A study done by WHO(World Health Organisation) about Air Quality show Indian cities have worst air quality not good to leaving . None of 168 Indian Cities Monitored by World Health Organisation not comply with the standards for Air Quality. Most urban areas of Indian cities are polluted are becoming death traps because of the high air pollution level .
India appears among the group of countries with the highest particulate matter (PM) levels. Also, its cities have the highest levels of PM10 and PM2.5 (particles with a diameter of 10 microns and 2.5 microns) when compared to other cities.
WHO monitored 1600 cities in 91 countries to check the air quality to represented by the annual mean concentration of fine particulate matter (PM10 and PM2.5, i.e. particles smaller than 10 or 2.5 microns)..The Database cover period from 2008 to 2017. Indian cities not comply with WHO Standards nor Central Pollution Control Boards Standards on air quality . Air Quality goes worst .
Indian Industries and Motor Vehicles contribute to the worst pollution. Indian government working on tackling air pollution. In Delhi, BS-VI or Euro VI Standards Quality Fuel introduced early in April 2018 that expected to come in 2020 .
WHO estimates that around 7 million people died in 2012 – 1 in 8 of total global deaths – as a result of air pollution exposure. The estimates confirm that air pollution is now the world’s largest single environmental health risk.
The new data reveal a stronger link between both indoor and outdoor air pollution exposure and cardiovascular diseases, such as strokes and ischaemic heart disease, as well as between air pollution and cancer.
Study Said :Severe haze is a major public health concern in China and India. Both countries rely heavily on coal for energy, and sulfur dioxide (SO2) emitted from coal-fired power plants and industry is a major pollutant contributing to their air quality problems. Timely, accurate information on SO2 sources is a required input to air quality models for pollution prediction and mitigation.
