Answer 1

Answer:

Explanation:

It is often difficult to measure air pollution in the field, as often sophisticated equipment and long-term monitoring are needed to obtain worthwhile data. One way to overcome this problem is to choose an aspect of air pollution which can easily be measured and combine it with secondary data available on the Internet.

Particulate pollution (i.e. soot) adhering to tree bark can rapidly be measured using nothing more complicated than sticky tape. Immediately this introduces a number of variables, which could be investigated, such as the direction in which the bark is facing, its height off the ground and its distance from a point source of pollution.
