2-ethylanthraquinone

Particle size distribution (Granulometry)

Link to relevant study record(s)

Reference

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%.

Description of key information

The percentage of particles with a diameter lower than 100 µm was determined to be 2.674% (w/w). 

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%.
