The toxic levels of air pollution in and around Delhi pose a serious threat to humans, and the surrounding environment. Adding to the severity, changing weather patterns have trapped pollutants in the air, exacerbating the situation. Doctors are warning people about the dangers of going outside and discouraging them from doing so.
What is causing excessive air pollution in Delhi?
The national capital is bordered by the states of Haryana and Uttar Pradesh.
1: Crop burning by farmers in these states is one of the primary causes of rising air pollution levels in Delhi.
2: Pollution caused by Delhi's traffic jams is another factor contributing to air pollution and smog. The air quality index has risen to a "severe" level.
3: Vehicle emissions exacerbate the dangers of air pollution and smog.
4: As the winter season approaches, dust particles and pollutants in the air become immobile. Because, of stagnant winds, these pollutants become trapped in the air and affect weather patterns, resulting in smog.
5: Overcrowding in the capital is another source of air pollution.
6: Another source of air pollution is a lack of investment in public infrastructure. In India, investment in public transportation and infrastructure is low, resulting in congested roads and, as a result, air pollution.
7: Large-scale construction in Delhi-NCR is another source of dust and pollution in the air. As a result of the deteriorating air quality, a number of construction sites have halted operations, as directed by the Delhi Government.
8: Industrial pollution and garbage dumps also contribute to air pollution and smog formation.
9: Despite the cracker ban, firecrackers were everywhere this Diwali. It may not be the primary cause of the smog, but it certainly contributed to its accumulation.
Case Analysis on air pollution in Delhi!
Air pollution events have become a major source of concern in recent years, as their frequency and intensity have increased over time. Every year, from late October to the end of November, some parts of India experience an alarmingly high level of air pollution.
Which areas of Delhi are highly susceptible to air pollution?
The air quality in Narela, Delhi University, AnandVihar, India Gate, and Dwarka was extremely poor. Ghaziabad, Noida, Greater Noida, Gurugram, and Faridabad had AQIs of 285, 320, 294, 315, and 310, respectively. Poor air quality has been reported in areas such as Cyber Hub and Najafgarh as well.
Levels of AQI
According to CPCB data, an AQI of 0-50 is considered good, 51-100 satisfactory, 101-200 moderate, 201-300 poor, 301-400 very poor, and 401-500 severe.
However, over the last few years, the AQI in Delhi has been as follows:
326 in 2022, 391 in 2021, 414 in 2020, 337 in 2019, 281 in 2018, 319 in 2017, and 431 in 2016.
After Diwali, Delhi's air quality was very poor,' but it was still better than in previous years.
The air quality in Delhi on the morning after Diwali was classified as "very poor," but the situation was better than in previous years due to favourable meteorological conditions, which prevented pollutants from accumulating quickly.
The fact that the air quality was slightly better the morning after Diwali,does not imply that it is good air.
PM-2.5 particles are fine particles with a diameter of 2.5 microns or less that can travel deep into the respiratory tract, reaching the lungs and entering the bloodstream. Despite the fact that firecrackers were set off in several parts of Delhi despite a ban, the intensity appeared to be lower than in the previous two years.
