An industrial site changes the fuel used in a heating system. Mean atmospheric pollutant concentrations near a metal-walled storage building are measured for the same length of time before and after the change. Weather conditions are similar during both measurements.
| Pollutant | Before the change in fuel (micrograms per cubic metre) | After the change in fuel (micrograms per cubic metre) |
|---|---|---|
| Sulfur dioxide | 48 | 7 |
| Oxides of nitrogen | 31 | 30 |
Compare the changes in the concentrations of sulfur dioxide and oxides of nitrogen.
Explain why the change in fuel should reduce damage by acid rain to the storage building but will not prevent it.
