How serious is Delhi Air pollution?

Delhi's air pollution is a very serious issue that poses a significant health risk to its residents, particularly in terms of respiratory and cardiovascular diseases.
The air quality in Delhi is often severely polluted, particularly during the winter months when cold temperatures and low wind speeds combine with a high concentration of pollutants in the air, such as particulate matter (PM2.5), nitrogen oxides (NOx), and sulfur dioxide (SO2). These pollutants can cause a range of health problems, including lung cancer, chronic obstructive pulmonary disease (COPD), asthma, and other respiratory and cardiovascular diseases.
While it is difficult to attribute specific cases of lung cancer solely to air pollution, studies have shown a strong correlation between exposure to air pollutants and an increased risk of lung cancer. One study conducted by the World Health Organization (WHO) estimated that outdoor air pollution was responsible for 4.2 million premature deaths worldwide in 2016, with lung cancer being a significant contributor to this mortality.
In summary, Delhi's air pollution is a severe issue that poses a significant health risk to its residents, and exposure to air pollutants is associated with an increased risk of lung cancer and other respiratory diseases. It is essential for policymakers to take action to reduce air pollution levels and protect public health.
