Dust

Dust kicked up by farm vehicles, building sites or transport can be a nuisance.

This page provides information on sources of dust and its environmental and health effects.

Sources of dust

Airborne dust is produced from a wide variety of human activities.

These include:

wind-blown dust from exposed surfaces such as bare land and construction sites

road works

dust caused by vehicle movements along unsealed roads

housing developments

mines and quarries

agriculture and forestry activities

Large quantities of dust can also be generated from natural sources such as dry riverbeds, pollen from plants and volcanic eruptions.

Environmental and health effects of dust

Typically, the particles from dusty activities are larger than 10 micrometres in diameter, but they can still be a nuisance and affect health. Dust can irritate your eyes and make them itchy and watery, and can be a nuisance (eg, when it settles on windowsills and washing making things dirty).

Dust can also affect the health of plants. When dust settles on leaves it affects photosynthesis and the amount that plants grow.
