Observing air pollution levels on record in the early days of March 2022, Samphanthawong is showing higher figures of both US AQI and PM2.5, with readings spiking up by considerable amounts, indicating that the air would be permeated by smoke, haze and fine particulate matter in certain areas throughout Samphanthawong. To cite an example (with these figures likely to persist until late April and potentially beyond, depending on meteorological conditions and a few other factors), a US AQI reading of 124 was taken in March, placing Samphanthawong into the 'unhealthy for sensitive groups' air quality rating bracket. Other readings went even higher, up to 152 in late February of 2022, pushing Samphanthawong up a notch into the 'unhealthy' air quality bracket. These are indicative of poor air quality, and whilst they will not persist for the whole of the year (although this may be possible if certain natural or man-made disasters happen to appear), the air quality in the earlier months can potentially cause many health issues amongst the citizens of Samphanthawong.
Causes of air pollution within Samphanthawong stem mainly from exhaust fumes given out by cars, particles released from construction (and even demolition) sites, along the burning of fossil fuels in the many industrial sites and factories surrounding Samphanthawong in the greater Bangkok region. As touched on earlier, there is the potential for pollution to reach Samphanthawong from open burn sites in the more northern regions of the country. All of these factors can come together to form the higher levels of US AQI and PM2.5 seen on record both in 2022 and years past.
Some of the main air pollutants found within Samphanthawong include those that go into forming the US AQI figure, which itself is an aggregation of the following chemical compounds: ozone (or smog as it is more commonly referred to when it accumulates in large enough quantities), nitrogen dioxide, sulfur dioxide, carbon monoxide and the two main forms of particle pollution, PM2.5 and PM10.
Extended periods of exposure to high levels of air pollution in Samphanthawong can cause many dangerous health conditions to occur, with this being particularly pertinent to individuals who fall into the sensitive group demographic, which will be covered in slightly more detail in the following question. Despite certain groups being more at risk, healthy adults without any pre-existing health conditions may also find themselves at risk to the negative side-effects of polluted air in Samphanthawong, particularly if exposure takes place over a longer period. This is of more importance for those that find themselves living near much more highly polluted areas such as industrial districts or near busy roads, where the air quality is often of much poorer quality, with hazardous particles, smoke, smog and haze being far more prevalent in the atmosphere for much of the year.
A larger number of ailments that may show themselves amongst the inhabitants, would be the shorter-term ones such as dry throat and coughs, as well as the accompanying chest pains and infections of the upper respiratory tract. These can usually typically resolve themselves in a relatively short amount of time when the exposure to air pollution is stopped or reduced.
As such, they can be classified as more acute health issues amongst potential health problems present in Samphanthawong. With non-stop air pollution exposure transpiring, respiratory issues may also grow into more long-term, chronic health problems. The constant chest infections sustained as well as the accompanying coughing can lead to the scarring of lung tissue, which can result in a significantly (and often permanent) 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 in Samphanthawong.
Observing the air pollution patterns that take place throughout the whole of Thailand, year after year, it is more than likely (although not without potential deviations) that Samphanthawong will be subject to the highest levels of air pollution at the same time that many other cities, towns and provinces in Thailand also see them, with larger amounts of smoke, haze and hazardous ultrafine particles permeating the air to a more dangerous extent during such months. Due to being part of the greater Bangkok region, however, Samphanthawong will also see much larger contributions to its pollution levels from anthropogenic and industrial activity, when compared to areas in the northern or central regions of Thailand. These northern regions tend to be affected more gravely by pollution from open burn sites, although Bangkok can still be subject to rapid pollution buildups and spikes due to smoke being blown over it during certain times of the year.
Due to the countrywide issue of slash and burn farming practices, many of the air pollution readings throughout Thailand tend to follow the seasonal burning, with some cities in closer proximity to these practices following them almost directly, with higher pollution levels appearing as soon as the burning starts to take place, and abating around the time that it comes to an end, although residual clouds of smoke and haze can cause prolonged elevations in the US AQI and PM2.5 (and PM10) count. Furthermore, adverse weather conditions such as a lack of rain (which aids in removing some of the larger particles from the air by tamping them down, but has shown to not have a significant effect on ultrafine particles and any polluting gases that may be in the air) as well as lack of wind also playing a role in how long the pollution levels stay elevated.
This remains true for pollution caused both by open burning as well as the myriad of other polluting sources. Wind remains as one of the most effective removers of air pollutants, with strong winds rapidly removing large amounts of hazardous accumulations (albeit not removing it entirely as they can be blown over to nearby towns and cities, although the overall dispersal of gases and particles can serve to lessen their ill effects). With all these facts noted, as well as the pertinent point of deviations from the norm always being possible (another case as to why pollution levels should be carefully monitored, with forecasts being available both on this page as well as the AirVisual app), it remains that Samphanthawong and indeed many areas throughout Thailand tend to see heightened levels of pollution crop up in the latter portion of the year, typically starting around September through to October, and going through to the next months of the following year, with some of these early months seeing the highest air pollution levels (once again this is based on a large number of readings taken from many cities, as an average). Air pollution levels start to recede around March or April and can give way to the middle months of the year seeing the best (or in some cases mildly improved, still lacking perfectly clean air) readings of US AQI and PM2.5, making the beginning and end months of the year the time in which Samphanthawong is most likely to be polluted.
