Air pollution in India is a serious issue, with the major sources being biomass burning, fuel adulteration, vehicle emission, and traffic congestion. Air pollution is also the main cause of the Asian brown cloud, which has been causing the monsoon season to be delayed. India is the world's largest consumer of fuelwood, agricultural waste, and ...
Air pollution in India is a serious environmental issue. [1] Of the 30 most polluted cities in the world, 21 were in India in 2019. [ 2 ] [ 3 ] As per a study based on 2016 data, at least 140 million people in India breathe air that is 10 times or more over the WHO safe limit [ 4 ] and 13 of the world's 20 cities with the highest annual levels ...
Awareness of air pollution problems was a factor in their decision to take action on a more environmentally favorable choice of transportation. Thus, the goal of Bound's project encapsulates whether the perception of risk associated with pharmaceuticals has an effect on the way in which medication is commonly disposed.
