Pollutants for 200 An aerosol in any air system composed of solid particles or liquid droplets suspended in a gaseous medium. Pollutants for 300 Exists in the atmosphere from natural sources such as plants, wetlands and rice paddies. Exists in the atmosphere from synthetic sources such as benzene, toluene, formaldehyde, vinyl chloride, chloroform, etc., from unburned or partially formed hydrocarbons. Pollutants for 100 Colorless corrosive gas, whose source is natural and anthropogenic. Volcanoes / Coal and oil Pollutants for 200 _______ are the most dangerous form of Air Pollution, which are classified as carcinogens, neurotoxins, mutagens… Monitored by US EPA. (plastics mfg) Pollutants for 300 • Product of secondary atmospheric reactions. • NO2 is split and extra O reacts with another molecule of O2 to make ozone (O3). • Found in troposphere. Environ Air Laws for 100 1. Why did former President George Bush rescind the US agreement from participating in the Kyoto Protocol? Environ Laws for 200 • Which law was the first national legislation in the US aimed at air pollution control. • It provided federal grants to states to combat air pollution. Environ Law for 300 Which law was re-written to include the criteria pollutants and established primary and secondary standards for ambient air quality? Atmosphere for 100 Which layer of the atmosphere does you find: pollutants weather/climate mountains Atmosphere for 200 Name two differences that exist between the troposphere and the stratosphere. Atmosphere for 300 Two Questions: 1. ________ in the stratosphere prevents ultraviolet light from entering Earth’s atmosphere. 2. _______ in the troposphere can cause asthma, bronchitis, and other respiratory problems.

Illness for 200 In Industrialized countries, one of the biggest threats from air pollution is from soot or fine particulates. 1. What size particulates? 2. Name 3 types of health risks which are linked with air pollution. Illness for 400 Persistent inflammation of bronchi and small airways in the lungs that cause mucus buildup, a painful cough and involuntary muscle spasms. Illness for 600 Condition where airways become permanently constricted and alveoli are damaged Or destroyed. Diseased alveoli Phenomena for 200 Occurs when a stable layer of warmer air overlays cooler air, reversing the normal temperature decline w/increasing height and preventing convection currents from dispersing pollutants. What is this called? Phenomena for 400 Name the chlorine-based aerosols which are the principal agents of ozone depletion in the stratospheric layer. 1. Name this pollutant? 2. What were they used in/for? 3. Why is this depletion an issue? Phenomena for 600 A natural source of carbon dioxide in the atmosphere include: A. forest fires B. Volcanoes C. plant and animal decay releasing CO2 D. deforestation E. All of the above Legislation for 200 The discovery of the stratospheric ozone depletion prompted this international agreement to phase out most uses of CFC’s by the year 2000. This is called the_________, one of the most effective international agreements ever. Legislation for 400 “Dilution is the solution to pollution” was one of the early approaches to air pollution control. Give an example and explain its rationale. Legislation for 600 One of the most contested aspects of the Clean Air Act is the “new source review”, established in 1977. Explain what this is, the benefits and the disadvantages of this condition. Case Studies for 200 Mexico City is growing at an explosive rate…of 131,000 industries and 2.5 million vehicles spew out more than 5500 tons of air pollution daily. Which air pollutant is the culprit and explain its effects on the children in Mexico City. Case Studies for 400 Seven of the worst cities with high air pollution is in China. They emit 10 million tons of soot and 15 million tons of sulfur dioxide annually. How has this effected their populations-name 2 ways. Case Studies for 600 Norlisk, Russia (formerly a slave labor camp in 1935) is the most polluted in the world. Snow turns black as soon as it falls—state the type of pollution present in this Russian town. There is hope…cities are making progress in cleaning up our air pollution. One prime example is Cubatao, Brazil and was once called the “valley of death”. How did they clean up this city?
