How to best protect from air pollution?

Reduce your air pollution exposure in Uthai Thani


Is it polluted in Uthai Thani and why does pollution occur?

Uthai Thani has seen some higher levels of air pollution present in years past, and will likely follow the same pattern over the next few years, with marginal improvements being seen depending on the severity of the pollution sources. In late September of 2021, a US AQI reading of just 21 was recorded, placing Uthai Thani into the 'good' air quality rating bracket, indicating the most optimal level of air quality. However, as readings from years past have indicated, September generally remains as one of the cleaner months of the year, and as each month passes the pollution levels typically start to rise, causing the air quality to decrease and more health risks make themselves present. Many of the main contributing factors in rising levels of air pollution in Uthai Thani are ones such as the exhaust fumes released from the various vehicles on the road. With cars, motorbikes, as well as heavy freight vehicles such as lorries and trucks in use on the road, they all compound the pollution situation and add to the overall PM2.5 and US AQI levels. It is not uncommon for many of these vehicles to be significantly aged, damaged, or in a poorer condition due to years of usage, which puts a greater toll on the environment due to the larger output of pollution released as a result of the poor combustion process that takes place within the engine.

Large amounts of oil vapors, hazardous particles and chemical compounds are released from these more aged vehicles, far more than what be seen emanating from newer or more environmentally-friendly models. Regarding the heavier freight vehicles contributing to motor-based pollution, many of these run on diesel fuel and can give off tons of microscopic rubber particles from the gradual wear and tear of tire treads. This can cause particle pollution to go up significantly, along with impacting the soil and the various ecosystems around it. Other sources of air pollution include dust from construction sites, road repairs, and even demolition sites (all of which can be a major source of particulate matter, far more than many people are aware of), along with the burning of trash, although this continues to be on the decline in more developed areas and mostly a continuing issue within certain provinces or far away from any major cities.

What health problems can be caused by breathing polluted air in Uthai Thani?

Exposure to high levels of air pollution in Uthai Thani can bring about all kinds of dangerous conditions, affecting certain individuals who fall into the sensitive group's bracket to a far more prominent degree. However, even healthy adults can succumb to the adverse effects of air pollution, particularly if exposure is excessive, or takes place over a longer time (such as for those who live near highly polluted areas like industrial areas, or near busy roads, causing the air to be of poor quality for a majority of the year). Many conditions that may arise as a result would be the typical short-term ones such as dry throat and coughs, as well as chest pains and mild infections of the respiratory tract. These can resolve quickly when exposure to air pollution is lessened or stopped altogether, and as such, they can be considered as more short-term or acute health issues. They may also develop into more long-term or chronic issues, with continuous chest infections and coughing leading to the scarring of lung tissue, which often results in permanently decreased lung capacity.

As well as this, the scarring or damage and inflammation to the tissue of the lungs can make one more vulnerable to a whole host of respiratory distress, with chronic obstructive pulmonary disease (COPD) presenting itself. This is an umbrella term that refers to a multitude of different lung and respiratory tract conditions, typically resulting in shortness of breath as well as making an individual at greater risk of severe damage from pollution exposure. Some further conditions that fall under the COPD bracket are one such as pneumonia, bronchitis, emphysema as well as asthma. Other forms of damage that can happen within the body include increased risk of cancer, heart attacks, strokes and arrhythmias, as well as ischemic heart disease and many other cardiac or pulmonary conditions that can bring about decreased quality of life in Uthai Thani, as well as lower life expectancy.

What are some of the types of pollution that can be found in Uthai Thani?

The main pollutants present in Uthai Thani would be the chemical compounds that form the US AQI reading, which is found anywhere that sees any forms of industrial activity, or combustion sources taking place. They are nitrogen dioxide, sulfur dioxide and ozone, or smog as it is better known when it gathers in larger amounts. The various oxides of nitrogen (NOx) that are also released by cars and combustion sources can undergo a chemical reaction and form ozone under the right conditions (higher exposure to sunlight), along with other gases and chemical compounds also adding to the formation of ozone. Other pollutants include black carbon, which is the main component in soot, and a potent carcinogen when inhaled, making it a very dangerous form of PM2.5 that also has climate-changing properties. Along with black carbon, volatile organic compounds (VOCs) are also formed from the incomplete combustion of both fossil fuels and organic matter. Some examples of VOCs are chemicals such as benzene, formaldehyde, styrene and toluene, all of which are extremely harmful to one’s health.

When is the air more polluted or dangerous to breathe in Uthai Thani?

Observing the PM2.5 levels collected for 2020 as reference points, it can be seen that Uthai Thani had its highest figures at the start of the year. Although fully calibrated data was missing from the first two months, March came in with a significantly elevated reading of 37.7 μg/m³, placing it into the 'unhealthy for sensitive groups' bracket, indicating that if data for the first two months were to be available, it would most likely also fall into this air quality classification. November and December also showed larger PM2.5 figures, indicating that the end of the year and the early months of the following year are usually when the pollution levels are at their worst in Uthai Thani.

When is the air cleaner and safer to breathe in Uthai Thani?

The cleanest period in which the air quality levels in Uthai Thani were recorded was between the months of June and October, with all of these months except June falling into the World Health Organization's (WHO's) target goal of 10 μg/m³ or less for the most optimal level of air quality. October came in with the most respectable reading at 6.3 μg/m³, indicating that the air would be significantly freer from haze, smoke and other polluting clouds of hazardous particulate matter or chemical contaminants.
