The Simpson's diversity index (SDI) is used to determine the impact of motor vehicle exhaust on plants along a gradient/transect as you move away from the highway.

• This is a direct measurement of non-point source pollutant

• This is a indirect measurement of point source pollutant

• This is a direct measurement of point source pollutant

• This is an indirect measurement of non-point source pollutant

Which of the following is NOT an impact of air pollution?

• Deterioration of buildings

• Soil erosion

• Respiratory health problems

• Acid rain

CFCs cause....?

• Tropospheric ozone

• Ozone hole in the stratosphere

• Acid deposition

• Eutrophication

Which of the following is most likely a potential non-point source of pollution?

• A pipe releasing effluent from a factory into a lake

• A nuclear power station released hot water into the ocean

• Fertilizer spread over several fields is leaching excess nitrates into the groundwater

• Runoff from pile of manure is running into a river

An example of particulate air pollution is

• Radon

• Tropospheric ozone

• Carbon monoxide from vehicle emissions

• Smoke from burning wood

• secondary biodegradable pollutants

• primary biodegradable pollutants

• secondary non-biodegradable pollutants

Lichen grow on trees are an indicator species of air quality in a forest near an airport.

• This is a indirect measurement of point source pollutant

• This is a direct measurement of non-point source pollutant

• This is a indirect measurement of non-point source pollutant

• This is a direct measurement of point source pollutant

Which of the following is most likely a potential point source of pollution?

• Increased soil erosion due to extensive logging in the Amazon rainforest.

• High levels of tropospheric ozone are measured at a busy intersection on a sunny day.

• A volcanic eruption releases so much dust into the earth's atmosphere to cool global temperature by 2 degrees.

• Coniferous trees on the side of a highway are dying from increased acid depostion due to traffic emissions.

The secondary pollutant in this list is

• sulfur dioxide from burning coal

• Hot water released from a factory

• Acid deposition

• Nitrogen dioxide from vehicle emissions
