Nitrogen dioxide (NO2) is a gas. It can be emitted directly into the air but is most often formed when nitric oxide (NO) emissions react with other chemicals in the air. Nationally, road motor vehicles are the main human-made source of nitrogen oxides (NOx, the collective term for NO2 and NO). NO2 may cause respiratory infections and reduced lung development and functioning.

Nitrogen dioxide (NO2) and nitric oxide (NO) (collectively known as nitrogen oxides, NOx) are emitted from the combustion of fossil fuels and from natural sources such as volcanoes. The four main human-made sources of key pollutants in New Zealand are burning wood or coal for home heating, road motor vehicle use, industry, and household outdoor burning.

Column headings:
- Con_mcg_m3 = Concentration in micrograms per cubic metre (μg/m3)

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.

Ozone occurs in two regions of Earth’s atmosphere – at ground level and in the upper atmosphere. Ground-level ozone is a gas formed by chemical reactions involving sunlight, volatile organic compounds, and nitrogen oxides (the main source being vehicle emissions). It is linked to increased health risks, such as respiratory and cardiovascular diseases.

Given the time required for the chemical reactions that form ozone to take place, high concentrations of it occur well away and downwind from where the pollutants are initially emitted.

Column headings:
- Con_mcg_m3 = Concentration in micrograms per cubic metre (μg/m3)

We measure the annual concentrations and proportions of natural and anthropogenic particulate matter 10 micrometres or less in diameter (PM10). PM10 in the air comprises solid particles and liquid droplets from both natural and human-made sources.

PM10 occurs naturally, for example, as sea salt, dust (airborne soil), or pollen. Airborne soil particles, although natural, are also produced by human-made processes such as construction and industrial activities. Natural particulates can make up a large portion of PM10 in some areas.

Research on the health effects of natural particulate matter is inconclusive, and the World Health Organization (WHO) considers all particulate matter of a certain size to be of equal toxicity. Natural particulates are generally in the PM2.5 to PM10 size range, which typically has less harmful health effects than smaller particles.

This dataset relates to the "Natural particulate matter 10 micrometres or less in diameter (PM10)" measure on the Environmental Indicators, Te taiao Aotearoa website.

Particulate matter 10 micrometres or less in diameter (PM10) in the air comprises solid particles and liquid droplets from both natural and human-made sources. PM10 can be emitted from the combustion of fuels, such as wood and coal (eg from home heating and industry), and petrol and diesel (from vehicles). Natural sources of PM10 include sea salt, dust, pollen, smoke (from bush fires), and volcanic ash. Nationally, burning wood or coal for home heating is the main human-made source of PM10.

PM10 is of particular concern because it is found in high concentrations in some areas and can damage health. It is associated with effects ranging from respiratory irritation to some forms of cancer.

Particulate matter 10 micrometres or less in diameter (PM10) is an air pollutant that causes health problems ranging from respiratory irritation to cancer. Reporting on the annual PM10 concentrations in Organisation for Economic Co-operation and Development (OECD) countries helps us understand the scale of PM10 pollution in New Zealand and how we rank internationally. The OECD consists of 34 countries with similar levels of economic development.

PM10 can be emitted from the combustion of fuels, such as wood and coal (eg from home heating and industry), and petrol and diesel (from vehicles). Natural sources of PM10 include sea salt, dust, pollen, smoke (from bush fires), and volcanic ash. PM10 also forms from reactions between gases or between gases and other particles.

- Con_mcg_m3 = Concentration in micrograms per cubic metre (μg/m3)
