The line graph depicts data of United Kingdom, highlighting the origin of air impurities in a span of fifteen years. The features are represented in million tones.
Overall, the sum in air tainting and the contaminants released by factories had the bigger trends, compared to emmisions from vehicles and households in the reprensented duration.
To begin with, its clearly illustrated, total air pollution not only took the first position but also most trended high during the whole period. Despite, its significant decrease at the end of the graph, in 1990 its soar was seven million tones which was the highest during beginning the 12th month period. Second in position, was fouling from industrial areas starting with approximately more than five million tones, after which it experienced substantial decrease hitting the bottom in later year accounting for 2-million.
On the other hand, at the third position was violation of air originating from sources of convey. It experienced a steady flow throughout the period with no rise of above one million tones. As far as concerned, impurities from houses was not only the least trend but also experienced no major changes in the years, as it remained steady with its proportion more or less than half a million tones.
