The term Wet scrubber describes a variety of devices that remove pollutants from a furnace flue gas or from other gas streams. Wet scrubbers remove dust particles by capturing them in liquid droplets. wildfires) or synthetic (man-made); they may be in the form of gas, liquid or solid. x. Mercury (source- combustion of fossil fuel & plants)-brain & kidney damage. Content Guidelines 2. Air flows in a spiral pattern, beginning at the top (wide end) of the cyclone and ending at the bottom (narrow) end before exiting the cyclone in a straight stream through the centre of the cyclone and out the top. Disclaimer 9. Industries often emit large amounts of nitrogen and sulphur gases into the Earths atmosphere. Ammonia contributes significantly to the nutritional needs of terrestrial organisms by serving as a precursor to foodstuffs and fertilizers. The ultimate result is a change Methane is also an asphyxiate and may displace oxygen in an enclosed space. Ozone Layer Depletion Both indoor and outdoor air pollution have caused approximately 3.3 million deaths worldwide. Radon gas from radioactive decay within the Earths crust. Other Effects of Industrial Air Pollution Other common effects often associated with air pollution caused due to industrial emissions include increasing risk of occupational diseases such as pneumoconiosis and asbestosis. Scrubbers can be designed to collect particulate matter and/or gaseous pollutants. 1, 3-butadiene is another dangerous compound which is often associated with industrial uses.

Using low sulphur coal in industries. Toxic metals such as lead, cadmium and copper. In contrast, aerosol refers to particles and the gas together. It is normally encountered as a gas with a characteristic pungent odor. Particles larger than the cut point will be removed with a greater efficiency and smaller particles with a lower efficiency. Acid rain, first discovered in Air pollution is a change in the physical, chemical and biological characteristic of air that causes adverse effects on humans and other organisms. viii. ii. Air pollution results in polluting the air we breathe our entire atmosphere and also leads to global warming. In contrast to wet scrubbers which apply energy directly to the flowing fluid medium, an ESP applies energy only to the particulate matter being collected and therefore is very efficient in its consumption of energy (in the form of electricity). Over 200 million items of e-waste are thrown away every year in the U.S.? At abnormally high concentrations brought about by human activities (largely the combustion of fossil fuel), it is a pollutant, and a constituent of smog. Silicon dioxide (source- Stone cutting, pottery, glass manufacturing and cement industries) Silicosis, a cancerous disease. Inlet gas characteristics and dust properties (if particles are present) are of primary importance. Eroding air quality was linked to 10,000 additional U.S. deaths over a two-year period. i. Particulate matter formed from gaseous primary pollutants and compounds in photochemical smog. v. Volcanic activity, which produce sulphur, chlorine, and ash particulates. Chlorofluorocarbons (CFCs) harmful to the ozone layer emitted from products currently banned from use. Some of them are discussed at length below. There are various factors causing air pollution, but what comes from industries and factories is often considered a prime factors in air pollution.According to a study conducted by the Environmental Protection Agency, or EPA, it has been found that industrial pollution accounts for approximately 50 percent of the pollution in the United States of America. Methane is an extremely efficient greenhouse gas which contributes to enhanced global warming. Day by day the fresh air of the environment is getting polluted because of the mixing of particulates, biological molecules, and other harmful materials. In addition, they may be natural or man-made. Air pollution is a change in the physical, chemical and biological characteristic of air that causes adverse effects on humans and other organisms. iii. Methane is not toxic; however, it is highly flammable and may form explosive mixtures with air. In addition to destructive health effects, air pollution has a negative impact on the agricultural system and weather conditions, it changes the climate, ruins the crops, and causes foliage injuries.Plants suffer from necrotic lesions, yellowing of leafs which lead to reduced growth and death. There are Various Harmful Effects of the air Pollutants: i. Although in wide use, ammonia is both caustic and hazardous. iii. You are Prerna/Puneet. Now industries are Controlled or prescribed burning is a technique sometimes used in forest management, farming, prairie restoration or greenhouse gas abatement. Plagiarism Prevention 4. Global warming is largely considered one of the most hazardous and serious complications associated with air pollution caused by industries and other stationary sources of air pollution. Controlled burning stimulates the germination of some desirable forest trees, thus renewing the forest. ix. There are numerous serious ecological implications and health risks associated with industrial air pollution. It is considered to be a health hazard. Human