Industrial activities emit a range of pollutants that affect our air quality. The health effects associated with exposure to these pollutants range from respiratory irritation to some forms of cancer. Nationally, industrial activities are the main human-made source of sulphur dioxide emissions.

This dataset relates to the "Industrial emissions" measure on the Environmental Indicators, Te taiao Aotearoa website.

Lead is a heavy metal. Airborne sources include some industrial discharges, such as at metal smelters and the removal of lead-based paint from buildings without proper safety precautions. Lead can harm the nervous system and hearing, and impair mental development. Before 1996, when petrol became lead free, some New Zealand sites experienced elevated lead concentrations.

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

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.

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

This dataset relates to the "PM10 daily concentrations" measure on the Environmental Indicators, Te taiao Aotearoa website.

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.

Column headings:
area_ha = area of land cover measured in hectares
