The column chart compares the lowest and highest levels of Sulphur dioxide (SO2) and Dinitrous oxide (NO2), two air pollutants, in four cities, namely Los Angeles, Calcutta, Beijing and Mexico in 2000. Overall, the average presence of these two air polluting ingredients is much higher in Mexico than the other three cities.
As is presented in the graph, the level of Sulphur dioxide in the air of Los Angeles ranges from 1 to 10 which is remarkably lower than that of other cities. The presence of this air pollutant varies from 80 to 200 in Mexico which is the highest. The minimum level of SO2 is 47 in Calcutta and 25 in Beijing but the maximum range goes as high as 130 in Beijing which is more than double than that of Calcutta city. On the other hand, the presence of the second air polluting material, Dinitrous oxide, on an average, could be found more in the Mexico City’s air than any other city provided in the illustration. The minimum level of N2O in Mexico is 113 which is almost ten times higher than that of Beijing and approximately four times higher than that of Calcutta and Los Angeles. The upper level of N2O is Los Angeles is higher than the presence of N2O in Calcutta and Beijing.
In summary, the higher presence of Sulphur dioxide and Dinitrous oxide in Mexico reveal that air pollution in this city is worse than the three other cities.
