PPT-AIR POLLUTION Air pollutants

gases amp particulate material added to the atmosphere Can affect climate or harm people Air pollution the release of pollutants Outdoor ambient air pollution pollution outside Has recently decreased due to government policy and improved technologies in developed countries. L. U T I O N. Identifying and Understanding Air, Water, and Soil Pollution. Air Pollution. Atmosphere need to know:. Air is more dense at sea level. 75-80% of air mass found in troposphere. Atmosphere contains 78% N, 21%O, and 1% trace gases like, methane, nitrous oxide, ozone, argon, water vapor, and carbon dioxide. Also soot, and dust..

LT 7C: Describe the major outdoor and indoor air pollution problems, discuss the causes and effects of these problems and explain possible solutions to them..  . Outdoor Air Pollution. The presence of chemicals in the atmosphere in concentrations high enough to harm organisms, ecosystems, or human-made materials, or to alter the climate. Chapter 8. POLLUTION AND POLLUTANTS. Pollution – the presence of harmful substances in the environment.. Pollutant – any substance that causes pollution.. Air pollutant – any material that gets into the air and degrades its quality (may be gases or small particles).. Stretch across much of India, Bangladesh, China, and the western Pacific Ocean. Air pollution connects the world. Pollutants can circle the globe in about two weeks. Stricter air pollution standards and continued shifts towards cleaner fuels are needed. 2. ). 20.95% Oxygen (O. 2. ). 0-4% Water Vapor (H. 2.
