Karol Bagh has shown some significant spikes in its air pollution levels, both recent as well as in times past, and will likely continue to do so until significant changes have been made and more stringent rules and regulations implemented. In late January of 2022, US AQI readings of 168 were recorded, placing Karol Bagh into the 'unhealthy' air quality rating bracket, which can be a significant health risk for the whole population. These readings rose rapidly up to a figure of 251, putting Karol Bagh into the second-worst rating of ‘very unhealthy’, and even more alarmingly, in late December of 2021, readings that met the hazardous air quality rating were recorded, indicating that at that particular time the air in Karol Bagh would be permeated by thick clouds of smoke in certain areas, along with noxious oil vapors, hazardous clouds of particulate matter, along with smog, haze and other coalesced pollution. As such Karol Bagh can be considered to have seriously dangerous levels of air pollution present through some months of the year, and caution should be practiced amongst those living there or passing through.
Pollution levels in Karol Bagh are elevated due to a variety of different sources all contributing to the elevated readings seen in both the past and the ones that will continue to crop up in the future. Many of them release their unique pollutants in the forms of smoke, haze and clouds of hazardous fine particulate matter. Along with certain ones that are unique to industrial processes or other polluting causes, there are also ones that are broader and tend to be released from many if not all of the polluting sources. The chemicals released from these sources will be discussed further in the article. For now, Karol Bagh has its pollution coming prominently from industrial sites, factories, and other businesses (both large and small scale) that have a form of combustion taking place to provide energy. Any form of combustion can release large amounts of pollution into the air, and if these procedures are not handled with strict protocol (which is more common in certain areas that have less stringent measures in place), much larger amounts of dangerous pollution can escape into the air and drive the PM2.5 levels as well as the US AQI readings up. Karol Bagh is known as an industrial city, and as such the burning of fossil fuels such as coal, oil, natural gas and diesel can be major contributing factors. Furthermore, due to having a fairly large population that sees continued vehicle ownership, cars, motorbikes and other smaller personal vehicles would also release large amounts of pollution in the air, more so if they are of the aged or poorly maintained variety, or if lower quality fuels are used in their engines. Larger or more heavy-duty freight vehicles such as trucks, lorries and even buses can release many tons of soot and other particles into the atmosphere, with a fair amount of these vehicles still utilizing diesel as their main fuel source. The continual wear and tear of tire treads can also cause tons of finely ground rubber particles to enter into both the air, bodies of water and the earth, over long periods, which can have a harsh effect on both the surrounding wildlife outside of the city limits, as well as contaminating water sources, entering into the food chain and causing breathing problems amongst those that are exposed to these fine particles (amongst many other PM10 and PM2.5 pollutants present throughout Karol Bagh).
Continuous exposure to higher concentrations of pollution in the air in Karol Bagh can cause many dangerous or adverse health conditions to occur, being of particular prominence to certain individuals who are part of the sensitive group demographic, also covered later in the article. Despite certain groups being more at risk, it is well-known that even healthy or physically fit adults may find themselves on the receiving end of the negative side-effects caused by polluted air in Karol Bagh, particularly if this exposure is of a higher magnitude or takes place over a longer period, a factor that may be very important to note for those that find themselves living near to much more highly polluted areas such as industrial districts or near busy roads, whereby the air quality will be poorer, and hazardous particles more prevalent in the atmosphere for much of the year. A larger number of ailments can present themselves amongst inhabitants, as a result, would more common short-term conditions such as dry or sore throat with accompanying cough, as well as chest pain and mild infections of the respiratory tract. These can usually get better on their own accord once pollution exposure is halted or lessened. These count as some of the less serious but more common health issues within Karol Bagh. With continuous air pollution exposure taking place, respiratory aggravation may also develop into more long-term, chronic health problems. The continuous chest infections sustained as well as the accompanying coughing can lead to the scarring of lung tissue, which can result in a significantly (and often permanent) decreased lung capacity. Furthermore, the scarring and damage sustained to the tissue of the lungs can cause one to become more vulnerable to a whole host of respiratory ailments, with chronic obstructive pulmonary disease (COPD) typically showing itself in one form or another. A few examples of the different forms of COPD, which usually cause reduced lung capacity, shortness of breath and greater susceptibility to further respiratory complications. Some examples of illnesses that fall under the COPD bracket are pneumonia, bronchitis, emphysema and 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 as well as lower life expectancy in Karol Bagh.
Groups that are most at risk to higher pollution levels in Karol Bagh include those that are young and still undergoing vital developmental stages, so children and babies will be highly susceptible to health conditions such as stunted growth and the appearance of potentially lifelong health problems such as asthma. Others include those that live near areas that have higher levels of air pollution present such as busy roads, industrial sites or other areas where open burning or higher occurrences of combustion take place. The elderly, pregnant women and those with compromised immune systems can all be considered as far more vulnerable to the damaging effects of air pollution in Karol Bagh.
Some pollutants that may be found prominently in the air throughout Karol Bagh include those that go into forming the US AQI figure, which are nitrogen dioxide, sulfur dioxide, ozone, carbon monoxide and the two main forms of particle pollution, PM10 and PM2.5. The latter of these two is far more dangerous, with its minute size of 2.5 micrometers or less in diameter giving it the ability to penetrate deep within the tissue of the lungs and even pass through the blood barrier and enter the circulatory system. Some materials that make up the PM2.5 and PM10 collective include dust, sand, finely ground silica particles, microplastics, liquid or oil vapors, along with mold, fungi and certain bacteria. These are some examples of pollutants that can be found in the atmosphere within Karol Bagh, varying in their amounts depending on the location.