activities, such as the burning of fossil fuels in vehicles, power plants and various industrial processes also generate significant amounts of aerosols. This leads to felling of large number of trees, as these are needed for construction and manufacture of paper etc. Previous article in issue; Next article in issue; Keywords. Methane, emitted by the digestion of food by animals, for example cattle. You can follow any responses to this entry through the RSS 2.0 feed. Radon is a colourless, odourless, naturally occurring, radioactive noble gas that is formed from the decay of radium. The following items are commonly used as pollution control devices by industry or transportation devices. With the increase in industrial plants in the rural areas of developing countries, the effects of industrial air pollution on the technical efficiency of agricultural production have attracted considerable attention. Article shared by. Particulates deposited on leaves can form encrustations and plug the stomata and also reduce the availability of sunlight. The cyclone geometry, together with flow rate, defines the cut point of the cyclone. transportation and energy production. The emission of various gases such as carbon monoxide, or CO, often results in various respiratory disorders such as bronchitis, asthma, chronic obstructive pulmonary disease, or COPD, in individuals. Ground level ozone (O3) formed from NOx and VOCs. the researchers write. Radioactive pollutants produced by nuclear explosions, war explosives, and natural processes such as the radioactive decay of radon. This results in blurred vision, headache, unconsciousness and death due to asphyxiation (lack of oxygen). ii. iv. Write an article, in 100-120 words, on Air Pollution Sources of particulate matter can be manmade or natural. Essay on Air Pollution Earlier the air we breathe in use to be pure and fresh. Learn more here. vii. Air pollution is getting worse, and data show more people are dying. By . iii. Within the NMVOCs, the aromatic compounds benzene, toluene and xylene are suspected carcinogens and may lead to leukaemia through prolonged exposure. When these gases react with water vapors in the atmosphere, they often change into more aggressive gases, namely nitric acid and sulphuric acid respectively. You can leave a response, or trackback from your own site. The understanding of the effects of industrial air pollution on technical efficiency will help researchers in making a sound estimation of agricultural loss and provide helpful insights for policy-makers. The design of wet scrubbers or any air pollution control device depends on the industrial process conditions and the nature of the air pollutants involved. Copyright 2010 Eco Coalition. Minimise/modify activities which cause pollution e.g. Report a Violation, Pollution: Different types of Environmental Pollutants (343 Words), Pollution and Pollutants: Classification, Causes, Effects and Sources, The Acid Rain: Causes, Effects and Control Measures (1495 Words). During this industrialization era, air pollution cannot be neglected fully, In a conical system, as the rotating flow moves towards the narrow end of the cyclone the rotational radius of the stream is reduced, separating smaller and smaller particles. In a wet scrubber, the polluted gas stream is brought into contact with the scrubbing liquid, by spraying it with the liquid, by forcing it through a pool of liquid, or by some other contact method, so as to remove the pollutants. v. Waste deposition in landfills, which generate methane. Industrial pollution can also impact air quality, and it can enter the soil, causing widespread environmental problems. Copyright 10. Breathing air in highly populated and polluted metropolitan cities can reduce your life expectancy by 2 to 3 years? The ozone layer is a gaseous blanket that helps in supporting and sustaining life on Earth by protecting us from various hazardous radiations such as UV rays. It often results in the melting of glaciers and snowcapped mountains, resulting in an increase in the water levels of seas and rivers, eventually increasing the risk of floods. VOCs are an important outdoor air pollutant. ii. v. Chloro-fluoro carbons (CFCs) (source- Refrigerators, air conditioners, foam shaving cream, spray cans and cleaning solvents)- Destroy ozone layer which then permits harmful UV rays to enter the atmosphere. This article discusses how Japan is tackling pollution through renewable energy and pollution beating technology. Pollutants also erode waxy coating of the leaves called cuticle. An important example of a secondary pollutant is ground level ozone one of the many secondary pollutants that make up photochemical smog. Also, these gases are the cause of many respiratory and other diseases. Hydrocarbons Poly-nuclear Aromatic Compounds(PAC) and Poly-nuclear Aromatic Hydrocarbons(PAH) (source- Automobile exhaust and industries, leaking fuel tanks, leaching from toxic waste dumping sites and coal tar lining of some water supply pipes)- Carcinogenic (may cause leukaemia). Apart from this, global warming also often has numerous serious health risks on humans such as increase in diseases like Lyme, malaria, cholera, dengue and plague, among others.
