Nige's Diet Nutrition Blog Why (LDL particle) size matters.

If there's a 10% reduction in LDL particle size, the volume reduces to 0.729, relative to the original size. Therefore, to carry the same amount of cholesterol requires 1/0.729 = 1.37 times more particles, which is a 37% increase in the number of LDL particles, relative to the original size.

Particles found in the air we breathe vary greatly in size. The greatest health hazard from particles comes from the smallest ones less than 10 micrometres (10 m or 10 microns) across because we easily inhale these small particles into our lungs.

Understanding Particle Size Distribution Calculations HORIBA

All particle size analysis instruments provide the ability to measure and report the particle size distribution of the sample. There are very few applications where a single value is appropriate and representative. The modern particle scientist often chooses to describe the entire size distribution as opposed to just a single point on it.

Measurement of particle size distribution in suspension

Cen- trifugation is a method for particle size analysis that sepa- rates particles by the response of physical forces acted upon the particles as a function of the particle size. The minimum size obtained by centrifugation is ∼0.05mm. All three meth- ods are strongly influenced by the particle shape.
