Air quality in Satun

Does Satun have higher levels of air pollution?

Satun, Thailand, has a varying degree of air pollution throughout the year. Whilst it maintains a generally positive level of air quality, coming in with quite a respectable position in the world ranking of all cities recorded over 2020 (relative to other cities and towns in Thailand, which did not perform so well due to the larger spikes in air pollution seen in certain months of the year, which will be delved into in more detail at the end of the article). In late October of 2021, Satun was seen with a US AQI reading of 41, placing it into the 'good' air quality rating bracket, which is color-coded as green for reference in the various air quality maps, graphs and forecasts present, and requires a US AQI reading of 0 to 50 to be classified as such. Other higher readings taken over a similar time frame went up to heights of 64 and 71, placing Satun into the 'moderate' air quality bracket, which whilst not overtly dangerous, still represents a higher degree of smoke, haze and fine particle pollution in the atmosphere, and as such ill side effects may be sustained for certain individuals. To close the question, Satun maintains a better quality of air as mentioned, although sudden spikes in air pollution may occur, and as such preventative measures such as wearing fine particle filtering masks or avoiding outdoor activities during such bouts of pollution may aid greatly in reducing negative side effects of exposure.

What is causing these higher pollution levels to occur in Satun?

Air pollution has its presence throughout Satun due largely to many of the reasons that afflict other cities, towns and provinces throughout Thailand, as well as neighboring countries, particularly Myanmar in the north. Well-known ones include the burning of vast areas of forest or farmland, done in a practice known as slash and burn farming. Whilst this is most prevalent in the northern regions of the country, it can also affect many other provinces, causing the pollution levels to spike drastically towards the end of the year and stay elevated into the earlier months of the following year, with some cited figures from years past demonstrating this, which will be discussed towards the end of the article. Other causes of air pollution in Satun include exhaust fumes emitted from the many vehicles in use, with a large amount of them being of the aged or defunct variety. Whilst there have been many steps taken to remove those excess 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 causing a reaction take place which forms ozone, or smog as it is more commonly known as). Other sources in Satun 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. The combustion of raw and organic materials remains as one of the more prevalent causes of pollution in Satun, compounded further by anthropogenic and industrial activities.

What are some of the adverse health effects that can occur when exposed to air pollution in Satun?

Extended periods of exposure to higher amounts of polluted air in Satun can cause a large number of highly negative health effects and other serious conditions, particularly pertinent to those individuals who fall under the sensitive group's bracket. Of note though, is that even healthy adults may fall ill or sustain damage when air pollution exposure is excessive or said exposure takes place over a long period (particularly prominent for those who live closer to highly polluted areas, which include industrial districts or near busy roads and highways, where the air quality will be poorer for a much larger portion of the year). Many conditions that can arise as a result would be short-term ones such as dry throat and coughs, as well as chest pains and subsequent infections of the respiratory tract and lungs. These typically resolve themselves fairly quickly when the presence of polluted air is halted. They may, however, potentially evolve or worsen into more long-term or chronic issues, with continuous infections of the chest and lungs, as well as incessant coughing often leading to the scarring and damage of the tissue of the lungs, which can result in permanently decreased lung capacity. additionally, the scarring or damage and inflammation to the tissue of the lungs that can occur from breathing these damaging particles can make individuals much more vulnerable to a whole host of respiratory distress, with chronic obstructive pulmonary disease (COPD) presenting itself. COPD is an umbrella term that encompasses a plethora of lung and respiratory tract ailments, usually resulting in shortness of breath and other unwanted or adverse symptoms. Breathing in polluted air when an individual already suffers from pre-existing conditions can cause them to worsen, and thus progress into potentially more life-threatening forms of said illness. Some of the conditions that can be classified under the COPD bracket are aggravated forms of asthma, as well as emphysema, pneumonia, and bronchitis. 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 an individual’s life expectancy in Satun.

When is the air most polluted in Satun?

Utilizing the data gathered from 2020 as a more complete picture (with such data averages being subject to future updates), it can be seen that Satun had its highest levels of air pollution in January through to March, with all three of these months coming in within the 'moderate' air quality rating bracket. Out of these three, March just came in as the highest with its reading of 12.8 μg/m³. Although these were not perfect readings by any means, they still indicate that despite its more polluted periods, Satun remains significantly less polluted than many other cities in Thailand.

When is the air cleanest in Satun?

In contrast, Satun had its cleanest air quality period in September through to November, all of which fell within the World Health Organization's (WHO's) target goal for the best quality of air at 10 μg/m³ or less. Out of these months, October demonstrated the cleanest level of PM2.5 with a reading of 6.5 μg/m³.
