In air pollution control, the pollutants in the air are subjected to microbiotic oxidation. Wet scrubbers are used in a number of industries such as large power plants, asphalt plants, steel plants, fertilizer plants, and acid plants.
People who exercise outdoors are susceptible to the adverse effects of air pollution because it involves deeper and faster breathing.
Pollutant Health effects at very high levels Nitrogen Dioxide, Sulphur Dioxide, Ozone These gases irritate the airways of the lungs, increasing the symptoms of those suffering from lung diseases Particles Fine particles can be carried deep into the lungs where they can cause inflammation and a worsening of heart and lung diseases Carbon Monoxide This gas prevents the uptake of oxygen by the blood.
Ozone layer is the thin shield high up in the sky that stops ultra violet rays from reaching the earth. VOC emissions are produced during combustion and their rate of production is affected by time in combustion chamber, fuel and air mix, temperature, turbulence, pressure and design of chamber.
Input control involves preventing a problem before it occurs, or at least limiting the effects the process will produce.
Case Studies of Air Pollution: Carbon Dioxide Carbon dioxide emissions have increased significantly during 19th century because of the use of coal, oil and natural gas.
Also spraying insecticides, pesticides like DDT on plants pollutes the ground water system and oil spills in the oceans have caused irreparable damage to the water bodies. Excessive burning of fuel which is a necessity of our daily lives for cooking, driving and other industrial activities; releases a huge amount of chemical substances in the air everyday; these pollute the air.
Daily tonnes of pollutants, mostly from automobiles and industries, are befouling the atmosphere, which contains three times more sulphur dioxide than the tolerance limit. Also called a flare stack, this is a chimney that is erected on oil rigs or oil wells, as well as landfills, chemical plants, and refineries.
The smog is a combination of smoke and fog prevent in London. The gray metal can be easily molded, formed and worked. Particulate matter also causes discoloration of buildings and other structures. The European Union would save billion euros a year if deaths caused by air pollution were diminished.
It is considered to be one of the most serious environmental issues in the world. Carbon monoxide is a poisonous, odorless, colorless gas that is formed when burning fossil fuels such as coal, petroleum and natural gas.
Some efforts to control air pollution are discussed below: As doing so will help reduce the air pollution caused for its generation. The gas reduces the ability of hemoglobin to carry oxygen to body tissue.
Buy and use only products or goods that are marked recyclable, as they can be reused and help in reducing pollution. It causes cancer, infertility, blindness, defects at the time of birth; can sterilise soil and affect air and water.
Water pollution not only harms the aquatic beings but it also contaminates the entire food chain by severely affecting humans dependent on these.
When acid rain infiltrates into soils, it changes the chemistry of the soil making it unfit for many living things that depend on the soil as a habitat or for nutrition. Five major input control methods may be adopted.
This can lead to a significant reduction in the supply of oxygen to the heart, particularly in people suffering from heart disease. We breathe in every polluted particle from the air; result is increase in asthma and cancer in the lungs.Air Pollution is the most prominent and dangerous form of pollution.
It occurs due to many reasons. Excessive burning of fuel which is a necessity of our daily lives for cooking, driving and other industrial activities; releases a huge amount of chemical substances in the air everyday; these pollute the air.
Short-term air pollution can aggravate the medical conditions of individuals with asthma and emphysema. Long-term health effects can include chronic respiratory disease, lung cancer, heart disease, and even damage to the brain, nerves, liver, or kidneys.
Air pollution, being one of the most serious global problems of the modern world, has many causes, among which it is possible to single out the industrial development, which affects dramatically the pollution of atmosphere in the result of emission of various gases and polluting substances from industrial areas, the burning of fuel by different means of transport, and the active use of.
10 powerful images that show the effects of pollution around the world now competes with China in terms of air pollution health burdens. shows the soot collected from the bonnet of his car.
Effects of air pollution A variety of air pollutants have known or suspected harmful effects on human health and the environment. In most areas of Europe, these pollutants are principally the products of combustion from space heating, power generation or from motor vehicle traffic.
What is air pollution and what are the various factors contributing to air pollution? and hot springs, the effect of this pollution is very small when compared to that caused by emissions from industrial sources, power and heat generation, waste disposal, and the operation of internal combustion engines.
The following figure shows Air.Download
