Sai Mai is one of fifty different districts found in Bangkok and the greater Bangkok area, with air quality to match that of the city in which it is merged. Whilst Thailand has shown over the last few years that many cities, towns and provinces have considerably worse air quality than that of the capital city, it still stands to reason that Bangkok and its many different districts have considerable levels of air pollution, with its large population size, industrial activity and many other factors contributing to these heightened levels seen through certain months of the year. Whilst in this current stage there is a lack of definitive air quality data for Sai Mai from 2021 onwards, this will change soon as new air quality data is added and thus updated information will be added to the article. Observing the current air quality situation in Sai Mai, in early November of 2021, it can be seen that a US AQI reading of 99 was recorded, placing Sai Mai into the 'moderate' air pollution rating bracket. This requires a US AQI reading of anywhere between 51 to 100 to be classified as such, placing it in the absolute highest end of this particular rating, very close to being moved up to the 'unhealthy for sensitive groups' rating bracket (100 to 150). The US AQI reading is a figure aggregated from the various pollutants typically found in the air throughout the world, being the most common forms of pollution caused by combustion, industrial processes (themselves most often going through some form of combustion) as well as human activity. The chemical compounds that go into forming this US AQI aggregate will be discussed in further detail at the end of the article if one wants to find out more about which pollutants are found in the air in Sai Mai and Bangkok. In closing, this is a fairly prominent air pollution reading and thus preventative measures should be taken to safeguard one’s health. Forecasts show further rises in air pollution and thus whilst Sai Mai may have better air quality during certain months of the year, the end of the year may have higher levels of pollution present.
Pollution buildup in Sai Mai is caused by a number of different sources, all being very similar in nature to those that afflict the other districts in Thailand, as well as any major cities in South East Asia. Vehicle fumes are of great concern, especially for these satellite cities and districts of Bangkok, with many people living outside the center of the city as is common worldwide, for lower property prices and potentially better quality of life and so forth, but inevitably the employment is to be found within the inner city and thus the daily commutes are made, causing rush hour traffic (a common theme in Bangkok that many visitors and inhabitants are aware of) to release vast amounts of hazardous particle pollution, clouds of smoke, haze and smog, all with varying degrees of different pollutants in them. Older and lower quality vehicles still remain prevalent, even though there are many incentives in place to gradually phase them out altogether. This will aid greatly in pollution reduction in the major cities of Thailand but may prove much greater of a task in provincial areas throughout the countryside where ancient motorbikes, cars and trucks remain in use, leaking much larger amounts of noxious oil vapors due to their poor engine quality, as well as their exhaust fumes spitting out great clouds of dark smoke. Furthermore, vehicles contribute to other forms of particle pollution, with the consistent wear and tear placed on tire treads giving rise to large amounts of microscopic rubber particles entering into the atmosphere. From here they can cause a great number of health issues when inhaled, triggering off pre-existing health conditions as well as potentially entering into the bloodstream if their size is small enough (more on these details later when discussing PM2.5 and its nature), as well as accumulating in the environment and wreaking havoc on ecosystems. Other causes of pollution present in Sai Mai include smoke and haze from industrial activity, as was mentioned, with various industrial sites, factories, power plants and even private businesses that rely on the combustion of fuels, or even fossil fuels such as diesel, natural gas and coal to provide their energy needs. Other ones of note include dust given off from construction sites and road repairs, as well haze floating over from other provinces where slash and burn farming practices are still more heavily relied upon, despite being made illegal. This can cause seasonal spikes in pollution to occur, with the latter months of the year, namely September or October onwards, through to the early months of the following year, typically abating around April or May, with many variations present throughout the country.
Vulnerable groups that should take extra care during bouts of higher air pollution include young children and babies, as well as pregnant mothers. The elderly are also vulnerable, as well as those with compromised immune systems, pre-existing health conditions and those with a hypersensitive disposition towards particles or certain chemical pollutants.
Health effects that can be incurred from incessant pollution exposure include chronic obstructive pulmonary disease (COPD), which includes within it conditions such as pneumonia, asthma, bronchitis and emphysema. Besides having a myriad of superficial damaging effects such as causing skin issues, more serious issues also include a higher risk of heart attacks, strokes, arrhythmias and premature death, directly linked one way or another with air pollution exposure.
Some of the main pollutants that one may find in Sai Mai include those in the US AQI aggregate, namely nitrogen dioxide, ozone, sulfur dioxide, carbon monoxide as well as the two main forms of particle pollution, PM10 and PM2.5, with the latter being the far more dangerous of the two. PM2.5 is a pollutant (made up of a variety of different and highly damaging or carcinogenic materials) that is 2.5 micrometers or less in diameter, going down to sizes many times smaller depending on the material. This allows it to penetrate the lung tissue and enter the bloodstream. Black carbon is one example of an extremely dangerous and prevalent form of particle pollution.
