Qualité de l’air à Song Phi Nong

Is the air in Song Phi Nong very polluted?

Pollution levels in Song Phi Nong have shown mild to more serious elevations in the earlier months of 2022, a pattern that tends to repeat itself every year. Whilst the air quality is not as poor as other cities throughout Thailand, particularly those of the northern regions where great quantities of smoke, haze and particulate matter can accumulate over cities as a result of open burning practices taking place (which are illegal but still manage to occur due to several reasons, the difficulty of policing and preventing them being one). In mid-February of 2022, Song Phi Nong was on record with a US AQI reading of 97, placing it into the higher end of the 'moderate' air pollution rating bracket, which requires a reading of anywhere between 51 to 100 to be classified as such. Although this reading still sits within the 'moderate' bracket, its proximity to the next pollution bracket, that of the 'unhealthy for sensitive groups' one, may give rise to instances of respiratory irritation amongst the general public, particularly for those with a sensitive disposition towards chemical pollutants and ultrafine particles. when the above-mentioned reading of 97 was taken, the PM2.5 concentration was found to be nearly 7 times higher than the World Health Organization's (WHO's) safe exposure guidelines, indicating that there is an excess of particulate matter in the air. Due to the microscopic size of PM2.5 (being any particle that is 2.5 micrometers or less in diameter and consisting of a myriad of materials such as metals, nitrates and sulfates, water, oil or other liquid vapors, silica dust, bacteria and many others that have the potential to cause great harm, not only to people but also the environment), a heightened can indicate that the air quality in Song Phi Nong could certainly stand to improve.

What health problems can be caused by higher levels of air pollution in Song Phi Nong?

Health issues that may arise from air pollution exposure in Song Phi Nong include those that primarily affect the cardiac and pulmonary systems, along with even the skin being susceptible to negative effects, with higher exposure to certain irritating chemicals or particles causing outbreaks of acne, psoriasis and eczema. Conditions under the chronic obstructive pulmonary disease (COPD) bracket may arise, which includes bronchitis, chronic forms of asthma, pneumonia as well as emphysema. Rates of heart attacks may also go up, along with higher risks of strokes or arrhythmias, both of which can drastically shorten the life expectancy of those affected. Cancer rates can rise as well, particularly amongst individuals who live near areas that have ambient, or year-round carcinogenic pollutants accumulating in the air (such as near busy roads or certain industrial areas).

What causes higher levels of air pollution to occur in Song Phi Nong?

Some of the main causes of air pollution that are prominent throughout Song Phi Nong 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 Song Phi Nong, with all of these aforementioned factors coming together to cause the spikes in the pollution levels witnessed in Song Phi Nong.

Which people are most at risk of pollution-related illnesses in Song Phi Nong?

Whilst there are certainly more vulnerable members of the population within Song Phi Nong Chok, 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 can 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’s 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 Song Phi Nong 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 Song Phi Nong. 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.

When is the air most likely to be more polluted in Song Phi Nong?

The main causes of higher levels of air pollution in Song Phi Nong come predominantly, or more consistently, from vehicles, with a large number of cars, motorbikes as well as heavy-duty trucks and lorries all giving out pollution and noxious fumes, particularly if the fuel being used is of lower quality or the vehicle itself is worn down and aged. Other sources of air pollution present in Song Phi Nong include emissions from power plants and factories, road repairs and construction sites (as well as poorly paved roads also contributing to excessive amounts of dust and finely ground materials being thrown into the air), along with instances of smoke from the slash and burn farming sites being blown over Song Phi Nong from neighboring provinces and cities in the central region of Thailand. The use of fossil fuels in power plants, factories and other industrial sites can give off a variety of different pollutants, some of which will be mentioned in the following question regarding which types of pollution can be found in the air in Song Phi Nong. It is worth noting however that the more extreme spikes in air pollution are most likely to come from either natural disaster fires or man-made ones whereby vast swathes of forest or farmland are purposely set alight to clear crops and trees and return nutrients to the soil. Pollution from vehicles and factories can be considered as more ambient, or year-round causes due to them taking place throughout much of the year. Meanwhile, sudden fires can cause the PM2.5 and US AQI levels to skyrocket, and as such, they are the main concerns to watch out for in regards to the level of cleanliness in the air in Song Phi Nong.
