Atmospheric pollution - tropospheric ozone and carbon monoxide

Question 1

What are the sources of tropospheric ozone

Answer 1

• photochemical reaction of NOX’s and oxygen.
• The oxygen break off and react with other O2 molecules to form O3

Question 2

What are the effects of tropospheric ozone

Answer 2

• photochemical smog
• respiratory issues
• reduces growth for plants and trees

Question 3

What are some controls of tropospheric ozone

Answer 3

• control NOX’s
• public awareness
• increase public transport

Question 4

What are the sources for carbon monoxide

Answer 4

• incomplete combustion of fossil fuels

Question 5

What are the effects of carbon monoxide

Answer 5

• CO binds to hemoglobin which prevents it from carrying O2 from the lungs to the tissues

Question 6

What are some controls of carbon monoxide

Answer 6

• catalytic converter
• ventilation in homes
• public awareness

Question 7

What is a biotic index

Answer 7

• a metric used to assess the quality of an environment by measuring the types and amounts of organisms that live in it

Question 8

Name some biotic indices and what they tell us about pollutants

Answer 8

• lichen - qual of air
• salmon - food source, climate change
• bats - disease, environmental health

Question 9

What are lichen

Answer 9

• made up of 2 or more organisms
• symbiotic relationship = between fungus and algae
• fungus requires carbohydrates
• algae require shelter

Question 10

What makes a good indicator species

Answer 10

• easy to identify
• abundant in normal conditions
• easy to find

Question 11

What are the advantages of using biotic indices

Answer 11

• cheap
• low level of technology needed
• can bioaccumulate

Question 12

What are the disadvantages of using biotic indices

Answer 12

• difficulty with identification of species
• can be time consuming
