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

There is a lot of extremely interesting information about air quality and it is very easy to access from the main city page. The map will be seen at the top of the main page and clicking on it will command a new page to open which will be filled with all relevant information about air quality.

The background colour of the map reflects the current air quality with available colours ranging from pale green to dark maroon where the darker colours indicate worsening quality. These colours are standardised across the entire IQAir website. The viewer will also notice several coloured discs that are scattered across the screen. These show the locations of the ground-level air monitoring stations in and around the city, although they are not all specific to Las Vegas. If the discs are overlapping each other, slightly expanding the map will cause them to separate and thus become easier to differentiate from each other. Each area can be explored further by selecting the appropriate disc.

At the centre of each disc can be seen a number which is the United States Air Quality Index reading or US AQI for short. This reading is calculated by taking measurements of the top six most commonly found pollutants in the city air. These are nearly always both sizes of Particulate Matter (PM2.5 and PM10), nitrogen dioxide, sulphur dioxide, carbon monoxide and ozone. The entire system is endorsed by the World Health Organisation (WHO) and is used as a standard when comparing the levels of air quality in different cities around the world.

Looking back to the main city page, it can be seen in the coloured banner at the top of the screen that at the start of 2023, Las Vegas was enjoying a period of “Good” air quality with a US AQI reading of just 15. The main pollutant was found to be PM2.5 with a recorded level of 3.6 µg/m³ which is well within the recommended target level of 5 µg/m³ as suggested by the WHO.

Immediately below the air pollution map for Las Vegas can be seen the number of contributors there are that collate all the data about air quality. It also shows the number of stations there are that provide the essential data. This figure currently stands at 22. Two of the contributors are government agencies whilst the remaining fourteen prefer to remain anonymous. The Clark County Department of Air Quality operates eight of the stations.

Is there any more valuable information about air quality on the air pollution map for Las Vegas?

There is more very interesting information to be found on the air pollution map for Las Vegas, but to be able to see all of it, the page needs to be looked at at maximum size. This is easy to achieve because the icon to enable this can be seen on the top right-hand side of the opening page.

When full-screen viewing has been enabled, there will be a list of four options to be seen on the left-hand side of the screen. These can all be turned on or off individually to see the effect each one has on the map.

The first option shows the locations of the ground-level air monitoring stations in and around the city. If an area is of specific interest, the closest disc can be selected and a new page will open which is filled with all relevant information about that precise location.

The next option reveals the location of any wildfires that might be burning out of control in the vicinity. In mid-January 2023, they were no such icons on the map which meant there were no reported fires in the area. If fires are present, then option four will be a very useful tool because it shows the wind speed and direction and will give a good indication of where the smoke from the blaze may blow.

The third option governs the overall background colour of the map to visually show the current quality of the air. If the colour is too intense and confusing, it can be deactivated so the map will revert to a more acceptable colour palette.

The remaining information is found on the right-hand side of the screen where a table can be seen that ranks the top seven cities with the worst air pollution. If this topic is of interest, then the full-ranking option should be explored which shows all participating world cities in descending order of pollution levels.

Can the source of the air pollution be seen on the air quality map for Las Vegas?

The source of the polluted air is not directly visible on the air quality map for Las Vegas, however, it is known that transportation, the construction industry and a rapidly growing population all contribute to poor air quality. The relative lack of rain, high temperatures and long hours of sunlight almost encourage the growth of ozone due to a large number of nitrogen oxides and volatile organic compounds. The recent drought conditions have caused more dust to blow into the city which is a part of the elevated levels of PM2.5. As recently as 2020, Las Vegas experienced 81 days with elevated ozone and 32 days with elevated PM2.5 pollution. These elevated levels of PM2.5 have got worse recently because of the rise in the number of wildfires burning in the area.

How dangerous is PM2.5?

Particulate matter (PM) is particles suspended in the air. These particles are solid and liquid and many of them are dangerous to human health in the both short and long term. Particulate matter is a mixture of particles of organic and inorganic origin and varies greatly in size and composition.

Particulate matter has harmful effects on health, even in the absence of other air pollutants. Fine particles are more dangerous than coarse particles. In addition to the size of the particles, other specific physical, chemical and biological properties can influence adverse health effects. PM2.5 can easily travel through the airways and reach the lungs.

Exposure to fine particles may cause many short-term detrimental health effects, including irritation of the eyes, nose, throat and lungs. You may experience coughing, sneezing, runny nose and breathing difficulties too. Exposure to fine particles can also affect lung function and worsen pre-existing medical conditions, such as asthma and heart disease. People who already suffer from respiratory and heart problems are particularly sensitive to PM2.5, as well as children and the elderly.
