Indian cities rank among the world’s most polluted, with a total of 21 listed in the world’s top 30 polluted regions in 2019, according to an air quality report.
This points out the important problem faced by India which has to be taken seriously in order to stop any further consequences to the people and the environment.
PM 2.5 are tiny particles in the air that reduce visibility and cause the air to appear hazy when levels are elevated. This can be noticed in last year in Delhi. People with breathing and heart problems, children and the elderly may be particularly sensitive to PM2.5. This led many people to wear (Including children) face mask to save them from the polluted air.
PM 2.5 includes pollutants such as black carbon, sulfate and nitrates. Exposure to such particles has been linked to lung and heart disorders and can impair cognitive and immune functions. Late last year, the spike in air pollution levels forced authorities, who termed the crisis as a public health emergency in Delhi. Many people have suffered from air pollution which even led schools to announce the holiday twice.
The report also points to India’s launch of the country’s first National Clean Air Program (NCAP) which aims to reduce PM 2.5 and the bigger particulate PM 10 air pollution in 102 cities by 20-30% by 2024 compared to 2017 levels.
