18 STATE OF THE ENVIRONMENT REPORT 2008 ATMOSPHERE Air Quality in metropolitan Adelaide: NO DISCERNABLE TREND with non- compliant levels of particulates at some monitoring sites. Air Quality in Port Augusta: NO DISCERNABLE TREND Air Quality in Port Pirie: NO DISCERNABLE TREND with non- compliant levels of sulfur dioxide, lead and particles in the reporting period. Air Quality in Whyalla: NO DISCERNABLE TREND Clean and Healthy Air – maintaining and improving air quality in the Adelaide airshed and regional centres in South Australia. Environmental Protection Authority Strategic Plan 2007-2010 Note: Ambient air quality data must be long-term and comparable to determine statistically valid trends. Current monitoring programs have not been in place long enough to determine such trends in all cases. While good air quality is available to the majority of South Australians, maintaining good air quality for all is vital to the development of a sustainable state. Trends Goal Air Quality and a sustainable South Australia Air Quality Poor air quality can arise through natural processes such as dust storms and anthropogenic processes such as emissions from motor vehicles, industry and wood heaters. As it is impossible to control all of the natural processes that can cause poor air quality, it is important to have a good understanding of anthropogenic sources. While it is not always noticeable, air quality has a significant impact on the lives and lifestyles of South Australians. Poor air quality can limit the capacity for people to go out and enjoy their surrounding environment and more importantly, it can have a significant impact on the health of susceptible individuals. Elevated concentrations of air pollutants, especially particulates and ozone are known to have a negative effect on the respiratory and cardiovascular systems leading to increased illness and with particulates, increased mortality. A study into the health costs of particulate matter by the University of Adelaide and Department of Health (DoH) is underway and unavailable for reference at the time of publishing but the cost as extrapolated from New South Wales data, is estimated to be hundreds of millions of dollars (DEC, 2005). This strains the health system and ultimately also impacts other government services. Maintaining good air quality will improve public health as well as contribute to a sustainable South Australia.

Notes to the above figures:

Unlike the last report, this State of the Environment Report compares the latest emissions data to those of 1990, as that is the relevant reference year in international climate discussions. 1990 was the base year for the Kyoto Protocol and also the South Australian Climate Change and Greenhouse Emissions Reduction Act 2007.

The figures include offset for reduction in net emissions from the emissions category known as land use, land use change and forestry (LULUCF). If LULUCF is excluded from the figures, South Australia’s net greenhouse gas emissions have risen by around 11% since 1990. This trend in net emissions has been due to a substantial increase in emissions sinks balancing a similar increase in emissions sources.

LULUCF went from being a 1.6 million tonne emissions source in 1990 to a 3.6 million tonne emissions sink in 2001 and a 4.1 million tonne sink in 2006 (Department of Climate Change, 2006). Sinks have a finite capacity to offset emissions.

The data does however include net emissions from interstate electricity transfers (adding 0.6 million tonnes in 1990 and 3.2 million tonnes in 2006) and are rounded to two significant figures.

Note: Due to representation of numbers some change is realised outside of the decima places presented and is reported as such. Explanation of sectors: Stationary Energy – emissions from fossil fuel combustion for non transport energy use, for the generation of

electricity, heat production and by industry. Includes fugitive emissions from oil and gas production; Transport – emissions from the use of petrol, LPG and diesel; Agriculture – mainly the release of methane from the digestive processes of livestock and nitrous oxide emissions from soil management practices associated with crop production; Industrial processes – direct emissions generated by

chemical reactions from a range of production processes, including the production of cement, iron and steel. Solid and Liquid Waste– mainly emissions of methane from the anaerobic decomposition of organic waste in landfills and the management of sewage; Land

Use, Land Use Change and Forestry (LULUCF) – the net effect of removals of carbon dioxide by growing plants and emissions from deforestation for cropping and grazing purposes
