Photo smog

The primary pollutants that come from the complete combustion of fossil fuels include

• sulphur dioxide,

• nitrogen oxides

• carbon dioxide, water vapour

• carbon monoxide, hydrocarbons

• particulates

When the primary pollutants (PP) react in the atmosphere, they produce secondary pollutants such as

• Acid rain when the PP’s react with sunlight
• Tropospheric ozone when the PP’s react with water

True or false

Air pollution from the combustion of fossil fuels has negative impacts. Which of the following is not one of the impacts

• Particulates: makes the skin and fur dirty

• Carbon dioxide and water vapour: contribute to global climate change

• Sulphur dioxide: causes inflammation of the lungs, irritates the eyes increases the risk of cardiac disease.

• Nitrogen oxides (NOx): causes inflammation of the lungs

Which of the following in not true of the formation of photochemical smog?

• The main sources of volatile organic compounds (VOCs) industry, vehicles and solvents (e.g. used in paints and adhesives).

• The main sources of NOx are emissions from industry, power stations and vehicles.

• Forest fires reduce the levels of VOCs and particulate matter

• It occurs when sunlight activates reactions between nitrogen oxides (NOx) and volatile organic compounds (VOCs)

• The reactions result in the formation of ground level ozone and peroxyacyl nitrates (PAN).

Photochemical smog is mostly likely to be formed under which of the following conditions

• High levels of sunlight

• High emissions due to combustion of fossil fuels

• Calm or light winds

• Dry weather

• Correct topography

Which of the following does not apply to ground level ozone.

• Disrupts photosynthesis

  
  

• Is a stable gas

• Lung inflammation, coughing, wheezing, asthma.

• Irritates the eyes and nose

The second level of strategies in the pollution management model is – legislation and that includes international agreements, emission standards, building regulations and planning regulations. True or false

The final stage of pollution management is remediation.

A promotional saying for this final strategy could be

Afforestation = restoration

True or false
