Particle size distribution (Granulometry)
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:
- 25.11.2011 - 24.01.2012
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- other: Study was perfomed under GLP conditions according to OECD guideline
- Reason / purpose for cross-reference:
- reference to same study
- Qualifier:
- equivalent or similar to guideline
- Guideline:
- OECD Guideline 110 (Particle Size Distribution / Fibre Length and Diameter Distributions)
- Deviations:
- no
- Principles of method if other than guideline:
- The inhalable mass fraction defined as mass of particles which can be inhaled by nose or mouth was determined by absorption with 100 micrometer molecular sieve.
- GLP compliance:
- yes (incl. QA statement)
- Type of method:
- sieving
- Type of distribution:
- other: mass fraction of particle size <100nm
- Percentile:
- D50
- Remarks on result:
- other: median diameter not determined(migrated from fields under 'Mass median diameter' as D50 percentile. No source field for Standard deviation.)
- No.:
- #1
- Size:
- > 0 - < 100 µm
- Distribution:
- ca. 2.674 %
- Conclusions:
- The particle size of 2.674% (w/w) of the test item 2-ethylantraquinone was less than 100 µm.
- Executive summary:
The proportion of test item having an inhalable particle size of less than 100 µm was determined according to OECD TG 110 by a sieve method to be 2.67%.

Additional information
The proportion of test item having an inhalable particle size of less than 100 µm was determined according to OECD TG 110 by a sieve method to be 2.67%.
