The given line graph describes various reasons causing air pollution in the UK between 1990 and 2005.
Overall, the air pollution due to all industries is decreasing linearly over the span of five years. Transportation, industry, and household sources contribute to air pollution, with the latter having a zigzag pattern.Pollution caused by industry, on the other hand, is steadily decreasing.
Initially, pollution from industry (5 million metric tons) was greater than pollution from transportation and households.Up until 1993, there was a slight decrease in pollution due to industry.There was a steep decrease in pollution from 1993 to 1996, and the slope of decrease has since slowed until 2005.
However, pollution from households and transportation was 1 million metric tonnes in 1990, but the trend later experienced many ups and downs.Following this zigzag pattern, from 1999 to 2005, pollution caused by transportation was strictly increasing, while it was strictly decreasing for household use.
All in all the total pollutants emitted in air have decreased from 7 million tonnes to 4 million tonnes till 1999 with constant slope. Thereafter from 1999-2002 the slope has decreased. Later from 2002-2005 the slope of decreasing has become greater and finally got a minima of 3 million tonnes of total air pollutants.
