Let an agent explain dust and its kinds, relay sources, health and environmental effects from air quality and occupational health sources, describe control and cleaning practices in general terms, and distinguish dust from smoke, ash, aerosol as a general class and the Hanana ritual sense listed as an alias.

Research draft, second pass

A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description

Let an agent explain dust and its kinds, relay sources, health and environmental effects from air quality and occupational health sources, describe control and cleaning practices in general terms, and distinguish dust from smoke, ash, aerosol as a general class and the Hanana ritual sense listed as an alias.

Fine solid particles suspended in air or settled on surfaces, from household dust of skin flakes, fibres and soil to wood dust, marble and other mineral dusts from cutting and grinding, desert dust carried across oceans by storms, volcanic and impact ejecta, and cosmic dust; dust affects air quality, health, climate and machinery, and some dusts are regulated as occupational hazards or explosive.

What it is for: Not applicable; particulate matter.

It can be explain kinds and sources; relay health and environmental effects; describe control practices; distinguish related terms.

Distinguishing features

Fine particles

Many sources

Health hazard

Long-range transport

What it looks like

Fine grey or brown particles in air or on surfaces.

Physical character

PM10 size: under 10 micrometres

Saharan dust transported: over 100 million tonnes per year - to the Americas, estimates

wood dust classification: carcinogenic note - IARC group 1

How it is recognised

Fine solid particles

Household dust, wood dust, marble dust, desert dust, ejecta

Smoke is combustion aerosol; ash is combustion residue; the Hanana is a Bahraini ritual name that appears misfiled

What the second pass must settle

  • Should wood dust, desert dust and cosmic dust be separate primary entries?
  • How should air quality sources be linked?
  • The registry entry has a Hanana alias that appears misfiled; should it be moved?
