The image contains a line graph titled "Sources of air pollutants in the UK from 1990 to 2005." The y-axis measures air pollutants in million tonnes from 0 to 8, increasing in increments of 2, while the x-axis shows the years from 1990 to 2005 in intervals of 3 years. Three lines, each representing a different source, show a decreasing trend over time. The top line starts at around 7 million tonnes in 1990 and ends at around 5 million tonnes in 2005. The middle line begins at approximately 5 million tonnes in 1990 and reduces to roughly 3 million tonnes in 2005. The bottom line initiates at about 2 million tonnes in 1990 and descends to approximately 1 million tonne in 2005.
