Qualité de l’air à Mueang

Is there air pollution present in Mueang?

Air pollution is fairly present in Mueang, with some months showing higher and more dangerous readings. In late September of 2021, US AQI readings of 61 were recorded, placing Mueang into the 'moderate' air quality rating bracket, indicating pollution levels that could start to cause respiratory distress amongst the general public and more specifically, vulnerable individuals. Whilst this reading was seen on one day, many other days before this showed more optimal readings of US AQI levels, although of note is that September is one of the cleaner months that Mueang experiences, based on readings from past years. As such, Mueang can be considered to be having decent air quality during certain times of the year, but caution should be practiced and air pollution levels monitored through other months of the year in order to gauge when the air quality levels are safer to breathe.

Why is air pollution prevalent in Mueang and what are the main causes?

Air pollution has a prevalence in Mueang due to many of the reasons that afflict other cities, towns and regions throughout Thailand as well as neighboring countries. These include ones such as the burning of vast swathes of forest or farmland, conducted 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 early months of the following year, with some cited figures from years past demonstrating this, which will be discussed in the last two questions of the article. Other causes of air pollution in Mueang include exhaust fumes emitted from the numerous vehicles in use, with a large amount of them being of the aged or defunct variety. Whilst many steps have been 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 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. The combustion of raw and organic materials remains as one of the more prevalent causes of pollution in Mueang, compounded further by anthropogenic and industrial activities.

What are the health risks of overexposure to polluted air in Mueang?

Health risks that can occur when individuals are exposed to high levels of air pollution are numerous and typically affect the respiratory and cardiac systems the most, as well as affecting other organ systems such as the nervous system, the skin and others such as hepatic and renal functions (due to them being the bodies filtration units, or liver and kidneys, thus bearing the brunt of removing contaminants that have been taken into the body through breathing polluted air or ingesting contaminated food that has been tainted to do also being exposed to chemical compounds and fine particles, moving their way up the food chain). Certain individuals are also more at risk when it comes to being exposed to pollution, and these include groups such as the elderly, young children and babies, pregnant women, as well as those with pre-existing health conditions, compromised immune systems (usually as a result of the aforementioned health conditions causing the immune response to be lacking in the body) as well as those who have a hypersensitive disposition towards certain irritating chemicals or particles. As well as this, those who lead unhealthy lifestyles such as being sedentary, overweight or partaking in smoking may be at higher risk of incurring further adverse effects when exposed to excess levels of pollution.

Some conditions that would appear would be those that fall under the chronic obstructive pulmonary disease (COPD) bracket, with COPD being an umbrella term that addresses several different respiratory diseases that prevent the lungs from taking in full amounts of air. Excess inhalation of damaging particles can cause scarring of the lung tissues, leading to decreased oxygen intake, as well as making those affected more susceptible to further respiratory conditions. More common ailments that fall under the COPD bracket include asthma and aggravated forms of it, along with pneumonia, bronchitis and emphysema, all of which can reduce one’s life span as well as the quality of life. Other issues include increased rates of cancer, due to the carcinogenic properties of many of the pollutants that are found in the air (with ones such as benzene being highly carcinogenic, along with silica dust and black carbon also being found to have the same properties. Benzene falls under the volatile organic compounds (VOCs) bracket, which are released in large amounts from the combustion of both fossil fuels and organic matter, as well as emanating from a variety of household products, varnishes, glues and paints). More serious conditions include a higher risk of heart attacks and their repeated occurrence, along with strokes, damage to the nervous system (particularly prevalent amongst those that are young and still developing), as well as arrhythmias, angina and death in more extreme cases, with many instances of premature death being directly linked to excess pollution exposure, highlighting how important it is to keep one’s exposure to an absolute minimum wherever possible.

When is the air more highly polluted in Mueang?

Taken from the PM2.5 readings of 2020, the month that had the highest level of pollution was March, with a reading of 42.6 μg/m³, placing it into the 'unhealthy for sensitive groups' bracket and the only month to achieve such a rating. Whilst data was missing for January and February, it can most likely be assumed that their pollution levels were also elevated, based of patterns typically seen in many Thai cities in the earlier months of the year.

When is the air quality cleaner and improved in Mueang?

The months of June through to September had the cleanest levels of air quality present in Mueang, all of them coming in within the 'good' air quality rating bracket, which requires a PM2.5 reading of 10 to 12 μg/m³ for classification. Out of all of these, June had the cleanest level of air quality with its reading of 10.1 μg/m³.
