5.9.3.2 Properties and effects of atmospheric pollutants

Question 1

What are the major problems caused by water?

Answer 1

None.

Question 2

What are the major problems caused by carbon dioxide

Answer 2

Global warming and climate change

Question 3

What are the properties and problems caused by carbon monoxide?

Answer 3

It is a toxic gas- colourless and odourless which therefore is hard to detect.
Can cause low blood oxygen (blood poisoning)

Question 4

What are the main problems caused by sulphur dioxides/oxides (impurities in fuels)

Answer 4

Acid rain and respiratory issues.

Question 5

What are the main problems caused by nitrogen oxides (N2 + O2 in air reacting in hot engines)

Answer 5

Smog created- respiratory issues (asthma) and acid rain.

Question 6

What are the main problems caused by particulates (soot-carbon impurities/ unburnt hydrocarbons)

Answer 6

Global dimming, health/respiratory problems e.g asthma.

Question 7

What is a solution to trap particulates, such as carbon

Answer 7

Install filters in diesel engines.

Question 8

What are solutions to balancing and cancelling out carbon Dioxide levels in the atmosphere

Answer 8

Taxing emissions as well as forcing/ encouraging companies to plant trees (for every one which is cut down a new one is planted)

Question 9

What is the solution to reducing amounts of fossil fuels being used

Answer 9

Using renewable resources such a solar, wind, HEP, bio energy and tidal energy. ‘Carbon neutral
(generating electricity)
As well as decreasing emissions

Question 10

What are the solutions to carbon dioxide levels in the atmosphere

Answer 10

Carbon capture + storage methods- removes/captures CO2 in the atmosphere converting into something less harmful

Question 11

What is the solution to reducing sulphur oxide levels

Answer 11

Reducing emissions
