The pie charts provide information on the sources of pollution and the primary pollutants in various cities in 2017. Overall, it is evident that most of the amount is filled by Carbon Monoxide. And, transportation is a leading factor for the contamination of the environment. Carbon Monoxide is accounted for just above half of the total pollutants with 51. 1%. There was a huge difference in proportion between the first and second, which is bagged by Sulfur Oxides with 16. 2%. The next prominent ingredients are Nitrogen Oxides and Volatile Organics had almost the same ratio with a little change of 0. 4% in the latter case. Meanwhile, Particulates had the lowest percentage of 7. 1%. In the case of problems that are responsible for its origin, Transportation led the race by a substantial margin of 49. 2%. This value got almost halved to 25. 3% for Stationary source fuel combustion. Fortunately, solid waste disposal recorded only 5. 5% that had the least effect on our ecosystem. Furthermore, the undocumented causes had a 7% hand in deterioration.
