Prolonged exposure to pollution leads to acute respiratory infections and chronic bronchitis. It could also aggravate pre-existing heart and lung disease.

New Delhi: The worsening levels of air quality in Delhi is bound to bring its own share of problems, putting residents at the risk of developing heart-related issues and cancer. A week after Diwali night, the air quality has been deteriorating each passing day with a thick blanket of dense smog enveloping the city and nearby areas. Residents have been rushing to stores selling air masks and air purifiers are back in demand this season. A protest against the “ineffectiveness” of the government in tackling the rising pollution levels was also organised at Jantar Mantar on Sunday. Chief Minister Arvind Kejriwal cited farmers burning crop stubble in neighbouring states such as Haryana, Punjab and Uttar Pradesh as the reason for Delhi turning into a “gas chamber”.

But how does air pollution effect your health? Inhaling pollutants cause inflammation in the lungs and directly effects the heart and cardiovascular system. Particulate matter, when inhaled, pass into the blood stream and cause damage to the heart and blood vessels. Researchers at the American College of Cardiology noticed that ultrafine air pollutants decrease blood flow to the heart and its pumping function. Prolonged exposure to pollution leads to acute respiratory infections and chronic bronchitis. It could also aggravate pre-existing heart and lung disease. Asthma and reduced life expectancy are also linked to short-term exposure.

A study conducted by Green Peace earlier this year showed that there was a 13 per cent increase in PM 2.5 levels in India in comparison to a 17 per cent reduction in China from 2010 to 2015. Images taken by a NASA satellite showed that India’s air quality has steadily worsened during the five-year period, while China’s slight improved. The study also found that the average PM 2.5 levels in a year was 128 for New Delhi, much higher than China’s capital Beijing (81).
