Air quality readings as per the National Environment Protection Messure for PM10 and PM2.5
are daily averaged (Midnight to midnight)
There is no standard shorter than this for PM's. Health problems can result as a result of this
as explained in the Guide above.
Readings can be high for a good part of the day but if the 50mg/m3  Pm10, and 25mg/m3 
PM2.5 average is not breached then there would not be an exceedence of the NEPM
There is no Visible Reducing Index in Tasmania like in Victoria.

In the main these real-time readings cannot be used to determine if there has been an exceedance of the Ambient Air - National Environment Protection Measure. (Air NEPM).

The light scattering lazer particle counters are an equivalent measuring instrument under the current Australian NEPM Standards. They give us an almost real - time air quality reading whereas it can take several weeks to get a validated air quality reading from a gravimetric (weight of particles, not number of particles) style monitor.

Depending on pollution source, wind direction, and where fixed air monitors are positioned, it is possible there will be gaps in our air monitoring. Mobile or portable monitors are being used to 'plug some of these holes'.

Environment Minister’s Council Abolished
Australia’s environment ministers will no longer meet as a group to tackle common environmental issues.
The COAG Standing Council on Environment and Water was abolished at the council’s meeting on 13 December 2013, the first since the federal Coalition was elected. “Too much bureaucracy and red tape has grown up around COAG,” the meeting communiqué said. COAG decided 22 standing committees “should be streamlined and refocused on COAG’s priorities over the next 12-18 months”. Of the eight new committees none will deal with environment, water or climate change issues.

NEPMs in Tasmania
In Tasmania, NEPMs are State Policies in accordance with section 12A of the
State Policies and Projects Act 1993. They are generally not directly
enforceable and are implemented using a variety of mechanisms and
approaches depending on the particular contents of each NEPM.

Information on how each of the NEPMs is being implemented in Tasmania can
be found in
NEPC annual reports.

This is a must watch video . New Smoke Forecasting System….for  Australia, for Tasmania.

AFAC's Predictive Services Systems Working Group sponsored a webinar on 19 December to demonstrate the Bureau of Meteorology’s new Smoke and Air Quality Forecasting System (AQFx) modelling application for forecasting smoke and air quality….in Tasmania.

Published on Jan 7, 2018:

I asked BoM is it being used in Tas.

This was their reply:
“We are currently using the AQFx system internally to predict smoke travel in Tasmania.
As this is still an experimental system, the results are not available to the general public. Some emergency management and land management agencies are able to see the smoke forecasts via a registered user page.

The system can predict smoke from planned burns prior to the burn taking place as well as smoke from existing planned burns or wild fires. The facility to predict smoke from planned burns depends on getting information on these burns from other agencies, and this may not currently be implemented in all jurisdictions.”

So now I ask the question again.
If we have the means to PREDICT smoke travel before (and after) a deliberate outdoor burn, why are people being forced to breathe this toxic smoke?

Calls for air quality monitoring as northern NSW braces for severe bushfire season
More than 500,000 people live between Tweed Heads and Newcastle.
None of the State Government's network of 85 permanent air monitors are located between Tweed Heads and Newcastle.
Now, DPIE's director of climate and atmospheric science, Matthew Riley, said establishing a station on the North Coast was
a priority because of its significant population growth.
The DPIE would "undoubtedly" be monitoring on the North Coast
within the next five years, he added.
A pair of 16ft lungs made from steel, wood and fibreglass were installed beside City Hall today to help visualise the impact of pollution on Londoners’ breathing.
84% of Londoners surveyed were worried about health risks from toxic particles in their airways.
The lungs are filled with different colours of smoke to represent levels of different pollutants inhaled in the capital every day.
Have a look at THIS PAGE trying to describe the Air Quality Index (AQI) used in the US for example.
No wonder people are confused with ambient air quality readings.
Why make it so complicated using formulas and colours and numbers that go up to 500!
Give us the raw PM2.5/PM10 data straight off the instruments.
And HERE is someone else trying to explain AQI, or is it API, or maybe it is PSI??
Oh my goodness and it works out different in different countries!!
Get a load of this explanation.  We don't have to put up with this....
The Air Quality Index (AQI) (also known as the Air Pollution Index (API) or Pollutant Standard Index (PSI)!! is a number used by government agencies to characterize the quality of the air at a given location. As the AQI increases, an increasingly large percentage of the population is likely to experience increasingly severe adverse health effects. To compute the AQI requires an air pollutant concentration from a monitor or model. The function used to convert from air pollutant concentration to AQI varies by pollutant, and is different in different countries. Air quality index values are divided into ranges, and each range is assiged a descriptor and a color code. Standardized public health advisories are associated with each AQI range.
What a mouthful. Totally unnecessary.

COMMENTS: Closed early so here it is....
Can't believe there are no air monitoring stations in or around Bendigo Victoria! Surely Vic EPA learnt something from the Hazelwood coal mine fire?  This is so bad and people shouldn't have to put up with that!
Professor Bin Jalaludin, from experience I disrespectfully disagree with you when you say, " the end it may be decided that maybe this [24-hour rolling average] is the best way." This just seems a cop out, we have advanced far beyond that standard. People shouldn't have to wait 24 hours to see what the air quality ...was.
As one of the many asthmatics living in Tasmania where we have the best EPA air monitoring network in Australia I think it is time other states caught up. If we can do it then you owe this health service to your people.
We have real-time ambient air quality monitoring (every 10 minutes) posted on the web at
We also have a stacked plot where it is easy to track smoke travel. If you want to see how it works go here:
A DHHS air advisory alert for sensitive people is enacted on our Health web site when the hour-average PM2.5 value is above 25 µg m-3.
I am sorry but you people on the big island seem to be asleep when it comes to protecting your respiratory health. Demand better from your agencies.

