PPT-EMISSION OF POLLUTANTS

There has been rapid worldwide advancements in science and technology But all these advancements have contributed to various forms of pollution Sources 1 Industries Industrial pollutants have been one of the major sources of pollution and affects resources like . Introduction II Main air pollutants and their effects on human health and the environment III IV Policy approach to emissions at national and regional level Who are we?. What do we do?. What is air pollution?. Discussion in groups. Pollution. The process of making the air, water or soil dirty. . Pollutants. A substance that makes the air, water or soil dirty.. Pollution Control to save. the Earth. Environmental Pollution: . Definition – Causes, pollution effects and control measures of Air, Water, Soil, Marine, Noise, Thermal, Nuclear hazards. Solid waste management: causes, effects and control measures of urban and industrial wastes, pollution measures, case studies, Disaster management: floods, earthquake, cyclone and landslides.. 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. 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. Marti Blad, Ph.D., P.E. .. Yavapai Apache Nation. 2. What is the Difference?. 3. What we will learn. Pollutants move and spread in air. Up and down (vertical). Away and outward (horizontal). Dispersion vs Diffusion. = gases & 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. 2. ). 20.95% Oxygen (O. 2. ). 0-4% Water Vapor (H. 2.
