Composition of Coal, hopefully may enlighten why you cant just add water to put it out, but you must suffocate and drown it.
Basically it is self efficient as it is part oxygen.
Alright so this is why they are considering what to do with a population base of 13000 people.
World Health Guidelines for Air Quality & Health
http://www.who.int/mediacentre/factsheets/fs313/en/Particulate matter
Guideline values
PM2.5
10 μg/m3 annual mean
25 μg/m3 24-hour mean
PM10
20 μg/m3 annual mean
50 μg/m3 24-hour mean
The 2005 AQG set for the first time a guideline value for particulate matter (PM). The aim is to achieve the lowest concentrations possible. As no threshold for PM has been identified below which no damage to health is observed, the recommended value should represent an acceptable and achievable objective to minimize health effects in the context of local constraints, capabilities and public health priorities.
Definition and principle sources
PM affects more people than any other pollutant. The major components of PM are sulfate, nitrates, ammonia, sodium chloride, carbon, mineral dust and water. It consists of a complex mixture of solid and liquid particles of organic and inorganic substances suspended in the air. The particles are identified according to their aerodynamic diameter, as either PM10 (particles with an aerodynamic diameter smaller than 10 µm) or PM2.5 (aerodynamic diameter smaller than 2.5 µm). The latter are more dangerous since, when inhaled, they may reach the peripheral regions of the bronchioles, and interfere with gas exchange inside the lungs.
Health effects
The effects of PM on health occur at levels of exposure currently being experienced by most urban and rural populations in both developed and developing countries. Chronic exposure to particles contributes to the risk of developing cardiovascular and respiratory diseases, as well as of lung cancer. In developing countries, exposure to pollutants from indoor combustion of solid fuels on open fires or traditional stoves increases the risk of acute lower respiratory infections and associated mortality among young children; indoor air pollution from solid fuel use is also a major risk factor for chronic obstructive pulmonary disease and lung cancer among adults. The mortality in cities with high levels of pollution exceeds that observed in relatively cleaner cities by 15–20%. Even in the EU, average life expectancy is 8.6 months lower due to exposure to PM2.5 produced by human activities.
So the EPA are now monitoring,
http://www.epa.vic.gov.au/Our-work/Monitoring-the-environment/Air-quality-bulletins/Hourly-air-quality-data-tableA snapshot of the monitoring results in Morwell tonight so remembering
Guideline values
PM2.5
10 μg/m3 annual mean
25 μg/m3 24-hour mean
So WHO sets guideline @ 25 μg/m3 24-hour mean and Morwell, is currently 250+μg/m3 for the last hour....
mind you epa did not start publishing the monitoring this until 0200 on the 22/02/2014...
