The graph below shows different sources of air pollutants in the UK from 1990 to 2005. Summarise the information by selecting and reporting the main features, and make comparisons where relevant.

The line chart compares and contrast data on the change in the amount of polluted air released by the British’s transport, industry, total air pollutants and household over the 15-year period starting from 1990.

Overall, it is clearly that while the amount of air pollutants from transport witnessed an upward trend , there were a downward trend in the figures for the other three sources. In addition, the figure for total air pollutants experienced the most noticeable change during the research period.

Looking at the graph in more detail, in 1990, the amount of air polluted by household registered about 1 million tons, in comparison with roughly 7;5 and 1 millions of tons of the total air pollutants,industry and transport respectively. In the next 15 years, the figure for total air pollutants decresed considerablely to just under 4 million tons in 2005.

Similarly, the figure for industry also undergo a remarkable decline to 2 million tons after reaching a peak at approximately 6 million tons in the year 1990. Likewise, between 1990 and 2005, the figure for household dropped progessively from about 1 to 0.1 millions of tons. In contrast, the amount of polluted air produced by transport saw a gradual increase to the highest point at just over 1 million tons.
