To what extent is pollution impacting human food production systems?

Outline, using examples, the differences between primary and secondary pollution.

Outline the conditions and processes that lead to the formation of photochemical smog.

Evaluate one management strategy for urban air pollution.

Describe the formation of tropospheric ozone.

Human activities affect the concentration of both stratospheric and tropospheric ozone.

Outline the differences in these two effects by completing the following table.

Suggest possible reasons for the overall trends of tropospheric ozone levels in Figure 3.

Outline why a high concentration of ozone in the troposphere is a direct problem for humans, while in the stratosphere it is a benefit to humans.

State two factors necessary for the chemical formation of ozone in the troposphere.

With reference to Figure 3, calculate the difference between the highest concentration and lowest concentration of tropospheric ozone.

Urban air pollution can become a problem as human populations develop. Evaluate urban air pollution management strategies at the three levels of intervention.

Explain why the formation of photochemical smog may have harmful effects on the environment of cities such as Santiago (Chile).

Identify one human factor that contributes to photochemical smog.

With reference to named examples, distinguish between a primary and secondary pollutant.

Disturbance of the composition and processes of the atmospheric system through human activity always disturbs the equilibria of marine systems.

Discuss the validity of this statement with reference to named examples.

Explain how changes in the concentration of stratospheric and tropospheric ozone in the atmosphere can affect global biodiversity.
