Saharan Dust Particle Size And Concentration Distribution ...

The overall dust mean particle diameter, analyzed from the peak representative Harmattan periods over the 13-year period, ranged from 0.89 μm to 2.43 μm with an average of 1.5 μm ± 0.5. The particle size distributions exhibited the typical distribution pattern for atmospheric aerosols with a coarse mode diameter situated at about 3.5 μm.

EFFECT OF PARTICLE SIZE ON STABILITY OF SUSPENSION ...

Particle size of the active agent plays a key role in the physical stability and bioavailability of the drug product. The rate of sedimentation, agglomeration, is affected by particle size. The most efficient method of producing small particle size is dry milling. However, wet milling may be desirable for potentially explosive ingredients.
