Causes of Air Pollution in Delhi The capital of India is in the news for a very concerning reason – Air Quality Index. AQI is a parameter which measures the quality of air of a region. Delhi unfortunately is not faring well on the AQI scale. Albeit the AQI in some areas of Delhi has breached the 999 mark which is 9 times higher than the moderate range of 51-100. These are alarming statistics if you are a resident of the city. Breathing polluted air poses several health hazards especially to children and the elderly.

1. Crop Burning in Punjab Haryana and Uttar Pradesh: One of the primary reasons for poor AQI in Delhi is the burning of crops by farmers in neighboring states. Farmer’s burn the paddy left from previous harvest to make way for new plantations. It is a low-cost measure for clearing out fields. As the new planting season begins the paddy is burnt on a large scale causing a thick layer of smog over the Northern Plains including Delhi NCR. Each year almost 35 million tons of paddy is burnt in these states. This year the issue is even more severe due to wind blowing from Pakistan towards Central India which has brought the smog over from our neighboring country as well. 2. Pollution from Carbon Fuels: If you are a resident of Delhi or have ever visited the city then you must be familiar with Delhi’s traffic. Despite the availability of public transportation like the metro and local buses vehicular transport is a major source of air pollution in Delhi. Vehicular smoke and other gaseous emissions from the exhaust increase the presence of pollutants in the air and add to the pollution menace. As a last resort the Delhi Government has brought back the ‘odd/even’ scheme from the last year to reduce traffic and hence contain the emission of harmful pollutants. Cab Services like Ola and Uber have also forgone their surge pricing policy to help the city get out of its predicament. Despite these measures vehicular emissions still contributes to a major portion of air pollution in Delhi. Causes of Air Pollution in Delhi NCR:-

3. Onset of Winters: Weather conditions also worsen the AQI. As winter sets in air molecules become heavy and dense. The cool air remains close to ground hence locking the pollutants in and around the cityscape. A lack of strong winds then causes the Delhi’s notorious smog cover. While the change of seasons has always caused some change in air quality the presence of excessive pollutants has worsened the situation. 4. Infrastructure and Real Estate Construction: Sometimes development too comes at a cost. Construction in the region of Delhi NCR is also causing the decline of AQI in Delhi. Fine dust from construction activities is perceived as a major contributor to the toxic mix of smog. Keeping that in mind the government and Supreme Court of India have banned all construction activities in Delhi NCR for now. Moreover cement factories and coal fired brick kilns in the neighboring states have also been shut down in an attempt to curb the air pollution in Delhi NCR. 5. Residual Pollutants from Diwali

The Festival of Lights is celebrated with much vigor across the country. But it has also become a health hazard for Delhiites. Residual smoke from firecrackers increases the number of toxic metals in the air. The heavy smog means the metals can hang in the ambient environment for days further worsening the AQI and breathability of Delhi’s air. While the government had taken steps to reduce toxic smoke from firecrackers by developing green alternatives the measure was far from effective – at least this year. Air purifiers cleanse the air in your homes offices schools and other indoor spaces where groups of people are breathing in the same polluted air. Air purifiers with the right air filters can ensure that your health and well-being is not compromised. More importantly these units can bring veritable relief for people suffering from conditions like Asthma and lung infections.
