The bar chart gives information about the average daily minimum and maximum levels of SO2 and N2O being disposed of in four cities in the year 2000.

Overall, air pollution in Mexico results is higher than other three countries while air pollution in Los Angeles min sulphure dioxide is lover than other dioxides. However, in Calcutta figure all dioxide or oxide was similarly.

Focusing on the details, in Los Angeles figure min sulphure dioxide was low around 1 microgram while max sulphure dioxide was high than min sulphure dioxide around 9 microgram. However, min dinitrous oxide was 39 microgram but max dinitrous oxide was higher than other three micrograms about 104 microgram. Moreover, air pollution in Calcutta dioxides and oxides was similarly around 30-60 microgram.

Consequently, in Mexico air pollution was much higher than other figures, max sulphure dioxide and max dinitrous oxide was similarly higher approximately 200 microgram, but both of dioxide and oxide levels are low than two micrograms about 80-110 micrograms. However, in Beijing air pollution max sulphure dioxide was high roughly 130 microgram but other three micrograms was lower around 15-55 micrograms.
