The graph below shows the pollution levels in London between 1600 and 2000. Summarise the information by selecting and reporting the main features, and make comparisons where relevant.
The given line graph shows the amount of pollution caused by Sulphur dioxide and smoke, in London between 1600 and 2000. And is measured in micrograms per cubic meter. Overall, the pollution caused by Sulphur dioxide is always higher than the smoke.
In 1600, both pollution levels were low, and then, increased steadily. After a century, the pollution level of Sulphur dioxide rose to 700 micrograms per cubic meter, and the smoke rose to 200 micrograms per cubic meter. In 1850, the pollution levels of Sulphur dioxide reach the peak with about 900 micrograms per cubic meter. And the highest levels of pollution by smoke, occur around 1890, with nearly 500 micrograms per cubic meter. In the following years, both the pollution declined dramatically with fluctuation. And
in the year 2000, the pollution levels reached nearly zero.
It is visible, that the pollution levels were higher in the early 1900's than it is
currently
