Description of key information

The MMAD (Mass Median Aerodynamic Diameter < 100 μm) has a value of 3.12 μm as spherical particles.

Additional information

According to OECD guideline 110, the particle size distribution of 3-Hydroxy-2-(3-hydroxy-2-quinolinyl)-1H-inden-1-one was determined by scanning electron microscopy method for the sieved fraction (< 100 µm, 7.40% of total sample) and presented on the basis of calculated mass fractions. The median diameter was 3.12 µm with the main fraction of 67.1% distributing in the range of 4 - 10 µm; and hence the tested 3-Hydroxy-2-(3-hydroxy-2-quinolinyl)-1H-inden-1-one particles with sieved size smaller than 100 µm are dominated by thoracic fraction as defined in EN 481.
