Air pollution is one of the m… In addition, they may be natural or man-made. It is a product by incomplete combustion of fuel such as natural gas, coal or wood. Acid rain has various health and natural dangers. v. Volcanic activity, which produce sulphur, chlorine, and ash particulates. 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. Methane is also an asphyxiate and may displace oxygen in an enclosed space. vi. © 2020 Elsevier Inc. All rights reserved. Methane, emitted by the digestion of food by animals, for example cattle. Content Guidelines 2. Without considering the changes in the production function, the technical efficiency estimated using the traditional stochastic frontier analysis method appears to be overestimated compared with that estimated using a modified measure. v. Waste deposition in landfills, which generate methane. CO damages air passages in individuals, leading to respiratory disorders. It is responsible for photochemical smog, acid rain etc. v. Military, such as nuclear weapons, toxic gases, germ warfare and rocketry. 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. With the advent of industrialization and profuse use of fossil fuels, the quality of air that we breathe has deteriorated continuously. 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. Respiratory Disorders Day by day the fresh air of the environment is getting polluted because of the mixing of particulates, biological molecules, and other harmful materials. vii. Smokes, gases like carbon monoxide, greenhouse gases like carbon dioxide etc. Asbestos particles (source- Mining activities) – Asbestosis – a cancerous disease of the lungs. Particles larger than the cut point will be removed with a greater efficiency and smaller particles with a lower efficiency. iv. Disclaimer 9. These air pollutants can be either natural (e.g. Ammonia, either directly or indirectly, is also a building block for the synthesis of many pharmaceuticals. This leads to felling of large number of trees, as these are needed for construction and manufacture of paper etc. Image Guidelines 5. Wet scrubbers remove dust particles by capturing them in liquid droplets. Peroxyacetyl nitrate (PAN) causes silvering of lower surface of leaf, damage to young and more sensitive leaves and suppressed growth.

Our findings indicate that industrial air pollution lowers the marginal products of factors, alters the relationships of labour-capital and chemical-capital from complementarity to substitution, and changes the seed-chemical relationship from substitution to complementarity. 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. Since coal and petroleum often contain sulphur compounds, their combustion generates sulphur dioxide. Ozone (O3) is a key constituent of the troposphere (it is also an important constituent of certain regions of the stratosphere commonly known as the Ozone layer). iii. These activities also produce worse air pollution. Addition of harmful and unwanted substance to air is termed as air pollution. Some of them are discussed at length below. All Rights Reserved.

Rural areas are being converted to urban areas continuously and unplanned industrialization is taking place. x. Mercury (source- combustion of fossil fuel & plants)-brain & kidney damage. iii. However, if carbon monoxide is present in increased levels in the atmosphere, it can even cause the death of the person, by inhibiting oxygen intake by combining with hemoglobin. An electrostatic precipitator (ESP), or electrostatic air cleaner is a particulate collection device that removes particles from a flowing gas (such as air) using the force of an induced electrostatic charge. on Monday, April 19th, 2010 at 11:43 pm and is filed under Air Pollution, Know the Facts. Although in wide use, ammonia is both caustic and hazardous. By continuing you agree to the use of cookies. Electrostatic precipitators are highly efficient filtration devices that minimally impede the flow of gases through the device, and can easily remove fine particulate matter such as dust and smoke from the air stream. Air pollution refers to the contamination of atmospheric air due to the presence of some substances and gases (from anthropogenic or natural sources) which have harmful and poisonous effects. Global warming has various serious implications both on the ecological balance as well as human health. Such polluted air is causing health problems, diseases and death. Toxic metals – such as lead, cadmium and copper. The ultimate result is a change in the natural environment and/or ecosystem. It is a natural gas in the atmosphere. A high speed rotating (air) flow is established within a cylindrical or conical container called a cyclone. Vehicular exhaust is a major source of carbon monoxide. 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. 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. This entry was posted Pollutants can be in the form of solid particles, liquid droplets, or gases. TOS 7. Other common effects often associated with air pollution caused due to industrial emissions include increasing risk of occupational diseases such as pneumoconiosis and asbestosis. They can either destroy contaminants or remove them from an exhaust stream before it is emitted into the atmosphere. O3 causes flecks on leaf surface, premature aging, necrosis and bleaching. iii. Also, the resultant scrubbing liquid must be treated prior to any ultimate discharge or being reused in the plant: i. Vehicular pollution can be checked by regular tune-up of engines; replacement of more polluting old vehicles; installing catalytic converters; by engine modification to have fuel efficient (lean) mixtures to reduce CO and hydrocarbon emissions; and slow and cooler burning of fuels to reduce NOx emission. Other hydrocarbon VOCs are also significant greenhouse gases via their role in creating ozone and in prolonging the life of methane in the atmosphere, although the effect varies depending on local air quality. Acid rain, first discovered in … These greenhouse gases often result in an increase in the atmospheric temperature, causing global warming. Further oxidation of SO2, usually in the presence of a catalyst such as NO2, forms H2SO4, and thus acid rain. Plagiarism Prevention 4. Ozone Layer Depletion Some particulates occur naturally, originating from volcanoes, dust storms, forest and grassland fires, living vegetation, and sea spray. Major primary pollutants produced by human activity include: SO2 is produced by volcanoes and in various industrial processes. Privacy Policy 8. Particulates, alternatively referred to as particulate matter (PM) or fine particles, are tiny particles of solid or liquid suspended in a gas. Air pollution is getting worse, and data show more people are dying. 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. Pollutants also erode waxy coating of the leaves called cuticle. viii. You can follow any responses to this entry through the RSS 2.0 feed. ii.

