air-pollutants

  2. You must include an overview
  3. You must compare the data

bar-chart-air-pollution

FOUR-PARAGRAPH STRUCTURE

  1. Introduction + Overview
  2. Body 1
  3. Body 2
  4. Conclusion (similar to overview)

1. Introduction – paraphrase

The chart shows the average daily minimum and maximum levels of air pollutants in 4 big cities in 2000

SAMPLE – “The chart displays the peak and minimum levels of sulphur dioxide and nitrous dioxide, measured in micrograms per cubic metre, on a typical day in four major urban centres.

TIP – If you write the units in the intro (e.g. micrograms per cubic metre) you don’t need to repeat them every time you write a figure.

2. Overview – summarize the main points

SAMPLE – “From the chart it is clear that Mexico City has by far the highest level of pollutants overall, while the other cities have some similarities and differences in the level of pollutants in their atmospheres.”

3. Body – make the overview clear with specific details

NOTE: try to give each paragraph a clear topic. In this example, the first body paragraph is about N2O levels, while the second is about SO2 levels.

SAMPLE – “Mexico City’s peak N20 level is 207, which is twice as high as the level in Los Angeles and four times higher than the levels in Calcutta and Beijing. Similarly, the minimum N20 level of 113 in Mexico City was 8 times higher than Beijing, which was the city with the lowest minimum N2O level, while its N20 level was 3 and 4 times higher than those of Los Angeles and Calcutta.

“With respect to SO2 levels, Los Angeles has the lowest average high and lows by a significant amount. Peak SO2 levels in Los Angeles in 2000 were only 10, which was 6 times lower than the next city: Calcutta. At the other end of the scale, peak SO2 levels in Beijing were 130, while in Mexico City they were even higher at 200. Los Angeles also had the lowest minimum at just 2, making it 40 times lower than Mexico City’s minimum. Interestingly, Beijing’s low was 25, which was only half of Calcutta’s, despite Beijing having a much greater maximum. (235 words)

NOTE – this sample is already over 200 words so it is not necessary to write a conclusion. The overview is the key part. If you prefer, you can also write your overview at the end as a conclusion (just don’t repeat yourself). Take a look at the TWO full answers below.

FULL ANSWER 1 (Intro-Body-Overview)

The chart displays the peak and minimum levels of sulphur dioxide and nitrous dioxide, measured in micrograms per cubic metre, on a typical day in four major urban centres.

Mexico City’s peak N20 level is 207, which is twice as high as the level in Los Angeles and four times higher than the levels in Calcutta and Beijing. Similarly, the minimum N20 level of 113 in Mexico City was 8 times higher than Beijing, which was the city with the lowest minimum N2O level, while its N20 level was 3 and 4 times higher than those of Los Angeles and Calcutta.

With respect to SO2 levels, Los Angeles has the lowest average high and lows by a significant amount. Peak SO2 levels in Los Angeles in 2000 were only 10, which was 6 times lower than the next city: Calcutta. At the other end of the scale, peak SO2 levels in Beijing were 130, while in Mexico City they were at 200. Los Angeles also had the lowest minimum at just 2, making it 40 times lower than Mexico City’s minimum. Interestingly, Beijing’s low was 25, which was only half of Calcutta’s low, which was not far below its peak.

From the chart it is clear that Mexico City has by far the highest level of pollutants overall, while the other cities have some similarities and differences in the level of pollutants in their atmospheres.

FULL ANSWER 2 (Intro-Overview-Body)

The chart displays the peak and minimum levels of sulphur dioxide and nitrous dioxide, measured in micrograms per cubic metre, on a typical day in four major urban centres. From the chart it is clear that Mexico City has by far the highest level of pollutants overall, while the other cities have some similarities and differences in the level of pollutants in their atmospheres.

Similarly, the minimum N20 level of 113 in Mexico City was 8 times higher than Beijing, which was the city with the lowest minimum N2O level, while its N20 level was 3 and 4 times higher than those of Los Angeles and Calcutta.

With respect to SO2 levels, Los Angeles has the lowest average high and lows by a significant amount. Peak SO2 levels in Los Angeles in 2000 were only 10, which was 6 times lower than the next city: Calcutta.
