australia pollution problem (10 marks)

Pollution in Australia:
1) Poor water quality and sediment quality are the most serious pollution affecting Australia. Ballast water is a major source of Introduced Marine Pests.
2) Australia has the highest per capita level of greenhouse gas emissions in the developed world.
3) Asian pollution fuels rain in Australia. Haze produced by fires in southeast Asia was a large-scale air quality disaster.
4) Sydney, Melbourne and other large Australian cities experience days of high air pollution. Summer and autumn are usually the worst times of the year.
The cause or affect:
Heavy reliance on coal to generate electricity cause greenhouse pollution. fires in Kalimantan and Sumatra on ambient air quality was evident by July and peaked in September/October before weakening by November, when the delayed monsoonal rain extinguished the fires and improved air quality within the region. During the period, particulate matter concentrations frequently exceeded national ambient air quality standards. Monthly mean horizontal visibility at most locations in Sumatra and Kalimantan in September was below 1 km and daily maximum visibility was frequently below 100 metres. We may see carbon monoxide, sulfur dioxide...are pollutant and sources and also health effects in the chapter too.
Community education is very important solution:
Reducing air pollution, agricultural and forest management practices that do not involve burning can also reduce the release of visibility-reducing particles. Since 1986, new cars in Australia have had catalytic converters in their exhaust systems.
