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
(a)
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
The diagram shows normal conditions and a thermal inversion. Which side shows the thermal inversion A or B
(a)
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
(a)
The final stage of pollution management is remediation.
A promotional saying for this final strategy could be
Afforestation = restoration
True or false
(a)
Which on of the following is NOT damage caused by photochemical smog
