Presentation of airpolution made during the project meeting in October 2012

1. Research of air pollution with
Sulfur dioxide

2. Goal
• Evaluating pollution of sulfur dioxide by using
Rhytisma acerinum fungus.

3. Course of Work
1. Chose a maple tree and collect as many
leaves as they would cover 1 m² area.
2. Count spots of fungus Rhytisma acerinum on
1m² of leaves.
3. Calculate leaves
spottiness.

4. We are collecting leaves for the
experiment.
