Dust particle
Dust is a mixture of tiny solid particles from sources such as soil, fibres, skin and pollen.

What are they, and what does the difference actually look like?
Two things. One honest scale.

Dust is a mixture of tiny solid particles from sources such as soil, fibres, skin and pollen.
10 µmCharacteristic size
A pollen grain carries the male reproductive cells of a seed-producing plant.
30 µmCharacteristic sizePollen grain has about 3 times the characteristic size of Dust particle.
A chosen 10 µm particle. Dust is a mixture, not a single size or material.
University of Utah — Cell size and scale
The marked characteristic size is calibrated. Unmeasured illustration details are representative.
A chosen 30 µm pollen grain. Plant species produce very different grains.
