The bar graph represented the daily maximum and minimum levels of SO2,N2O which caused air pollution of four cities(Los Angles, Calcutta,Beijing,Mexico City) in 2000.
Overall, it is clear that Mexico city has maximum levels of N20 and SO2 amoung four cities and, Los Angles has lowest figure in SO2
Los Angles, the quantity of SO2 emitted in atmosphere around 2% which is different to other three countries. On the other hand, N20 is in the region of 104 which is slightly over to Calcutta and Beijing. In addtion, in Calcutta around 47% of air pollution of SO2 which is minimum Morever the minimum percentage of N2o in Calcutta is 30.
Moreover, Beijing produce minimum discharge of 14% N2O and 25% of SO2 amoung four cities. Whereas 207% of max N2O leaked in Mexico and 113% of Minimum.
To begin with that, Mexico figure out the air pollution ratio in Maximum SO2 was 200% and only 80% discharge the Min SO2 in 2000 at city atmosphere.
