLP compliant study following an OECD 110 screening method and is considered suitable for use as the key study for this endpoint. The proportion of rhodium trihydroxide < 100 μm is 20.2 %.
