Qualité de l’air à Sam Ngam

How polluted is the air in Sam Ngam?

The air in Sam Ngam is quite highly polluted, as evidenced by air pollution records taken in the early months of 2022, with US AQI levels staying high from January through to mid-March, and likely to continue for a while longer (before typically abating in the mid-period of the year). US AQI readings of 155 were detected, placing Sam Ngam into the 'unhealthy' air quality rating bracket, which indicates a fairly dangerous level of smoke, haze and ultrafine particles being present in the air. Whilst this will not stay at such a sustained height for the whole year, it is wise to take precautions (as well as staying up to date on air pollution levels) during times of higher pollution readings.

Why is the air so polluted in Sam Ngam?

Some of the main causes of air pollution that are prominent throughout Sam Ngam include emissions from factories, power plants and other industrial sites, as was briefly mentioned above. Exhaust fumes from vehicles are also a constant issue, due to increasing vehicle ownership across the country, along with older and more defunct models of cars, motorbikes and trucks still being used, particularly in rural areas. These lower quality engines can spit out considerably more noxious oil vapors and particles such as black carbon due to the poor combustion process taking place within the engines. Other sources of note include dust and fumes from construction sites, along with poorly paved roads, road repairs and other similar sites adding to the PM10 and PM2.5 levels. Additionally, the issue of slash and burn farming has the potential to affect air quality in Sam Ngam, with all of these aforementioned factors coming together to cause the spikes in the pollution levels witnessed in Sam Ngam.

What health issues does breathing pollution in Sam Ngam cause?

Many health issues can indeed be caused with a direct link to air pollution levels, and how much an individual takes in over any given period (with both acute and chronic cases having their ailments that come from said exposure). Illnesses that occur are most likely to be of the pulmonary variety, affecting the lungs, respiratory tract as well as causing irritation to the mucous membranes such as the eyes, ears, nose and mouth. Dry coughs can occur, along with infections of the respiratory tract which can easily worsen if pollution exposure is sustained over long periods in Sam Ngam.

What can be done to lessen the impact of air pollution in Sam Ngam?

To reduce the air pollution levels in Sam Ngam by any significant amount (and at any rate, this would not be an overnight fix but one that would likely take many years to slowly implement, and then see the effects), both big organizations such as ones in charge of factories and power plants would need to change their approach. This ties in closely with the law, as if certain rules are not both put into legislation, as well as enforced (this being the most important aspect of it), then many organizations are inevitably going to continue in their old ways. The reduction of fossil fuel usage would be one of the main steps towards reducing pollution levels in both Sam Ngam, as well as the rest of Thailand and indeed many neighboring countries (with a majority of Southeast Asian countries suffering from the same pollution causes).

As it is hard to implement this with any rapidity, certain factories and plants can implement ways to reduce the amount of pollution that is released into the atmosphere as a result of burning fossil fuels. Low-cost carbon filters can indeed remove large amounts of carbon dioxide from smoke, and other similar filters can also aid in removing the dangerous particles and chemical compounds that go into forming the smoke clouds that inevitably make their way into the atmosphere. The removal of extremely decrepit cars from the roads can also have a significant effect, and lastly, continued crackdowns on slash and burn farming practices would also help reduce the large air pollution spikes seen in Sam Ngam for certain months of the year.

Which people are most at risk when it comes to air pollution exposure in Sam Ngam?

Whilst there are certainly more vulnerable members of the population within Sam Ngam, those that are more gravely affected by pollution exposure, it is of significant importance to note that any level of air pollution at all, carries with it the possibility to cause unfavorable health effects amongst those who are exposed, including both young and healthy citizens or those with no prior health conditions. Clouds of smoke and fine particles may trigger sudden immune responses, cause health conditions related to the skin, lungs and heart (in more severe cases) to arise. Directing back to the question, those who are more at risk include groups such as younger children and babies, both of whom are highly vulnerable to the damaging side effects of chemical and particle exposure. Alterations to the nervous system can take place, due to many chemical compounds having this property when they accumulate in large enough quantities within the human body.

This may result in delayed growth, as well as developmental problems and impaired mental capabilities, with youths who suffer from excessive pollution exposure for many years sometimes having these ailments, as well as sustaining damage to their lungs and other organ systems. This can once again have a domino effect of stunting development as well as leading to other lifelong health issues. Other groups that fall into the sensitive bracket are pregnant women, who much like the young children and baby demographic, can subject their unborn child to the negative side effects of pollution exposure due to certain hazardous chemicals being able to make their way to the child in the womb, causing instances of babies being born prematurely, with low birth weight, as well as increasing the rates of infant mortality.

Elderly citizens in Sam Ngam are also at risk, due to them being more prone to suffering from respiratory or cardiac ailments. Common chest or upper respiratory tract infections may develop into more life-threatening or terminal illnesses amongst the elderly, with other comorbidities such as sedentary lifestyle, pre-existing health conditions, obesity, or habits such as smoking lending themselves to making these conditions extensively worse. Lastly, many people can exhibit a hypersensitive disposition towards certain ultrafine particles and other chemicals found in the pollution in Sam Ngam. As such, all of these groups would do well to stay up to date on the pollution levels, both for the current day as well as the predictions for the coming week. Preventative measures such as wearing fine particle filtering masks and avoiding outdoor activities can aid considerably in reducing more serious side effects.
