The line graph given here shows the different sources of air pollution in the UK from 1990 to 2005.
From the graph we can say that overall air pollution levels have been decreasing, the industry has been a major contributor to air pollution while household has contributed the through the years.
Air pollution caused by the industry has steadily declinied in the 90s decade by approximately 4 million tone, moreover there is decline even after the year 1999 but it is not as steap as before.
The total number of pollutants emitted into the air gradually reduced to about 5 million tonnes by 2005. Further, the industry with the highest amount of contaminants with 5.5 million tonnes in 1990 gradually declined to about 2 million tonnes in 2005. Although the figures for transport and household emissions were equal at the beginning of the period, there was a slight increase in the number of air pollutants from transport to 1 million tonnes by 2005, meanwhile the household emission dropped to a negligible level at 0.1 million tonnes at the end of the period.
