The provided graph analyses the findings of a 1990-2005 statistic conducted on three factors creating air pollution in the UK, to explore their proportion.
Overall, the data reveal considerable disparity in which Industry was consistently the highest and the opposite was true for Households. Additionally, with the exception of Households, the rest experienced a downward trend.
Commencing with approximately 5 million tonnes, Industry was the major contributor to air pollution, experiencing a significant plunge, hitting the final lowest with around 2 million tonnes, maintaining this rank despite decreasing. Following the first, Transport started with 1 million tonnes which was the same as Households. However, while the former remained relatively stable at the initial value during the survey period, becoming the least significant producer of air pollutants, the latter descended minimally , preserving the lowest position with a humble 0,1 million tonnes by 2005.
Consequently, due to these fluctuations of three contaminators, the total air pollutants largely show a clear correlation with the three, which began with more than 7 million tonnes and finalized with roughly 4 million tonnes
