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

The line graph illustrates the amount of

air

polluted by

Industry

, Transport and

households

over 15-year timescale spanning from 1990 to 2005 Broadly, the popularity of

air

pollutants caused by

Industry

and

Households

registered downward trends,

while

that of Transport witnessed completely opposite trends. Notably, the total

air

polluted in three different sources saw a sharp decrease during the surveyed period From the outset in 1900, the pollution of

air

produced by

Industry

accounted for almost 6

million

tonnes

, which was nearly 5

million

tonnes

than that of

Households

. The figure for

Households

remained steady in the following 9 years before declining to under roughly 0

million

tonnes

in 2005, whilst the amount of

air

created by

Industry

also

saw a dramatic fall to about 2

million

tonnes

in the initial year Commencing from 1900, exactly 1

million

tonnes

of

air

pollutants originated from Transport, but it

then

fluctuated to approximately 1,2

million

tonnes

in 1999 before rising significantly, with 3

million

tonnes

in 2005
