How do you tell one dust from another?

This is what Karcher, the industrial dust extraction experts, are saying:

Construction dust is a general term used to describe the types of dusts typically encountered when working in the construction industry. As well as being a nuisance, when not correctly controlled, these dusts can seriously affect your breathing, damage your health, and with prolonged exposure some types can cause life-changing lung diseases and even kill.

We are all familiar with the day-to-day fine dust particles found in the atmosphere, such as: human skin cells, textile fibres and even burnt meteorite particles, however workers in the construction trade are faced with layers of more extreme varieties of dust.