Can This Cheap, DIY Air Pollution Sensor Help the World Get Clean Air?Columbian citizen scientists built dirt-cheap air quality monitors and deployed them across their city, forcing the government to confront its pollution. Now they’re teaching others to build them, too.
Low-Cost Home Air Quality Monitors Prove Useful for Wildfire Smoke
Published recently in the journal Sensors, their study tested four models of low-cost air quality monitors during actual wildfire pollution events and found that their readings of PM2.5 – or particulate matter under 2.5 microns, which has been linked to respiratory and cardiovascular issues – were consistently higher than the reference monitor used by the regulatory agencies; however, since each monitor had a relatively consistent response to the smoke, it is possible to use the readings to estimate true PM2.5 levels. Overall, the researchers concluded that the monitors can provide actionable information.
Microplastics are contaminating our air
Microplastics from the ocean are being transported in the wind and are polluting our air.
The researchers have highlighted that this 11% from sea spray is particularly alarming.
Having analysed where this pollution came from, the researchers found that oceanic action grinds plastic waste in the ocean into micron-size particles, where the wind then transports them into the atmosphere.
Commercial aircraft continue to fly, with no contaminated air warning systems to inform passengers and crews when the air they are breathing is contaminated.
Captain Tristan says the air onboard passenger planes is contaminated because of ‘bleed air’, which brings air in through the compression section of the engines, or from the auxiliary power unit, a small engine at the tail of the aircraft. He says it is not filtered and has been known to be contaminated with jet engine oils and other fluids.
A new air pollution calculator will provide individuals worldwide with real-time exposure data.
The calculator, which has been developed with support from the United Nations Sustainable Development Solutions Network combines global governmental, crowd-sourced and satellite pollution data.
This is then combined with population data and artificial intelligence technology to calculate – every hour – country population exposure to air

Have we been monitoring air pollution all wrong?
“In our research, we found that there was a very difficult correlation between toxicity and the number of particles, but a relatively level correlation as soon as we looked at toxicity versus surface area.”
Ken Szutu says, “When people ask me "What is a reasonable time interval to do AQI average?" My answer is "How long can you hold your breath?"
Environmental Management and Pollution Control (Smoke) Regulations
The Environmental Management and Pollution Control (Smoke) Regulations 2019, usually referred to as the Smoke Regulations, are used by local government to regulate 'domestic' wood smoke in Tasmania.
The Smoke Regulations took effect on 26 June 2019, replacing the Distributed Atmospheric Emissions Regulations 2018.

Air Monitors Alone Won't Save Communities From Toxic Industrial Air Pollution
“..monitors serve as a false promise to residents that the findings will be used to keep them safe. Some people believe the mere existence of monitoring is "protecting them" from harm, said Barbara Morin, an air pollution expert at a nonprofit that advises the environmental regulators of eight Northeastern states. "Unfortunately, sometimes there's just the monitoring and nothing happens to change the situation."
New type of extremely reactive substance in the atmosphere
An entirely new class of super-reactive chemical compounds has been discovered under atmospheric conditions. Researchers have documented the formation of so-called trioxides -- an extremely oxidizing chemical compound that likely affects both human health and our global climate.
Very few regulatory options are on the books for controlling wildfire smoke as an air pollutant since the fires are considered “exceptional events” that don’t count against a region’s compliance with National Ambient Air Quality Standards.
The EPA is paying closer attention to the health impacts of wildfire smoke, which is one of the leading sources of particulate matter, a top agency official said on Thursday.

From EPA Tasmania:
The National Environment Protection (Ambient Air Quality) Measure (known as the Air NEPM) stipulates air quality standards in Australia. For PM10 there is a 24-hour standard of 50 µg m-3 (50 millionth of a gram per cubic metre). That is, if PM10 levels measured by a reference instrument averaged over a calendar day exceed 50 µg m-3, an exceedance of the standard is recorded. The Air NEPM stipulates that the reporting interval is the calendar day (midnight to midnight). The annual standard for PM10 is 25 µg m-3, with the reporting interval being the calendar year. For PM2.5, the 24-hour (calendar day) standard is 25 µg m-3, with an annual standard of 8 µg m-3. Currently there are no NATIONAL standards for PM10 or PM2.5 for intervals shorter than 24 hours.”
AND NOW NOTE:   There are no maximum allowable exceedances.
Comparer this with the earlier 2016 Standards further up the page.

he Tasmanian Department of Health provides the following air quality HEALTH CATEGORIES based on the HOUR-AVERAGED PM2.5 value.
Good: 0 to 9 micrograms per cubic metre
Fairly Good: 10 to 24 micrograms per cubic metre
Fairly Poor: 25 to 49 micrograms per cubic metre
Poor: 50 to 99 micrograms per cubic metre
Very Poor: 100 to 299 micrograms per cubic metre?
Extremely Poor: Over 300 micrograms per cubic metre?
PM2.5 values below 5 µg m-3 signify very clear air
