"This dataset shows estimated annual emissions for different pollutants (tonnes per square kilometre): Particulate matter 10 micrometres or less in diameter (PM10); Particulate matter 2.5 micrometres or less in diameter (PM2.5); Sulphur dioxide; Sulphur Oxides (SOx); Carbon Monoxide (CO), and; Nitrogen Oxides (NOx).

Measures of:
- PM10 and PM2.5 are from home heating
- SOx are from Industrial sources
- CO and NOx are from road motor vehicles.

Data for PM10 (PM10_t_km_yr_) and PM2.5 (PM25_t_km_yr_) are provided for 2006 and 2013, including percent difference (PM10_PC_difference) and (PM25_PC_difference).

Data for CO (MV_CO_t_km_yr_) and NOx (MV_NOx_t_km_yr_) are provided for 2001 and 2013, include percent difference (MV_CO_PC_diff_01_13) and NOx (MV_NOx_PC_diff_01_13).

Data for SOx is for 2013 only (I_SOx_t_km_yr_2013).

Data is broken down by territorial authority area.

This dataset relates to various Environmental measurse on the Environmental Indicators, Te taiao Aotearoa website: home heating; road motor vehicle emissions, and industrial emissions.

Geometry: Polygons

Units: t/km/yr"

"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 PM10 includes 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.

This dataset shows annual average PM10 concentrations for years 2006 to 2013. Field names are PM10_.
This dataset also shows describes whether the PM10 trend, ie, whether concentrations have shown statisticsally significantly increases, decreases, or an indeterminate trend.

Data is broken down by monitoring site.

This dataset relates to the ""Annual average PM10 concentrations in towns and cities"" 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. The main sources are burning wood or coal for home heating, and sea spray. PM10 is of particular concern because it is found in high concentrations in some areas. It can damage health and is associated with effects ranging from respiratory irritation to some forms of cancer.

This dataset records the number of times that concentrations of PM10 exceed the daily standard for years 2006 to 2013. Field names are Yr_.

Data is broken down by airshed.

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