Nitrogen oxides (NOx)
Heat
What is happening to the “good” ozone layer?
Rapidly being destroyed by natural chemicals
Rapidly being healed by man-made chemcals
Gradually being healed by natural chemcals
Gradually being destroyed by man-made chemcals
How much damage can 1 Chlorine atom do?
Can destroy 1,000 "good" ozone molecules
Can heal 100,000 "good" ozone molecules
Can destroy 100,000 "good "ozone molecules
Can heal 1,000,000 "good" ozone molecules
How does depletion of “good” ozone affect human health and the environment?
Causes increased amounts of UV radiation to reach Earth causing more skin cancer, also reducing crop yields and plant growth
Causes increased amounts of UV radiation to reach Earth causing more lung cancer, also increasing crop yields and plant growth
Causes decreased amounts of UV radiation to reach Earth causing more lung cancer, also reducing crop yields and plant growth
Causes decreased amounts of UV radiation to reach Earth causing more skin cancer, also increasing crop yields and plant growth
What causes “bad” ozone?
Released directly into the air by vehicles and factories
Created by a chemical reaction between NOx and VOCs as well as sunlight
Released directly into the air by natural sources such as trees and volcanoes
What are some sources of “bad” ozone?
(Select 4 correct answers)
Industrial facilities
Electric utilities
Gasoline vapors
Electric vehicles
Motor vehicle exhaust
How does “bad” ozone affect human health and environment?
Humans are uneffected by "bad" ozone, but plants and other animals that are exposed develop black spots on their surfaces
Being exposed to "bad" ozone can cause skin cancer as well as rapid death to plants and animals that touch it
Breathing "bad" ozone can cause respiratory problems as well as damage to agricultural crops and ecosystems
What can we do/actions we can take to reduce our risks?
(Select 6 correct answers)
Reduce air pollution from cars, trucks, gas-powered lawn and garden equipment, boats and other engines by keeping equipment properly tuned and maintained
Help your local electric utilities reduce ozone air pollution by conserving energy at home and the office
Protect yourself against sunburn.
Check the air quality forecast in your area
Continue to do everything the way you are currently doing it
Use household and garden chemicals wisely
Use approved refrigerants in air conditioning and refrigeration equipment
