In a recent episode of Aaj Ka AQI, Newslaundry took a closer look at air quality in India. They visited the Ministry of Environment, Forest, and Climate Change (MoEFCC) to discuss air pollution issues.
At the Lodhi Road monitoring station, the Air Quality Index (AQI) was measured at 161, which falls in the ‘moderate’ category. However, a portable air quality monitor used during the show recorded a concerning 336, indicating ‘very poor’ air quality. This disparity highlights the challenges of accurately gauging pollution levels in urban areas.
A report by the Center for Research on Energy and Clean Air (CREA) revealed troubling facts about air pollution in India. It found that up to 42% of the nation’s PM2.5 particles—tiny pollutants that can harm health—are produced chemically in the atmosphere. This chemical formation is largely due to emissions from coal-fired power plants (CFPPs), particularly sulfur dioxide (SO2), rather than just from vehicles or agricultural practices like stubble burning.
Interestingly, while India is the largest source of SO2 emissions, around 78% of coal power plants are not required to install flue gas desulfurization (FGD) systems. These systems help to reduce SO2 emissions, so their absence is a significant gap in pollution control. The reaction of SO2 with ammonia in the air results in ammonium sulfate, making up anywhere from 17% to 42% of PM2.5 mass across various Indian states, with many showing a range between 30% and 40% annually. This means that secondary particulate matter plays a critical role in the country’s air pollution crisis, rather than being a minor issue.
To tackle these concerns, the MoEFCC is pushing for the installation of FGD systems in coal-fired power plants. This step is crucial in the fight against air pollution and could significantly improve air quality.
Interestingly, social media discussions around air pollution have surged, with many users sharing personal experiences of health issues linked to poor air quality. There is a growing push from communities calling for stronger regulations on industrial emissions.
Additionally, research by the World Health Organization indicates that air pollution can lead to severe health issues, including respiratory diseases and heart problems, affecting millions.
Improving air quality requires concerted efforts from both the government and communities. The situation is urgent, as clean air is vital for health and well-being.
