Administrative data
Link to relevant study record(s)
- Endpoint:
- particle size distribution (granulometry)
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 21 July 2010 to 20 January 2011
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- other: GLP study conducted in accordance with an internationally recognised method
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 110 (Particle Size Distribution / Fibre Length and Diameter Distributions)
- GLP compliance:
- yes (incl. QA statement)
- Type of method:
- other: Sieving and image analysis (microscopy)
- Type of distribution:
- mass based distribution
- Percentile:
- D50
- Remarks on result:
- other: Migrated from fields under 'Mass median diameter' as D50 percentile. No source field for Standard deviation.
- Conclusions:
- The results indicated that 0.7% w/w of MPP was smaller than 10 µm.

Description of key information
The results indicate that 0.7% w/w of MPP was smaller than 10 µm.
Additional information
The particle size distribution was determined by a combination of sieving and image analysis with combination of the results to produce a mass distribution. The results indicate that only a very small proportion of MPP is of respirable size (0.7% <10µm) and it can be expected not to present an inhalation hazard.
