Black carbon is a particle, often in the PM2.5 or ultra-fine size range, which is emitted from combustion sources and is commonly known as soot. In New Zealand most black carbon is emitted from vehicles (especially diesel vehicles), burning wood and coal for home heating, and outdoor burning. Both long and short-term exposure to black carbon is linked to serious health effects, such as respiratory and cardiovascular disease, cancer, and premature death (World Health Organization (WHO), 2013).
Black carbon warms the climate globally and regionally because it is efficient at absorbing energy from sunlight. Black carbon also increases ice and snow melt when deposited on these surfaces, darkening them and lowering albedo (proportion of light that is reflected) so they absorb more solar energy (Ramanathan & Carmichael, 2008).

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.

Nitrogen dioxide (NO2) is a gas that is harmful to human health, ecosystems, and plants (US EPA, 2008). It can be emitted directly into the air but is often formed as a secondary pollutant when nitric oxide (NO) emissions react with other chemicals. It also contributes to the formation of secondary particulate matter (PM) and ozone, which have their own health impacts. In New Zealand, motor vehicles are the main human-made source of nitrogen oxides (NOx), the collective term for NO2 and NO. Because nitrogen dioxide concentrations are closely associated with vehicle emissions, it can be used as a proxy for other motor-vehicle pollutants such as benzene, carbon dioxide, and carbon monoxide.
Human exposure to high nitrogen dioxide concentrations causes inflammation of the airways and respiratory problems, particularly asthma. Nitrogen dioxide causes leaf injury in plants exposed to high levels. It also contributes to forming secondary particulate matter and ozone, which have their own health impacts.
We report on observed nitrogen dioxide concentrations from 13 regional council and unitary authority monitoring sites. Council and unitary authority data are measured using regulatory-compliant monitors that can be directly compared with health guidelines.

Ground-level (tropospheric) ozone (O3) exists at a natural background level but is also produced when nitrogen oxides (NOx) and volatile organic compounds from vehicle emissions, petrol fumes, industrial processes solvents, and other human-made sources react in the presence of sunlight. It is the primary component of photochemical smog.
Ozone also occurs naturally in the stratosphere, where it protects us from ultraviolet radiation – this ozone occasionally can mix downwards to ground level.
Because sunlight and warmth are required for the chemical reactions that form ground-level ozone, peak concentrations often occur in summer when daylight hours are longer and temperatures are higher. Since the precursors for ozone can travel downwind from their sources before they react with sunlight, ozone concentrations can be high many kilometres from the precursor emissions’ sources.
Exposure to high concentrations of ozone can cause respiratory health problems and is linked to cardiovascular health problems and mortality. It can also damage vegetation.

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.

The air pollutant emissions indicator reports on national human-generated (anthropogenic) emissions of particulate matter (PM10 – particles smaller than 10 micrometres and PM2.5 – the subset of PM10 particles that are smaller than 2.5 micrometres), nitrogen oxides (NOx), carbon monoxide (CO), and sulphur dioxide (SO2), between 2012 and 2019. The grouped sources include: energy (combustion), transport, construction (non-combustion), road dust, industrial (non-combustion), agriculture, biomass burning, and waste. Only human-generated emissions were included in this emission inventory.

When air pollution levels are high, they can affect human and ecosystem health. An emissions inventory provides information on the sources and quantities of key air pollutants that are released into the atmosphere. By understanding the amounts that different sources contribute, air quality can be better managed and modelled.

Carbon monoxide (CO) is a colourless, odourless and tasteless gas. The most common sources of carbon monoxide are from the incomplete combustion of fossil fuels such as fuel used by vehicles, and from wood and coal, commonly burnt in fires for home heating. Other common sources of carbon monoxide are tobacco smoke and indoor gas fires. It also occurs naturally, for example, from volcanoes and wildfires.

Carbon monoxide can affect human health by interfering with the blood’s ability to absorb and circulate oxygen and by aggravating heart conditions. It has a relatively long life in the atmosphere – about three months. This is due to the slow rate at which carbon monoxide oxidises, forming carbon dioxide (a greenhouse gas). Carbon monoxide also has an important role in forming smog.

This dataset reports on the annual trends assessed for the period 2011-2020.

Ozone is a colourless, odourless gas. Exposure to high concentrations of ozone can cause respiratory health problems and is linked to cardiovascular health problems and increased mortality. Those most at risk include people with asthma, children, older adults, and people who are active outdoors, such as outdoor workers. People with certain genetic characteristics and nutrient deficiencies are also at greater risk from ozone exposure. Ozone can also affect sensitive vegetation and ecosystems and can cause damage during the growing season.
