The graph below shows UK air pollutants in millions of tons, from three different sources, between 1990 and 2005.

being released from various sources in Britain between 1990 and 2005.

Overall

, it can be observed that the highest proportion had emerged from the

Industry

,

whereas

,

Households

had the lowest ratio throughout the period.

To begin

with, the most striking feature of

this

graph is that in the initial term, the wind poison of

Industry

was around 5 million tonnes.

However

, in the proceeding year, a negligible decline can be seen.In 1996, a significant decrease can be observed in air pollution, which was approximately 2.5 million tonnes.

Moreover

, wind toxin in

Industry

were moderately reduced in 1999 and it becomes plateaued over the following years. The remaining information in

this

graph is that in 1990 the total atmosphere toxic waste reached their peak,

whereas

, transport and

households

had the same ratio.But in the year 1993, transport's atmosphere pollution increased by a negligible amount as compared to the

households

.

Furthermore

, the statistics for

industry

and transport diverged in 1996 (about 1 tonne and 0.8 tonnes, respectively).

However

, both had become slightly converged in 1996.Afterwards , the data of

industry

and

households

had become diverged and the proportion of transit had become parallel with the

industry

's data.
