8.3.1 Urban air pollution is caused by inputs from human activities to atmospheric systems, including nitrogen oxides (NOx), sulfur dioxide, carbon monoxide and particulate matter.
Draw a systems diagram to represent the syllabus point above.
8.3.2 Sources of primary pollutants are both natural and anthropogenic.
Primary pollutants are directly active at the point of emission. Include forest fires, dust and volcanic eruptions as natural sources. Include burning for agricultural and forest clearance, burning of fossil fuels and biomass for energy production, and dust from construction/roads as anthropogenic sources.
8.3.3 Most common air pollutants in the urban environment are either derived directly or indirectly from combustion of fossil fuels.
Using the same template doc as above, identify the common pollutants.
8.3.4 A range of different management and intervention strategies can be used to reduce urban air pollution.
Include strategies such as, but not limited to, improved public transportation, infrastructure for cycling, growing trees, natural screens, green walls, compulsory catalytic converters, limited car use and pedestrianized town centres.
How do the perspectives of these people differ? What might explain these differences?
Ove the next few weeks, photograph and share any examples you spot of managing urban air pollution in the ESS group chat.

Discuss in pairs and then write an individual response:
To what extent does acid rain impact upon the sustainability of environmental systems? [7]
