As of late February in 2022, Dasna was continuing to present with high levels of air pollution, carrying on from January and early February, both of which saw significant levels of pollution readings present. This indicates that Dasna has high amounts of haze, smoke, hazardous particulate matter as well as a multitude of dangerous chemical compounds floating around in its air. These can cause many health issues, which will be discussed in further detail in some of the following questions. A US AQI reading of 176 was recorded in late February, placing Dasna within the 'unhealthy' air quality rating bracket, color-coded as red and indicating that the air quality would be permeated with enough pollution to cause breathing difficulty and many other respiratory (and in more serious cases, cardiac) issues amongst its citizens, particularly for those that are more vulnerable. At the time in which the above-mentioned reading was taken, the PM2.5 concentration was found to be nearly 21 times over the World Health Organization's (WHO's) safe exposure guidelines, a considerable amount. Due to the highly dangerous nature of pollution that falls under the PM2.5 collective (that is, any material that is 2.5 micrometers or less in diameter, sometimes going down to sizes many microns smaller), large concentrations such as the ones present in Dasna should not be taken lightly, and as many preventative measures (such as wearing ultrafine particle filtering masks and avoiding outdoor movement) should be taken as possible, to avoid the negative health effects brought about by highly polluted air. Other noteworthy US AQI readings taken around the same time went as high as 279, placing Dasna into the very unhealthy rating bracket for that particular day. As such, Dasna can indeed be considered as a city with quite bad air pollution.
The main causes of air pollution in Dasna include exhaust fumes emitted from the many vehicles in use, with a large amount of them being aged, or of much poorer quality. Whilst there have been many regulations put into place to remove those more prominent pollution-causing vehicles from the roads, particularly in major cities, their use is still prevalent throughout many rural areas or outside the larger or more densely populated regions. Due to the extremely poor combustion process that takes place (often coupled with low-quality fuels or fossil fuels), considerably higher amounts of noxious oil vapors are released into the atmosphere, along with the usual chemical compounds such as nitrogen dioxide, sulfur dioxide, carbon monoxide, ozone (which forms afterward as the various pollutants are exposed to solar radiation, thus forcing a reaction take place which forms ozone, or smog as it is more commonly known as). Other causes include factories and power plants, which also rely heavily on burning fossil fuels to meet their power needs. Road repairs, construction sites, and other similar areas also release high amounts of ultrafine or coarse particles into the air, raising the PM2.5 and PM10 levels, which can cause prominent spikes in the particle pollution readings. Industrial activities and fumes from vehicles remain as one of the more prevalent causes of pollution in Dasna, made worse by constant anthropogenic and industrial activities that leave pollution in their wake, as well as smoke from neighboring regions drifting in under the correct meteorological circumstances.
Exposure to high levels of air pollution in Dasna can bring about all manner of dangerous conditions, particularly to certain individuals who fall into the more sensitive or vulnerable group bracket. However, even healthier and younger adults can potentially succumb to the adverse effects of air pollution, if said exposure is excessive, or taken in over a long time (particularly for those who live near highly polluted areas such as industrial zones and districts, or nearer to busy roads and highways, where the air quality will be of significantly poorer quality for much of the year). Many conditions that may arise as a result of breathing excessive amounts of pollution in Dasna would be the standard short-term illnesses such as dry throat and coughs, as well as chest pains and mild infections of the respiratory tract. These can potentially resolve themselves quickly when exposure to air pollution is lessened or ceased altogether, and as such, they can be considered as more short-term or acute health issues. There is the possibility, however, that they may also develop into more long-term or chronic issues, with continuous chest infections and coughing leading to the eventual scarring of lung tissue, which usually results in permanently decreased lung capacity. As well as this, the scarring or damage and inflammation to the tissue of the lungs can make one more vulnerable to a whole host of respiratory distress, with chronic obstructive pulmonary disease (COPD) presenting itself. This is an umbrella term that refers to a multitude of different lung and respiratory tract conditions, typically resulting in shortness of breath as well as making an individual at greater risk of severe damage from pollution exposure. Some further conditions that fall under the COPD bracket are one such as pneumonia, bronchitis, emphysema as well as asthma. Other forms of damage that can happen within the body include increased risk of cancer, heart attacks, strokes and arrhythmias, as well as ischemic heart disease and many other cardiac or pulmonary conditions that can bring about decreased quality of life as well as lower life expectancy within Dasna.
Those that are more vulnerable to falling ill or having pre-existing conditions worsened by pollution exposure in Dasna include the elderly, who are particularly vulnerable to both cardiac and pulmonary ailments. Other at-risk groups include those with poor or compromised immune systems, as well as those with a hypersensitive disposition towards certain chemical compounds or fine particles (which can be brought on by health conditions). Babies, children and pregnant women are also at further risk of pollution-related illnesses, and as such these groups should all take utmost precaution during bouts of extreme spikes in the US AQI and PM2.5 levels.
Pollutants that would be found in the air in varying concentrations throughout Dasna would be those that are used to calculate the US AQI reading, namely sulfur dioxide, carbon monoxide, nitrogen dioxide, ozone and the two main forms of particle pollution, PM10, and PM2.5, with the latter being the far more dangerous of the two due to its extremely small size. Other pollutants include a whole host of volatile organic compounds (VOCs), as well as black carbon, both of which are released from the combustion of fossil fuels and organic matter within Dasna and other nearby cities.
