Warin Chamrap is showing some significant leaps in its air pollution levels in the early days of 2022, with sudden jumps in the US AQI readings being observed in late January, continuing into mid-February. Based on patterns from previous years, this is likely to continue for the next few months, although as with all pollution conditions, this can be subject to rapid change. Sudden strong winds and heavy rain can aid greatly in removing more prominent larger particles from the air as well as blowing away vast amounts of chemical pollutants and other air contaminants. To cite an example, in the second week of February 2022 a US AQI reading (which is a figure calculated using the volume of the several main pollutants present in the air, which will be elaborated on further in the article) of 172 was recorded, placing Warin Chamrap into the 'unhealthy' air quality rating bracket. The PM2.5 concentration at this time was found to be nearly 20 times over the World Health Organization's (WHO's) safe exposure recommendations. As such, whilst Warin Chamrap will not see such hazardous levels of air pollution present throughout the whole year, it can be subject to sudden spikes that can cause a great deal of harm to citizens as well as causing environmental damage, or even damage to buildings and other structures, with acid rain sometimes forming as a result of these chemical compounds entering into the atmosphere, although this is far less of an issue when compared to the damage it can cause to at-risk groups such as the elderly, young children, those with pre-existing health issues such as asthma, pregnant mothers and those with compromised immune systems.
Pollution levels in Warin Chamrap are most likely to have their highest readings appear towards the end of the year. Furthermore, the following early months of the next year also typically show significantly higher readings of air pollution in the form of the aforementioned US AQI and PM2.5 concentrations. This is based on readings taken from cities all over Thailand, a larger amount of them seeing consistent patterns each year. Although there are a few exceptions (with some cities seeing ambient levels of relatively high air pollution throughout the year, but lacking the dangerous spikes that are seen in the aforementioned times of the year), Warin Chamrap is most likely to see the higher air pollution levels at these times (the last few months of the year, typically starting around September, but potentially earlier, all the way through to the end of the year. Furthermore, the early months of the following year continue to see heightened pollution readings, with some of the highest figures of US AQI and PM2.5 cropping up from through to March or even April. As was mentioned, changes can always occur and air quality readings should be kept up to date, with these being available both on this page as well as the AirVisual app.
The main causes of higher levels of air pollution in Warin Chamrap 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 Warin Chamrap 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 Warin Chamrap from neighboring provinces and cities.
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 Warin Chamrap. 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 Warin Chamrap.
Health problems and side effects that may emerge when pollution exposure is high in Warin Chamrap include irritation to the respiratory tract, as well as infections of the lungs and throat. Skin conditions can occur from smoke and haze exposure, including atopic dermatitis and psoriasis. Further conditions include those that fall under the chronic obstructive pulmonary disease (COPD) grouping, with some instances including pneumonia, bronchitis, exacerbated forms of asthma as well as emphysema. More severe health conditions include arrhythmias, as well as inflated rates of heart attacks, strokes, all of which can inflate the early death rate within Warin Chamrap.
Some of the more prominent pollutants that can be found within Warin Chamrap as well as surrounding cities across Ubon Ratchathani province, or the Isan region, include ones that predominantly stem from the huge variety of combustion sources that take place throughout the year. These can include ones such as the nationwide issue of open burn fires (although of note this affects northern cities such as Chiang Mai far more, being considerably more prevalent in northern regions of the country as well as in other provincial areas that still have larger amounts of farmland present), combustion from vehicle engines as well as boilers in factories and other industrial sites. Some of the main pollutants released when any form of combustion takes place are ones such as volatile organic compounds (VOCs), as well as black carbon, along with other pollutants that go into calculating the US AQI aggregate. The chemicals used to calculate this US AQI figure include nitrogen dioxide, sulfur dioxide, carbon monoxide, ozone, as well as the two main forms of particle pollution, PM2.5 and PM10. Of these two, the smaller PM2.5 is well known as the far more dangerous, due to its minute size of 2.5 micrometers or less in diameter allowing it to bypass the bodies defense systems and lodge deep within the tissue of the lungs (with more on this being discussed in the following health issues question), with many health issues arising as a result when inhabitants of Warin Chamrap are exposed to excessive amounts of these hazardous particles present in smoke, haze and other clouds of pollution.
PM2.5 and some forms of PM10 can consist of materials such as water droplets and vapor, along with a variety of other liquids that can be aerosolized. Other materials include mold and fungal spores, bacteria, metals, nitrates and sulfates, along with finely ground silica dust, which can have a carcinogenic effect when inhaled. Some examples of the aforementioned VOCs include chemical compounds such as benzene, styrene, methylene chloride, toluene, xylene and formaldehyde. Their volatile nature allows them to maintain a gaseous state at much lower temperatures, thus making them much easier to breathe, and would be encountered prevalently around inhabited areas of Warin Chamrap, due to their discharge from everything from fires, cars, factories as well as even from household items. VOCs are one of the major sources of indoor air pollution and can emanate from products such as glue, paint, varnish, as well as aerosols such as deodorant, scented candles and other toiletries. These are some of the more prevalent air pollutants that may be found around Warin Chamrap, with certain areas such as busy roads and intersections that see a high level of rush hour traffic having higher concentrations of pollutants such as nitrogen dioxide, ozone and black carbon.
