Anyone living in or visiting the Upper Hunter Valley knows that this district suffers from serious air quality health problems. These are largely caused by air pollution from open cut coal mines and power station. NSW Deportment of Environment and Heritage recognises this problem and recently installed an Upper Hunter Air Quality monitoring system. Results of the monitoring are presented on this sophisticated website in a graphical format. http://www.environment.nsw.gov.au/aqms/uhunteraqmap.htm
The site also provides in-depth documentation on air quality monitoring methods.

HEALTH ALARMS
Anyone can subscribe Air Quality Updates http://www.environment.nsw.gov.au/aqms/subscribe.htm. You will then receive alarms when the pollutant's maximum value exceeds the NSW standard.
If the 24 hour average quantity of PM!) particles exceeds 50 micrograms in 1 cubic meter you will receive a health alarm by email or SMS


HVPA AIR QUALITY ARCHIVE
The Upper Hunter Air Quality Monitoring system provides excellent data in real time and 24 hours and 7 days history. Unfortunately, this is not sufficient to establish long term trends. We have Therefore decided to create our own history archives. This involves:
  • saving last 24 hours of data for any location with health alert
  • creating a Twitter health warning post
  • saving 7 day monitoring chart twice weekly for Mt. Thorley and Bulga


GENERAL BACKGROUND
The air quality monitoring methods are described in a great detail on this page: http://www.environment.nsw.gov.au/AQMS/aboutaqi.htm#goal
Particles - PM10, PM2.5
Not only are there gaseous pollutants, there are also solid or liquid particles that may be suspended in the air and may reduce visual amenity and adversely impact health.

NSW DECC measures particles as PM10 (particles less than 10 micrometers in diameter) and PM2.5 (particles less than 2.5 micrometers in diameter) .

Examples of particles in the air include dust, smoke, plant spores, bacteria and salt. Particulate matter may be a primary pollutant, such as smoke particles, or a secondary pollutant formed from the chemical reaction of gaseous pollutants.

Human activities resulting in particulate matter in the air include mining; burning of fossil fuels; transportation; agricultural and hazard reduction burning; the use of incinerators; and the use of solid fuel for cooking and heating.

Particulate matter can be usefully classified by size. Large particles usually settle out of the air quickly while smaller particles may remain suspended for days or months. Rainfall is an important mechanism for removing particles from the air.

The size of a particle also determines its potential impact on human health. Larger particles are usually trapped in the nose and throat and swallowed. Smaller particles may reach the lungs and cause irritation there. Fine particles can be carried deep into the lungs and irritate the airways. When exposed to particle pollution, people suffering from heart disease may experience symptoms such as chest pain, and shortness of breath. Particle pollution can aggravate existing respiratory diseases such as asthma and chronic bronchitis.
