Chapters 5,10,18,19,20 Test Study Guide FRQ -Air Pollution= Is the presence of chemicals in the troposphere in high concentrations high enough to harm organisms, ecosystems, or materials, and high enough to alter climate. -Outdoor Pollutants= mostly human inputs, occur in industrialized and urban areas where people, cars, and factories are concentrated. (burning fossil fuels in power plants, factories, and cars) -Two Types of Outdoor Pollution -Primary Pollutants= Harmful substances that are emitted directly into the air. (most hydrocarbons and suspended particles) -Secondary Pollutants= Some primary pollutants reacting with one another or with the basic components of air to form new harmful pollutants. (Most NO3- AND SO42- Salts)

HI ALEX YOURE MY FAVORITE IN THIS WHOLE ENTIRE WORLD!! (and I like him so much oh my gosh) Chapter 15 Notes Trini Soza Air pollution The introduction of chemicals, particulate matter, or microorganisms into the atmosphere at concentrations high enough to harm plants, animals, and materials such as buildings, or to alter ecosystems - Air pollution is the most widespread environmental damage. - 147 million metric tons of air pollution released each year by the US. - The world releases about 2 billion metric tons a year. - Air quality has improved over the past 20 years in developed countries. - Developing countries however have higher air pollution sometimes ten times higher than the pollution levels considered safe for human health. Natural Air pollution:

Name: ________tyler antebi___________________________ Pg.___1 Mrs. Strype - 8 Acid Rain Internet Activity Sulfur dioxide and nitrogen oxides from the burning of fossil fuels react with water and oxygen to form acids. Rainwater is naturally slightly acidic, but this additional acid makes it even more so. Acid rain harms wildlife and upsets the balance of an ecosystem. In this activity, you'll learn what acid rain is and how you can help reduce it. Go to the website What is Acid Rain? What's the definition of acid rain? Acid rain is referring to a mixture of wet and dry materials from the atmosphere containing high amounts acid. Compare wet and dry deposition. Wet Acidic rain, Snow, Fog Acids fall in types of wet or moist weather. Dry Dust, Smoke

Outdoor Air Pollutants What are the major classes of outdoor pollutants? Natural sources--- 1. dust and other suspended particles 2. Sulfur oxides from volcanoes 3. Carbon oxides and particulates from fires 4. Pollen 5. Methane and hydrogen sulfide from decay 6. Salt from oceans * Most spread out and are rarely harmful http://www.epa.gov/air/urbanair/ Other sources--- 1. Volatile organic compounds (VOCs) methane, propane, CFC 2. Suspended particulate matter (SPM) solids dust, lead, pesticides 3. Radioactive substances- radon, iodine 4. Hazardous air pollutants (HAPs) can cause birth defects, cancer
