How to best protect from air pollution?

Reduce your air pollution exposure in Yanliang


Does Yanliang have badly polluted air?

Yanliang has some fairly bad levels of air quality on record, coming in repeatedly with many months of the year having high pollution readings. Looking at the readings taken in the latter days of April 2021, Yanliang was seen with a US AQI reading of 95, a reading that placed it into the ‘moderate’ air pollution bracket. This indicates that whilst the air quality is not overtly bad, it would still have a fair amount of pollution and air contaminants in the atmosphere to warrant some concern, with sensitive individuals being at risk for adverse effects, particularly during time periods in which this number goes higher.

The current level of air pollution can be followed by utilizing air quality maps, such as the one present at the top of this page, as well as on the AirVisual app. US AQI as a unit of measurement is a composite number calculated from the main pollutants found in the air, some of which include PM10, PM2.5 (which is an equally important measure of air pollution in its own right, and will be discussed in further detail), as well as chemical compound such as ozone (O3), or smog as it is better known when it accumulates in large enough quantities.

Observing the levels of US AQI taken prior to the above reading, it can be seen that over the course of both March and April, far higher readings were present, with numbers such as 152, 156 and 197 all being present. These readings would all sit within the ‘unhealthy’ air quality ratings bracket. On days such as these, vulnerable groups would be even more susceptible to adverse health effects, and even healthy individuals would be at risk to developing some symptoms, typically related to the respiratory tract, as well as the skin, mucous membranes and heart all being vulnerable to damage. This risk is heightened when overexposure to pollution takes place over a longer period of time.

Why does Yanliang have higher pollution levels?

Yanliang has higher levels of pollution present due to the many reasons that other cities in China see elevated PM2.5 readings. Rapidly growing population size, coupled with massive increase in industry along with demand for housing and other related aspects all contribute heavily to pollution levels, particularly when less stringent measures are in place. When left unchecked, many industrial areas, factories or even personal businesses can put out larger amounts of pollution that far exceed the safe limit, and although the rules are rapidly changing across the country, it still remains to be seen that many cities, Yanliang included, still suffer as a result of excessive pollution from factories, power plants and the variety of other industrial sites.

In 2020, Yanliang came in with a PM2.5 reading of 51 μg/m³, placing it within the ‘unhealthy for sensitive groups’ bracket of air quality, which requires a PM2.5 reading of anywhere between 35.5 to 55.4 μg/m³ to be classified as such. As can be seen, this reading is on the higher end of this ratings bracket, and actually worsened from the year prior, with 2019 having a PM2.5 reading of 45.5 μg/m³, still within the same pollution rating but still lower and thus representing a somewhat better quality of air.

This PM2.5 reading of 51 μg/m³ placed Yanliang in 36th place out of all cities ranked in China, showing what a marked effect that the various polluting sources have on the air quality of the city. It also ranked in at 94th place out of all cities across the globe in 2020, putting it within the very undesirable category of top 100 most polluted cities worldwide.

Other causes of air pollution that contribute to these poor placings include ones such as dust storms, blown in from outside of the city, as well as emanating from construction sites, demolition areas, poorly paved roads, as well as any industry or activity that sees largescale disturbance of earth or the soil. This can release many tons of both fine (PM2.5) and coarse (PM10) particles in the air, some of which have extremely adverse effects on human health when inhaled (with ones such as silica dust having carcinogenic properties, whilst others such as regular dirt or finely ground gravel dust can cause scarring and inflammation of the lung tissue and respiratory tract).

When is Yanliang subject to higher bouts of air pollution?

Observing the data recorded over the course of 2020 as an accurate measure of long term pollution buildups throughout the city, it can be seen that the months at the very beginning and end of the year were the most polluted. This indicates a pattern whereby the pollution levels start to rise at years end (with September through to November showing a rapid increase in PM2.5 readings), and continue on in their elevated state into the early months of the following year, before dropping down to more appreciable levels.

January and February, as well as November and December all came in with the highest readings of PM2.5, with respective numbers of 121.3 μg/m³, 67.5 μg/m³, 70.4 μg/m³ and 86.9 μg/m³ all being taken. This indicates that January was the most polluted month of the year by a significant amount, with all the aforementioned readings falling into the ‘unhealthy’ ratings bracket. To attain this rating, a reading must come in between 55.5 to 150.4 μg/m³ for classification.

When do pollution levels drop in Yanliang?

After the heightened periods of air pollution came to an end and start to drop in March, Yanliang enters into a time period in which the air quality sits in the ‘moderate’ ratings bracket for a long stretch of time, taking up a large portion of the year. May through to September all have the best readings of PM2.5 present over the course of 2020, with August being the cleanest month with a reading of 23 μg/m³.

What are the main types of pollutants in the air in Yanliang?

The main pollutants found in the air in Yanliang would be ones such as black carbon, which besides falling into the particulate matter collective, is also the main component in soot and a potent carcinogen when inhaled. Volatile organic compounds (VOCs) would be prevalent around industrial areas, with chemicals such as benzene, formaldehyde, styrene and toluene all falling under this category.

Cars and industrial areas would release large amounts of nitrogen dioxide (NO2) and sulfur dioxide (SO2), both of which are also used to calculate the overall level of US AQI as mentioned earlier. Other pollutants include heavy metals such as mercury and lead, dioxins, furans, polycyclic aromatic hydrocarbons and even large amounts of finely ground plastic and rubber particles, given off from tire treads, industrial processes and the incorrect disposal of waste.
