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.

This dataset relates to the "Nitrogen dioxide concentrations" measure on the Environmental Indicators, Te taiao Aotearoa website.

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.

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

This dataset relates to the "Annual average PM10 concentrations in OECD countries (urban areas)" 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.

Column headings:
- No_airsheds = number of airsheds

Sulphur dioxide (SO2) is a gas produced from human (eg industry and shipping) and natural (geothermal and volcanic) activities. Nationally, the main human-made source of sulphur oxides emissions is industry. SO2 is associated with respiratory problems, such as bronchitis, and can aggravate the symptoms of asthma and chronic lung disease.

Land use that results in a change from indigenous to exotic cover can cause biodiversity loss and reduce functioning of ecosystems. Using more land for agriculture, forestry, and urbanisation is the main driver reducing indigenous land cover across New Zealand.

Eight indigenous tree species, spanning a range of ecological niches, were surveyed twice (between 2002 and 2014) as part of a vegetation monitoring programme. The data from these surveys can be used to assess changes in tree populations. Monitoring the status and trends of these widespread tree species helps us detect large-scale, long-term changes and problems for our forest ecosystems.
