SJSU Spring Semester 2020 Module 5 Local amp Indoor Air Pollution Frank R Freedman Course Instructor Overview Indoor Air Pollution Sources Indoor Air Pollution Prevention and Control Lecture 12 Outline. 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.. Indoor Air Quality. Indoor Air Pollution. Indoor air contains higher concentrations of pollutants than outdoor air (up to 70x). Indoor air pollution usually is a greater threat to human health than outdoor air pollution.. Casey . GUillaume. MPH 500 Foundations of Public Health. Professor Madeline Angela Meyer. Overview. What are indoor air pollutants? . Air quality importance. Health risks. Behavioral factors. Social factors. 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. Indoor Air Pollution (Chapter 24). Sources of Indoor Air Pollution. Sources of indoor air pollution can come from both human activities and natural processes. Two of the most common household pollutants are dust mites and pollen. what is the nature of the atmosphere. We live at the bottom of a thin layer of gases surrounding the earth called the atmosphere, which is divided into smaller spherical layers. In the troposphere, the layer closest to earth, about 75-80% of the earths air mass is found here.. Air . P. ollution. Alyssa Weibe . 4/28/14. What is the nature of the atmosphere . The two innermost layers of the atmosphere are the troposphere, which supports life, and the stratosphere, which contains the protective ozone layer.. FUNDAMENTALS OF ATMOSPHERIC SCIENCE.

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.
