There is a great deal of very interesting information about air quality on the air pollution map for Shahin Shahr. By selecting the air pollution map icon, a new page will open which contains all available information about the current state of the air.
When the new page opens a solid colour will meet the viewer which is a direct visualisation of the current air quality. Colours vary between pale green and dark maroon and are used as a standard across the entire IQAir site. The meaning of each colour can be seen in the legend at the foot of the page.
Currently, at the beginning of April 2023, the map is dark green/yellow which indicates the air quality as being “Moderate”. This level of quality is derived from calculating the United States Air Quality Index reading or US AQI for short. Measurements are taken of the levels of pollution caused by up to six of the most commonly found pollutants in the city air. They are usually both sizes of Particulate Matter (PM2.5 and PM10), ozone, nitrogen dioxide, sulphur dioxide and carbon monoxide.
Usually, when looking at the map, there will be several coloured discs dotted over it. These reveal the locations of the ground-level air monitoring stations which collect the data about air quality. Not all cities have these “real” stations and rely on data from overhead satellites instead. Having said that there are no stations near the city of Shahin Shahr. The US AQI reading is usually displayed at the centre of the discs which are seen dotted across the map.
Looking back to the main city page, displayed in the coloured band at the top is the current state of the air as shown by the US AQI reading. At the time of writing in April 2023, the reading was 55 which is classified as being “Moderate” air quality. The main pollutant was identified as PM2.5 with a recorded level of 14.1 µg/m³ (microns per cubic metre) which is almost three times higher than the target figure of 5 µg/m³ as recommended by the WHO. The asterisk to the right of the reading shows that the figure is derived from satellite modelling and not from physical stations.
The air pollution map for Shahin Shahr is filled with wonderful information about the air quality in the local area. At the top of the page is an icon which will open a new page in “full screen” mode so all the information can readily be seen.
Once opened in full screen mode, there will be a list of four options which appear on the left-hand side of the screen. These can each be individually deactivated to get a better idea of the effects they have on the map.
The first option would show the sites of the ground-level air monitoring stations but, as already stated, Shahin Shahr has no physical stations.
The next option shows the position of any wildfires there are that might be burning out of control in the area. At the beginning of April 2023, there were no reports of any wildfires in the vicinity. If fires are detected, then option four needs to be consulted because it shows the speed and direction of the prevailing winds and will give a good indication of where the ensuing smoke may drift.
The third option is very theatrical because it changes the background colour of the map to show the current level of air quality. When the air quality is “Moderate”, the map will take on a greenish/yellow hue to instantly show the viewer the level of pollution. If viewers find this overall colour to be too distracting, then they can deactivate it and the colour will revert to a more subtle palette.
There are more facts and figures about the world’s most polluted cities on the right-hand side of the screen. A table will be found here that ranks the top seven most polluted cities in the world. By opening the full-ranking section the rest of the participating world cities will be seen in descending order.
The source of the polluted air cannot be directly identified from the air quality map for Shahin Shahr but this city is close to major industrial centres such as refineries, power plants, petrochemicals, military industries, dairy industries and chemical plants. Mahmoud Abad Industrial Estate and dozens of large industrial complexes are in the vicinity of this city, Shahin Shahr is one of the industrial and technical hubs of Isfahan province.
Pollutants are caused by domestic and commercial activities, including fuel combustion for heating and cooking, cleaning or the use of insecticides. Although the amount of this pollution is not much compared to other sources, but this amount increases the air pollution in the urban environment.
Pollution caused by industries is caused by artificial activities. Among the industries, thermal power plants, chemical factories, cement, paper, textile, tannery, etc. are the main sources of air pollution. Applying appropriate pollution control methods will be effective in reducing the pollution of these sources.
The pollution caused by the transportation sector is as important as the industrial pollution due to rapid urbanisation. Pollution caused by transportation and vehicles is in the form of exhaust gases, suspended particles, noise, etc. This pollution is minimized by adopting national, regional, and urban planning methods and using proper cars and fuels along with the application of pollution control technology.
Airborne particles or dust in the air are known as particulate matter (PM) and are a type of pollution and one of the most important air pollutants in many areas. PM is made up of tiny solid particles or liquid droplets the size of a fraction of the thickness of a human hair that float in the air. Because these particles are so small, you can't see them individually with the naked eye, but sometimes you can see a dusty cloud that is visible when millions of particles blur the emission of sunlight.
