YOU MUST KNOW THIS FOR YOUR TEST/FRQ!

What are the ingredients for photochemical smog?

(Select 4 correct answers)

Heat
Rain
Sunlight
VOCs
Nitrogen oxides (NOx)
What is happening to the “good” ozone layer?
Gradually being destroyed by man-made chemcals
Rapidly being healed by man-made chemcals
Gradually being healed by natural chemcals
Rapidly being destroyed by natural chemicals
How much damage can 1 Chlorine atom do?
Can heal 100,000 "good" ozone molecules
Can destroy 1,000 "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 lung cancer, also increasing 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
Causes increased amounts of UV radiation to reach Earth causing more skin cancer, also reducing 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
What causes “bad” ozone?
Released directly into the air by natural sources such as trees and volcanoes
Released directly into the air by vehicles and factories
Created by a chemical reaction between NOx and VOCs as well as sunlight
What are some sources of “bad” ozone?

(Select 4 correct answers)

Motor vehicle exhaust
Industrial facilities
Gasoline vapors
Electric vehicles
Electric utilities
How does “bad” ozone affect human health and environment?
Being exposed to "bad" ozone can cause skin cancer as well as rapid death to plants and animals that touch it
Humans are uneffected by "bad" ozone, but plants and other animals that are exposed develop black spots on their surfaces
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)

Continue to do everything the way you are currently doing it
Use approved refrigerants in air conditioning and refrigeration equipment
Check the air quality forecast in your area
Help your local electric utilities reduce ozone air pollution by conserving energy at home and the office
Reduce air pollution from cars, trucks, gas-powered lawn and garden equipment, boats and other engines by keeping equipment properly tuned and maintained
Protect yourself against sunburn.
Use household and garden chemicals wisely
