The graph below shows different sources of air pollutants in the UK from 1990 to 2005. Summarise the information by selecting and reporting the main features, and make comparisons where relevant.

The linear graph exemplifies the several sources of

air

pollutants

expressed in

million

tonnes

in the United Kingdom from the

year

1990 to 2005.

Overall

, the number of

air

pollutants

released from the industry is much higher than other

pollutants

.

Moreover

, there is a significant fall in the total amount of

pollutants

from all the sources. In the

year

1990, around 7

million

tonnes

of

air

contaminants were emitted from all different sources which significantly dropped to approximately 4

million

tonnes

by the

year

1999 and

then

continued to fall to about 3

million

tonnes

at the end

of the period. The total amount of

pollutants

emitted into the

air

gradually reduced to 5

million

tonnes

by 2005.

Further

, the industry has the highest number of contaminants with 5.5

million

tonnes

in 1990 gradually declining to 2

million

tonnes

by the

year

2005. Despite, transportation, and households the same amount of emissions in the

year

1990 but

thereafter

there was a slight increase in the number of

pollutants

from transport by 1

million

by the

year

2005,

while

household emissions dropped to a negligible level of 0.1

million

tonnes

at the end

of the period.
