1.Why Air pollution is very high in Delhi ?
According to World health organization, Delhi’s air quality is the worst of all 1650 cities ,it has surveyed.It damages lungs of 2.2 million children of Delhi annually and the effect is on the neighbouring districts also. On 25 November 2019, the Supreme Court of India made statements on the pollution in Delhi saying “Delhi has become worse than narak (hell)”. Justice Arun Mishra said that it is better to get explosives and kill everyone.The major sources of pollution in the city include according to the ministry of Earth sciences ;
Air quality index of Delhi is generally in the Good (0–50), Satisfactory (51–100), and Moderate (101–200) levels between March to September, and then it drastically deteriorates to Poor (201–300), Severe (301–400), or Hazardous (401–500+) levels during October to February due to various factors including burning of effigies during Vijayadashami, bursting of firecrackers during Diwali, stubble burning, road dust, vehicle pollution and cold weather. according to data released by environment ministry in 2022, the Air Quality Index of Delhi National Capital Region is over 200 for at least half the year.
Effect on Children: 2.2 million children in Delhi have irreversible lung damage due to the poor quality of the air. In addition, research shows that pollution can lower children’s immune system and increase the risks of cancer, epilepsy, diabetes and even adult-onset diseases like multiple sclerosis. Children are more vulnerable to the negative effects of air pollution as they are growing and developing which means that they breathe a higher rate of air per kilogram of their body weight. They also spend more time outside and are thus more exposed to it.
Effect on Adults:Poor air quality is a cause of reduced lung capacity, headaches, sore throats, coughs, fatigue, lung cancer, and early death. During the ongoing COVID-19 pandemic, in case the particulate matter is not controlled, the aerosols would work as virus carriers/host in the rapid spread of the pandemic.
