Air pollution costs Australia between 11 and 25 billion dollars a year in health costs. And we're one of the better countries. A real sleeper health issue. The National Pollutant Inventory (http://npi.gov.au/npi-data/search-npi-data) lets you enter your own post code to see readings for your area. You can see figures for everything from your local tip, to cars, lawnmowers and wood fires. If you have a power station nearby...gulp.
