Air Data - Page 5

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.

This dataset relates to the "Seasonality of PM10 exceedances" measure on the Environmental Indicators, Te taiao Aotearoa website.

Column headings:
- Con_mcg_m3 = Concentration in micrograms per cubic metre (μg/m3)
- In_indicat = included in analyses (1= yes, 0 = no)

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

Total suspended particulates (TSP) consist of all solid particles and liquid droplets up to 100 micrometres (μm) in diameter (ie when compared with PM10 and PM2.5, TSP is the equivalent of PM100).

TSP 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 TSP include sea salt, dust, pollen, smoke (from bush fires), and volcanic ash. TSP also forms from reactions between gases or between gases and other particles.

The smaller components of TSP (PM10 and PM2.5) are associated with health effects ranging from respiratory irritation to some forms of cancer. Reporting on changes in TSP concentrations helps us understand long-term changes in particulate matter pollution.

Column heading:
- No_exceed = number of exceedances

PM2.5 are particles 2.5 micrometres or less in diameter. PM2.5 is emitted from the combustion of fuels, such as wood and coal (eg from home heating and industry), and petrol and diesel (eg from vehicles). Natural sources have less influence on PM2.5 concentrations than PM10 concentrations. This means PM2.5 comes mainly from human activities. Nationally, burning wood or coal for home heating is the main source of PM2.5.

PM2.5 is a component of PM10 and is associated with similar health effects, ranging from respiratory irritation to some forms of cancer. However, the smaller PM2.5 particles are more closely associated with severe health problems.
