  • Stakeholder feedback on farm biodiversity tool

    Manaaki Whenua – Landcare Research
    This dataset supports a journal article evaluating New Zealand stakeholder perspectives on: (a) sharing farm biodiversity data; (b) behavioural factors likely to influence farmer uptake and use of a farm-level sustainability assessment tool developed for New Zealand farms; and (c) how to improve the tool. It was derived from a participatory action...

  • Nitrogen dioxide annual trends, 2011-2020

    Ministry for the Environment
    Nitrogen dioxide (NO2) is a gas that is harmful to human health (United States Environmental Protection Agency (US EPA), 2021), 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...

  • Sulphur dioxide seasonal trends, 2011-2020

    Ministry for the Environment
    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...

  • Ground-level ozone annual trends, 2011-2020

    Ministry for the Environment
    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 heat and sunlight. It is the primary component of photochemical smog. Ozone...

  • Carbon monoxide seasonal trends, 2011-2020

    Ministry for the Environment
    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...

  • Particulate matter 2.5 seasonal trends, 2011-2020

    Ministry for the Environment
    Particulate matter (PM) comprises solid and liquid particles in the air. PM2.5 particles have a diameter less than 2.5 micrometres. They can be inhaled and deposited deep in the lungs where air-gas exchange occurs. Short- and long-term exposure to PM2.5, even at low levels, is linked to respiratory and cardiovascular disease, and increased risk of...

    Ministry for the Environment
    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. Since PM10 is small...
