Lichens do not grow around cities because pollutants such as sulfur dioxide quickly destroy a lichen's?

That's not always true, some lichens are indeed sensitive to pollutants such as sulphur dioxide and will therefore not grow in highly polluted areas. However some lichens thrive on certain pollutants and therefore will grow very well in highly polluted areas (cities).

What plants are sensitive to sulfur dioxide?
LICHENS
Why do governments monitor emissions of sulfur dioxide and nitrogen oxides?
Because they are major pollutants that contribute to acid rain.
How lichens indicate pollution?
lichens are sensitive to sulfur dioxide, they are biological indicators. The cleaner the air the more lichens will grow. Therefore if there are houses right by a road, if you look on the roof there would be less lichens as there would be more sulfur dioxide in the air because of pollution. Hope this helps By Troy Flynn
What pollutants does transportation cause?
carbon dioxide, carbon monoxide, nitrogen dioxide, acetone, formaldehyde, ...
What are three main types of air pollutants in the United States?

What pollutants are pollutants in the air because of human activity?
the answer to this question is pretty simple and it primary pollutants
What gas are lichens sensitive to?
Lichens are sensitive to Sulphur dioxide and nitric and nitrous oxides as well as ammonia. Pollutants.
Why are nitrogen dioxide and acid rain called secondary pollutants?
Because they are only caused or formed by pollutants that existed before.
What plants are sensitive to sulfur dioxide?
LICHENS

What pollutants is a brown gas nitrogen dioxide sulfur dioxide carbon dioxide nitric dioxide?
Nitrogen Dioxide
Lichens can be used to estimate levels of pollution from?
Sulfur dioxide
What effect does sulfur dioxide have on lichens?
your nans fanny crack
When do lichens grow?
Lichens need sunlight, water, nutrients from the air including dust and some nutrients from the substrate they grow on they are sensitive to sulfur dioxide there are fluffy lichens, crusty lichens, scaly lichens, leafy lichens etc
How can you protect yourself from pollutants like carbon dioxide?
tree planting because when we inhale we got oxygen and when we exhale we produces carbon dioxide which the plants needed.
Why do governments monitor emissions of sulfur dioxide and nitrogen oxides?
Because they are major pollutants that contribute to acid rain.
How do scientists use lichens as detectors?
Lichens lack an outer impermeable layer that would protect them from pollutants. Various species find it impossible to live in regions with high concentrations of sulphur dioxide or heavy metals. Others actually favour high concentrations of nitrogen in the form of ammonia. Therefore, by looking for the presence of lichens in ecosystems scientists can try to understand which pollutants might be present. They might, for example, expect to find a certain lichen in combination with certain rocks, climate patterns and other plants. If the lichen really was there in the ecosystem then the scientists could conclude that the system was free of a certain pollutant.
