Causes of Air Pollution

Match the following term with its definition or description. Fine Particles enter the air from fuel burned by vehicles Coarse Particles can come from cement plants, incinerators, or the road Smog urban air pollution composed of a mixture of smoke and fog produced from industrial pollutants and burning fuels Temperature Inversions the atmospheric condition in which warm air traps cooler air near Earth's surface. All of the following are causes of air pollution EXCEPT… acid rain vehicle emissions industrial waste What causes air pollution? According to the information in the box above, what environmental issue is China facing? pollution of the Yangtze River overfishing of the Yangtze River deforestation on the banks of the Yangtze River What is the difference between primary and secondary pollutants? Primary pollutants are put indirectly into the air whereas secondary pollutants are caused by chemical reactions involving air pollutants. Secondary pollutants are put directly into the air whereas primary pollutants are caused by chemical reactions involving air pollutants. Primary pollutants are the ones scientist focus on the most; secondary pollutants come second. Primary pollutants are put directly into the air whereas secondary pollutants are caused by chemical reactions involving air pollutants. Use the following graphs for the next 2 questions. Which area has the most deaths linked to air pollution? Western Pacific Southeast Asia Africa Americas Which disease had the most deaths linked to air pollution? COPD Acute Lower Respiratory Disease Lung Cancer Stroke Ischaemic Heart Attack A student was studying the changes in carbon dioxide levels over time, as shown in the readings at Mauna Loa atmospheric station in Hawaii. In trying to reduce levels of carbon dioxide, the student wants to design and implement solutions to accomplish this goal. Which of these solutions could potentially lower carbon dioxide and greenhouse gas emissions if implemented? Select all that apply. The student could walk to locations rather than use a car to reduce carbon dioxide emissions. The student could use biomass to heat the home rather than a furnace. The student could promote the use of hybrid vehicles rather than traditional fuel combustion engine vehicles. The student could promote the use of solar panels in her home and neighborhood for electricity generation. The student could increase meat consumption rather than vegetable and grain consumption to reduce carbon dioxide emissions. How much of our air pollution comes from motor vehicles? about 2 about 1 16% 90% Sort examples of primary and secondary pollutants and where they come from. Primary Pollutants soot from smoke Household products Power Plants VOCs Secondary Pollutants ground-level ozone forms from emissions from cars that react with the sun and oxygen in the air
