Quezon City MAP AIR QUALITY ANALYSIS AND STATISTICS

Is there a lot of interesting information on the air pollution map for Quezon City?

The air pollution map for Quezon City can easily be found on the main city page. At the top of this page will be the map box. When selected, the map will open a new page which is dedicated to the air quality in and around the city.

When first opened, the viewer will see several coloured discs set against a coloured map background. This overall colouration is a direct reflection of the air quality. The green colour indicates “Good” quality air. The significance of all the available colours can be seen in the legend at the foot of the page. Colours range from pale green to dark maroon and the darker the colour, the worse the air quality.

The viewer will also see many coloured circles spread across the map. These represent the location of the ground-level air monitoring stations. They each display a number which is the United States Air Quality Index reading or US AQI for short. This reading is calculated by taking the level of six of the most commonly found pollutants in the city air. Most often they are both sizes of Particulate Matter (PM2.5 and PM10), nitrogen dioxide, sulphur dioxide, ozone and carbon monoxide. When the figure is calculated it is used as a metric when comparing the quality of air in different cities around the world. It is fully endorsed by the World Health Organisation (WHO). If any area of the city is of special interest, by selecting a disc, a new page will open which gives all information about the air quality surrounding that station.

After briefly consulting the main city page again, it can be seen that Quezon City was enjoying a period of “Good” quality air with a US AQI reading of 25. The main pollutant was PM2.5 with a recorded level of 6 µg/m³. At this level, it is only just above the target figure of 5 µg/m³.

Looking immediately below the air pollution map for Quezon City can be seen the number of stations there are that provide the data for air quality and also the number of contributors who operate them. Currently, there are two contributors who operate five stations between them. One contributor is from the government while the other is from the corporate sector.

Below this information is a table showing where the most polluted stations are and their level of pollution. Currently, the most polluted area of Quezon City is around the station at the National Children's Hospital where a US AQI reading of 82 was registered. This would be classified as being “Moderate” air quality.

Following on from there, the next table shows the most popular stations which have the most followers. The most popular station is at Unioil Katipunan with more than 6,200 followers.

Is there much more interesting information about air quality on the air pollution map for Quezon City?

The air pollution map for Quezon City needs to be viewed at the full-screen level in order for all the extra information to be seen. The icon to expand the map can be selected from the top right-hand corner of the screen.

When viewed in this way, a list of four options will appear down the far left-hand side of the page. These can all be disabled individually to get a clearer picture of what each option does and how it affects the map.

The first option reveals the location of all the monitoring stations in the area, some are within the Quezon City area but others are over adjacent areas. If they appear to be on top of each other by slowly expanding the map will make the discs separate and therefore become clearer to see where they are.

The second option shows the position of any wildfires burning in the vicinity. During October 2022, there were no such icons on the map and everything seemed to be under control. If fires were detected, option four needs to be consulted because it shows the speed and direction of the prevailing winds and might help decide where the ensuing will blow to.

The third option is very theatrical as it can alter the background colour of the map to reflect current air quality. It is currently a pale green colour which does equate to “Good” air quality. If some viewers find the colour confusing it can be turned off and the map will revert to a more standard set of colours.

Some more information can be seen on the far right of the screen in the form of a table which ranks world cities according to their level of air pollution.

Can the source of this air pollution be seen on the air quality map for Quezon City?

Whilst the source of polluted air is not directly shown on the air pollution map for Quezon City, it has been established that 69 per cent of the pollutant PM2.5 comes from the emissions created by the transportation sector. In line with a policy created by the authorities in Metro Manila known as the “Anti-Smoke Belching Program”, Quezon City is conducting daily testing of random vehicles to determine their emissions. It was discovered that a mere seven per cent of all vehicles tested gave off emissions within the target figures. The remaining 93 per cent were advised to have their vehicles serviced as soon as possible.

PM2.5 is used as a benchmark on the air pollution map for Quezon City, but what is it?

PM2.5 refers to particulate matter (PM). PM2.5 is a very small air pollutant, about 2.5 microns (micrometres). The diameter of these particles is smaller than 3 per cent of the diameter of a human hair. It is a term used to describe a mixture of solid and liquid particles which are found in the air. The forms of these particles are dust, dirt, soot and smoke.

PM2.5 is formed in the atmosphere due to chemical reactions such as sulphur dioxide and nitrogen oxides. These pollutants are formed from the emissions from power plants, industry and vehicles. PM is also emitted directly from fields, chimneys, and the wear and tear of the surface of asphalt roads due to abrasion from tyres.

PM2.5 can settle on the surface and enter the deep parts of the lungs. While PM10 settles in the larger airways in the lungs. Both of these pollutants can cause tissue damage and lung inflammation.