Using survey data collected from southwestern China, this paper analyses the effects of point-source air pollution on rice production by incorporating air pollution as an input in a translog production function. x. Ammonia (NH3) – emitted from agricultural processes. Content Filtrations 6. 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. Air pollution at construction sites is higher than the standard. There are numerous serious ecological implications and health risks associated with industrial air pollution. ... the researchers write. 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. Silicon dioxide (source- Stone cutting, pottery, glass manufacturing and cement industries) – Silicosis, a cancerous disease. Averaged over the globe, anthropogenic aerosols—those made by human activities—currently account for about 10 per cent of the total amount of aerosols in our atmosphere. There are Various Harmful Effects of the air Pollutants: i. Fluorides cause necrosis of leaf-tip while ethylene results in epinasty, leaf abscission and dropping of flowers. This entry was posted on Monday, April 19th, 2010 at 11:43 pm and is filed under Air Pollution, Know the Facts. ix. Air pollution from industrial shutdowns and startups worse than thought February 14, 2018 6.38am EST Nikolaos Zirogiannis , Alex J. Hollingsworth , David Konisky , Indiana University Nitrogen Oxides (source- Automobile exhausts, burning of fossil fuels, forest fires, electric generation plants, smelting plants, industrial boilers, petroleum refineries and volcanic eruptions)- Forms photochemical smog, at higher concentrations causes leaf damage or affects the photosynthetic activities of plants and causes respiratory problems in mammals. This results in blurred vision, headache, unconsciousness and death due to asphyxiation (lack of oxygen). Persistent free radicals – connected to airborne fine particles could cause cardiopulmonary disease. i. Eroding air quality was linked to 10,000 additional U.S. deaths over a two-year period. By . Using low sulphur coal in industries. Photochemical and chemical reactions involving it drive many of the chemical processes that occur in the atmosphere by day and by night. 70% of toxic waste in U.S. landfills consists of e-waste, items such as hard drives, monitors, servers, etc? 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). Chlorofluorocarbons (CFCs) – harmful to the ozone layer emitted from products currently banned from use. Effects of industrial air pollution on the technical efficiency of agricultural production: Evidence from China. Furthermore, the complementary elasticities of labour-chemical and labour-seed are reduced, whereas that of capital-seed is improved. Read this article to learn about the types, sources, effects and control of air pollution! Air pollution is defined as the addition of various hazardous chemicals, particulate matter, toxic substances and biological organisms into the Earth’s atmosphere. Industrial pollution has caused significant harmful effects to the environment and is one of the biggest culprits of Global Warming. Copyright 10. You are Prerna/Puneet. It results in the erosion of monuments and buildings, makes the soil acidic in nature, resulting in reduction of plant and animal growth, among other issues. Ground level ozone (O3) formed from NOx and VOCs. An air pollutant is known as a substance in the air that can cause harm to humans and the environment. They, along with industrial development, are causing a lot of air pollution, not only in big cities but also in small towns. ii. Industrial pollution can also impact air quality, and it can enter the soil, causing widespread environmental problems. have also contributed to making our air poisonous. Air pollution is a change in the physical, chemical and biological characteristic of air that causes adverse effects on humans and other organisms.
