Wuhan MAP AIR QUALITY ANALYSIS AND STATISTICS

What information about air quality can be found on the air pollution map for Wuhan?

The air pollution map for Wuhan is very easy to find from the main city page. It can be found towards the top left-hand side of the opening page.

When first opened, the viewer will see an overall colour as the map background and several coloured circles, each displaying a number. The significance of the colouration is explained in the legend found at the foot of the page. The colours range from pale green to dark maroon, representing “Good” to “Hazardous” air quality. The numbers which are displayed within the circles are the US AQI numbers. These are calculated by measuring the levels of up to six of the most common air pollutants and it is then used as a standard when comparing air pollution in cities anywhere in the world. It is endorsed by the World Health Organisation (WHO).

Looking back to the main city page, it can be seen that during August 2022 Wuhan was experiencing a period of “Moderate” air quality with a US AQI reading of 54. All six of the major pollutants were measured but it was PM2.5 that is often used as the benchmark. Its level was recorded as being 8.5 µg/m³ which is 1.7 times higher than the 5 µg/m³ target figure as suggested by the WHO.

Is there more information available on the air pollution map for Wuhan?

When the air pollution map for Wuhan is first accessed from the main city page, the viewer will be presented by four options which appear on the left-hand side of the screen. These appear when the map is viewed in full-screen mode and can be deactivated individually if desired.

The first option shows the position of all the ground-level air monitoring stations in and around the city. As previously stated, they are represented by the coloured circles. The second choice shows the position of any wildfires that are burning within the vicinity. In August 2022 there was one fire burning in the Qingshan District. When option four is considered at the same time, it shows the direction of the prevailing winds. The ensuing smoke from the fire will most likely be blown away from the city as can be seen by the latest wind direction.

The third option is perhaps the most impressive as it can change the entire background colour of the map which represents the overall air quality. It can be seen that there are several shades on this map which range from greenish/yellow to reddish/brown. This gives a visible indication as to where the heavy air pollution is found. If the colours are confusing, they can be deactivated and the map will revert to a more standard set of colours which some may find easier to understand.

Over on the right-hand side of the screen can be seen a table which ranks world cities according to their air quality. Some countries may appear as a surprise as they are not usually thought of as being polluted.

Directly below the map can be seen the number of stations which provide the air quality data. Currently, this figure stands at 16 and they are all operated and controlled by government services.

Are areas of higher pollution easy to identify on the air quality map for Wuhan?

There are a couple of options when looking for the most polluted area in the city. The first would be to look on the map and identify the circle that carries the highest number or is a darker colour than the rest.

Alternatively, directly beneath the air pollution map for Wuhan is found a table which ranks all the monitoring stations according to their levels of pollution. Currently, the one showing the highest levels is the Chemical zone station showing a US AQI reading of 117 which is classified as being “Unhealthy for sensitive groups”.

Below this table can be found another which ranks the stations according to the number of followers they have. The most popular one at the moment is the Hankou River Beach with almost 18,000 followers.

Is the source of air pollution shown on the air quality map for Wuhan?

The source of the polluted air is not directly shown on the air pollution map for Wuhan, but it is proven to be from coal combustion, motor vehicle emissions, industry, construction and traffic dust. Some polluted air also travels down from the north and can sometimes linger around Wuhan due to adverse climatic conditions at certain times of the year.

Since 2013, through continuous air pollution control, the city's air quality has generally maintained a trend of improvement, but the situation is still very serious, especially since the pollution levels of ozone and nitrogen dioxide have shown a clear trend of increasing in recent years.

The heavy chemical industry in the city emits a large amount of air pollution, and key industries such as thermal power, steel, coking, petrochemical, chemical, and building materials account for nearly 80 per cent of the city's industrial emissions. In 2020, the city focussed on "controlling increments and removing stock" to force industrial transformation and encourage upgrades.

PM2.5 is often quoted on the air pollution map for Wuhan, but what is it?

PM2.5 refers to particulate matter in the atmosphere with a diameter of less than or equal to 2.5 microns, also known as particulate matter that can enter the lungs. Its diameter is less than 1/20 the thickness of a human hair. Although PM2.5 is only a very small component in the composition of the earth's atmosphere, it has important effects on air quality and visibility.

Compared with the coarser atmospheric particles, PM2.5 has a smaller particle size, is rich in a large amount of toxic and harmful substances, and has a long residence time in the atmosphere and a long transportation distance, so it has a greater impact on human health and the quality of the atmospheric environment.

Respirable particulate matter and total suspended particulate matter in daily or weekly urban air quality reports are two of the more familiar air pollutants. Inhalable particulate matter, also known as PM10, refers to particles with a diameter equal to or less than 10 microns that can enter the human respiratory system; total suspended particulate matter is also known as PM100, that is, particles with a diameter less than or equal to 100 microns.
