Particulate matter (PM) comprises solid and liquid particles in the air. PM10 particles have a diameter less than 10 micrometres. Coarse particles (2.5–10 micrometres) can be inhaled – they generally deposit in the upper airways; fine particles (smaller than 2.5 micrometres) can deposit deep in the lungs where air-gas exchange occurs. Children, the elderly, and people with existing heart or lung issues have a higher risk of health problems from exposure to PM10. These problems include decreased lung function, heart attack, and mortality.
Human-generated PM10 sources include burning wood and coal for home heating, and traffic emissions (eg combustion, tyre and brake wear, and pavement breakdown). Natural sources include sea salt, dust, pollen, and mould spores.

PM2.5 is made up of solid and liquid particles in the air with a diameter of less than 2.5 micrometres. In New Zealand, most PM2.5 in the air results from combustion (burning wood for home heating, motor-vehicle exhaust), and to a lesser extent, particles formed from reactions in the atmosphere (secondary PM) and naturally occurring sea salt.
Short- and long-term exposure to PM2.5, even at low levels, is linked to respiratory and cardiovascular disease, and increased risk of premature death, especially in vulnerable people (the young, the elderly, and people with respiratory illness). Emerging evidence points to possible links with cognitive function, neuro-development, and diabetes.

Sulphur dioxide (SO2) is a highly reactive gas formed when fuels containing sulphur, such as coal or petrochemical products (including high-sulphur ship fuel), are burned. It is also produced from industrial processes such as superphosphate fertiliser production and smelting sulphur-containing metal ores. Geothermal and volcanic gases are the main natural sources of sulphur dioxide.
When inhaled, sulphur dioxide is associated with respiratory problems such as bronchitis. It can aggravate the symptoms of asthma and chronic lung disease and cause irritation to eyes. On days with higher sulphur dioxide levels, hospital admissions for cardiac disease and mortality increase. In ecosystems, it can injure vegetation, acidify water and soil, and affect biodiversity.

Total suspended particulate matter (TSP) consists of solid and liquid airborne particles that are smaller than 100 micrometres in diameter. Although, by weight, it is dominated by the larger particles it does also include the PM10 and PM2.5 sub-fractions that are responsible for most health effects, such as respiratory and cardiovascular disease, and some cancers. TSP can be emitted from earthworks, construction and roadworks, and the combustion of fuels such as wood and coal (eg, from home heating and industry), and petrol and diesel (from vehicles).
Natural TSP sources include sea salt, dust, pollen, smoke (from bush fires), and volcanic ash.
TSP consists of airborne particles up to 100 micrometres (μm) in diameter (PM100). TSP is small enough to be inhaled; however, larger particles (10–100μm) are filtered out in the nasal cavity and are often relatively harmless.
TSP can be emitted from earthworks, construction, and roadworks, and from combustion of fuels, such as wood and coal (eg, home heating and industry), and petrol and diesel (from vehicles). Natural sources of TSP include sea salt, dust, pollen, smoke (from bush fires), and volcanic ash. TSP also forms from reactions in the atmosphere between gases or between gases and other particles.
