Please answer the following questions:
1. What are the criteria pollutants and what do they all have in common?
2. Explain how a secondary pollutant is formed and provide an example.
3. What specific incidents initiated the creation of the EPA in the United States? (Don't forget Dr.
Rachel Carlson!)
4. What specific tool is used to way the cost of benefit versus cleanup in the environment?
5. Name three ways you can decrease the amount of pollution you contribute to the
environment

1)The criteria pollutants are carbon monoxide, lead, nitrogen dioxide, ozone, particulate matter, and sulfur dioxide. Criteria pollutants are the only air pollutants with national air quality standards that define allowable concentrations of these substances in ambient air.

2)Examples of a secondary pollutant include ozone, which is formed when hydrocarbons (HC) and nitrogen oxides (NOx) combine in the presence of sunlight; NO2, which is formed as NO combines with oxygen in the air; and acid rain, which is formed when sulfur dioxide or nitrogen oxides react with water.

3)By bringing national attention to water pollution issues, the Cuyahoga River fire was one of the events that led to the creation of the federal Environmental Protection Agency and the Ohio Environmental Protection Agency.

4)sry idk this one ☝️

5)On Days when High Particle Levels are Expected, Take these Extra Steps to Reduce Pollution:

Reduce the number of trips you take in your car.

Reduce or eliminate fireplace and wood stove use.

Avoid burning leaves, trash, and other materials.

Avoid using gas-powered lawn and garden equipment.
