The following line graph illustrates few major causes of air pollution and their trajectory in the UK from 1990 to 2005.
In hindsight, air pollution caused by industry has been decreasing considerably till the end of 2005 in comparison to other sources like households and transport which remain more or less the same over the years.
In 1990, pollution caused by industry was approximately 5.5 Million Tons(MT), which is particularly high in comparison to others pollutants. However, after a few short years we can see a major decline in the pollutants caused by industry which reached all-time low of 3 MT in 1996, declining steadily to 2 MT till the year 2005.
Coming towards sources like households and transport both causing around 1 MT of pollution in 1990 see a similar trajectory through the timeline with households also seeing upward trend in 1999 although an insignificant one. Towards the end of year 2005 we experience that pollution from remains the same at 1 MT but surprisingly pollution from households decreases to 0.2 MT approx. The air pollution from all sources combined was last recorded in 2005 being at 3.2 MT approx from the initial of 7 MT.
