Description of key information

The MMAD (Mass Median Aerodynamic Diameter < 100 ¿m) has a value for the substance of 3.84 ¿m as spherical particles.

Additional information

According to OECD guideline 110, method B, the particle size distribution of the substance was determined by scanning electron microscopy method for the sieved fraction (< 100 ¿m, 14.22 % of total sample) and presented on the basis of calculated mass fractions. The median diameter was 3.84 ¿m with two main fractions of 26.31 and 70.93 % distributing in the range of 4 -10 µm and 10 - 100 ¿m, respectively.
