Qualité de l’air à Sam Ngao

Is there air pollution present in Sam Ngao?

Sam Ngao has shown some elevations in its pollution levels through certain months of the year, and this becomes more of a prominent issue towards the end of the year, as is a common theme throughout many areas of Thailand. This is largely due to smoke and haze caused by open burn fires, as well as many other reasons that will be touched on in the following question. In early December of 2021, US AQI readings of 99 were recorded, placing Sam Ngao into the higher end of the 'moderate' air pollution rating bracket. This is only a few units away from being moved up to the 'unhealthy for sensitive groups' bracket, which requires a US AQI reading of 101 to 150 to be classified as such. At the time in which the above-mentioned reading of 99 was taken, the PM2.5 levels were found to be at a rather large concentration of 35 μg/m³, approximately seven times higher than the safe annual air quality guidelines set out by the World Health Organization's (WHO's) standards. As such, the air in Sam Ngao at this time of the year may present health issues for many different people living in the vicinity. The question at the end of the article will delve further into which groups are most at risk. Preventative measures during periods of higher air pollution (with days before the above-mentioned figure coming in even higher with readings of 122 and 127) include wearing fine particle filtering masks, avoiding outdoor activity if possible, especially if it is strenuous such as jogging or other forms of exercise, as well as closing doors and windows to prevent indoor air pollution levels from rising.

Why is the air in Sam Ngao polluted?

As touched on briefly, the issue of open burn fires, of slash and burn farming practices affect many areas throughout Thailand, with the northern regions being hit a lot harder, as well as being subject to smoke drifting over the border from neighboring countries. However, there are also many other causes of air pollution present, and whilst smoke emanating from fires may make its way over to Sam Ngao (with the smoke from these fires being able to travel great distances and pollute areas many miles away), it still stands to reason that there are many other sources of air pollution present. These include ones such as fumes from vehicles, as well as other emissions from factories, power plants and any other industrial sites that utilize fossil fuels to obtain their power. Poorly paved or badly maintained roads can lead to dust and fine particle buildup, along with construction sites (as well as demolition sites) also contributing to increased amounts of smoke, smog and pollution in the air.

What are some chemicals that can be found in the smoke and haze in Sam Ngao?

Some pollutants that may be found in the air in Sam Ngao include ones such as black carbon and volatile organic compounds (VOCs). Due to both being released from the burning of both organic material as well as fossil fuels, they can be found prominently in many areas that see any level of industrial activity, or in more simple terms anywhere that has some form of burning or combustion taking place. Black carbon has many dangerous properties when inhaled, as well as also having warming effects on the environment. Some examples of VOCs include benzene, styrene, toluene and formaldehyde, all of which come with negative side effects when inhaled, which is made easier due to their volatile nature helping them maintain a gaseous state even at lower temperatures.

Is it unhealthy to breathe polluted air in Sam Ngao?

Whilst there are many times during the year when the air quality in Sam Ngao is considerably better and thus the likelihood of adverse health issues occurring is greatly lessened, during bouts of higher air pollution there are many health problems that can arise. These include ones that fall under the chronic obstructive pulmonary disease (COPD) bracket, namely asthma, bronchitis, pneumonia and emphysema. Skin irritation can also occur, along with mucous membranes being aggravated. More serious health issues include increased risk of heart attacks, arrhythmias, strokes and premature death are all possible when pollution exposure is sustained at a high enough level over time.

Who is most vulnerable to breathing polluted air in Sam Ngao?

Those that are most vulnerable to breathing smoke, haze and clouds of fine particles in Sam Ngao are groups of people such as the elderly. Older members of society as well as those visiting or passing through are generally more susceptible to the negative side effects brought on by breathing pollution, due to increased sensitivity towards respiratory issues, as well as cardiovascular ones, with these two systems (pulmonary and cardiac) being the most susceptible to harm. What may begin as normal upper or lower respiratory infections brought about by a combination of pre-existing health conditions, coupled with potential co-morbidities from sedentary lifestyles or habits such as smoking, these infections can worsen and turn into possibly fatal conditions. Due to this factor, elderly people should maintain good standards when it comes to reducing their pollution exposure. The information and forecasts available on this page, as well as the AirVisual app, can aid greatly in informing individuals as to when the air quality levels become hazardous, or at least to a level where they may start to aggravate respiratory or cardiac conditions amongst certain members of the population. Of note is that whilst there is definitively a link between higher levels of pollution and more severe health conditions as a result of exposure to these higher levels, any level of air pollution has the potential to cause harm, and as such mild elevations in US AQI readings, as well as PM10 or PM2.5 levels, should be acted upon accordingly. Other groups that fall into the more at-risk bracket are those such as young children, babies as well as pregnant mothers. Babies and young children are still undergoing their vital formative years, and due to many pollutants being able to cause alterations to the nervous system, as well as damage the lungs and other organs in the body, young children could potentially experience stunted growth, stunted mental development as well as seeing increased cases of health issues such as asthma, which can stay with them for life. Other groups that also fall into the more vulnerable bracket include those with compromised immune systems, often going hand in hand with the aforementioned pre-existing health conditions, as well as those with hypersensitivity towards certain particles or chemical compounds. Pollution readings recorded towards the end of the year in 2021 certainly indicate that there is potential for adverse effects to occur, not only amongst these more at-risk groups but also amongst the general population.
