Australia's Clean Air Myth

I've been thinking a lot about air quality in Australia recently as I wrote up my submission in response to Victoria's Air Quality Statement, which will help shape a future air quality strategy for this state.  The Clean Air Statement presents a rosy picture for air quality in Victoria - our air is repeatedly described as "great" and "very good" - and this leaves the impression that air pollution is not a current health danger to Victorians.  Anecdotally, I have seen this attitude adopted by Australians around the country, who ask me why I need to research air quality in Australia and tell me that we already breathe clean air.  It is true that our air is cleaner than many of our neighbours, but this doesn't mean that it is healthy.  Air pollution in China, for instance, is one of the biggest handbrakes on development in what may soon be the world's biggest economy, and it is meaningless to compare it to Australia.

So, how big is Australia's air …

Peat Fire Burns On

I took a break from blogging for a couple of weeks over Easter, and for that entire time peat bog fires have been burning here in southwestern Victoria.

Peat fires have been smoldering at Cobrico since St Patrick's day, creating significant air pollution for almost a month now.  Vulnerable elderly residents and school students have been relocated, and a dedicated water pipeline has been constructed to help battle it.

Burning peat bogs present particularly nasty environmental problems because they are difficult to extinguish and produce highly toxic smoke.  Peat does not burn in a hot, raging fire, meaning that the fuel source can last for many months, and also that the smoke produced is heavily laden with toxic fine particulate matter and carbon monoxide; these pollutants would be more fully consumed in a hotter blaze.  Peatlands also tend to extend over large inaccessible areas, and can smolder at depths of several metres.

Peat fires present a broader global environmental proble…
