Study of adaptations of city flora to smog

Introduction:

Harmful effects of smog on human and other animals is well known. Smog in many cases has resulted in death and serious illness with symptoms such as aching lungs, wheezing, coughing and headaches. While smog has serious harmful effects on animals, we are not sure how it affects other organisms, especially plants. 

 
 Project description:
In this project you will design and perform experiments to discover the effect of smog on plants. You may also gather information or study on plants that exist in polluted areas and compare them with similar plants in clean air.
