Silicon dioxide (source- Stone cutting, pottery, glass manufacturing and cement industries) – Silicosis, a cancerous disease. 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). Sources of particulate matter can be manmade or natural. Air pollution is getting worse, and data show more people are dying. Effect of air pollution on the technical efficiency of rice production was analysed; Air pollution lowers the marginal products of production factors; Air pollution alters the complementary or substitutional relationships among factors; Air pollution changes the complementary elasticities of some factors; A new measure considering pollution was used to estimate the technical efficiency. Air pollution is one of the m… Using low sulphur coal in industries. An important example of a secondary pollutant is ground level ozone — one of the many secondary pollutants that make up photochemical smog. Content Filtrations 6. 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. Fire is a natural part of both forest and grassland ecology and controlled fire can be a tool for foresters. Since coal and petroleum often contain sulphur compounds, their combustion generates sulphur dioxide. Air pollutants during day time affect plants by entering the leaf through these stomata more than night. Disclaimer 9. During the day time the stomata are wide open to facilitate photosynthesis.

Agricultural air pollution comes mainly in the form of ammonia, which enters the air as a gas from heavily fertilized fields and livestock waste. 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. xii. Particulates, alternatively referred to as particulate matter (PM) or fine particles, are tiny particles of solid or liquid suspended in a gas. 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. Acid rain, first discovered in … transportation and energy production. This leads to felling of large number of trees, as these are needed for construction and manufacture of paper etc. Further oxidation of SO2, usually in the presence of a catalyst such as NO2, forms H2SO4, and thus acid rain. Wet scrubbers remove dust particles by capturing them in liquid droplets. Apart from these, acid rain causes serious health disorders such as cancer, skin disorders and even death. Day by day the fresh air of the environment is getting polluted because of the mixing of particulates, biological molecules, and other harmful materials. Asbestos particles (source- Mining activities) – Asbestosis – a cancerous disease of the lungs. Toxic metals – such as lead, cadmium and copper. Radon is a colourless, odourless, naturally occurring, radioactive noble gas that is formed from the decay of radium. Controlled or prescribed burning is a technique sometimes used in forest management, farming, prairie restoration or greenhouse gas abatement. Some of them are discussed at length below. Pollutants also erode waxy coating of the leaves called cuticle. The number of cars, motorbikes and other vehicles has been increasing day-by-day. It is responsible for photochemical smog, acid rain etc. By continuing you agree to the use of cookies. 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. The ultimate result is a change in the natural environment and/or ecosystem. N02 results in increased abscission and suppressed growth. vii. Increased levels of fine particles in the air are linked to health hazards such as heart disease, altered lung function and lung cancer. Air pollution is a change in the physical, chemical and biological characteristic of air that causes adverse effects on humans and other organisms. These activities also produce worse air pollution. i. Particulate matter formed from gaseous primary pollutants and compounds in photochemical smog. Rather, they form in the air when primary pollutants react or interact. Methane is also an asphyxiate and may displace oxygen in an enclosed space. Peroxyacetyl nitrate (PAN) – similarly formed from NOx and VOCs. iv. Inlet gas characteristics and dust properties (if particles are present) are of primary importance. Methane is not toxic; however, it is highly flammable and may form explosive mixtures with air. Furthermore, the complementary elasticities of labour-chemical and labour-seed are reduced, whereas that of capital-seed is improved. wildfires) or synthetic (man-made); they may be in the form of gas, liquid or solid. Particles larger than the cut point will be removed with a greater efficiency and smaller particles with a lower efficiency. Addition of harmful and unwanted substance to air is termed as air pollution. This results in blurred vision, headache, unconsciousness and death due to asphyxiation (lack of oxygen). 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. Secondary pollutants are not emitted directly. iii. You can leave a response, or trackback from your own site. 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. 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). Essay on Air Pollution – Earlier the air we breathe in use to be pure and fresh. Mechanical collectors (dust cyclones, multi-cyclones)- Cyclonic separation is a method of removing particulates from an air, gas or water stream, without the use of filters, through vortex separation. Now industries are … 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. Industrial air pollution. Radioactive pollutants – produced by nuclear explosions, war explosives, and natural processes such as the radioactive decay of radon. But, due to increasing industrialization and concentration of poisonous gases in the environment the air is getting more and more toxic day by day. Air pollution is defined as the addition of various hazardous chemicals, particulate matter, toxic substances and biological organisms into the Earth’s atmosphere. Click here to get an answer to your question ️ write an article on 'industrialization and air pollution' plss answer this fastly Some particulates occur naturally, originating from volcanoes, dust storms, forest and grassland fires, living vegetation, and sea spray. The damage can result in death of the plant.S02 causes bleaching of leaves, chlorosis, injury and necrosis of leaves. Industrial pollution has caused significant harmful effects to the environment and is one of the biggest culprits of Global Warming. Damage to leaf structure causes necrosis (dead areas of leaf), chlorosis (loss or reduction of chlorophyll causing yellowing of leaf) or epinasty (downward curling of leaf), and abscission (dropping of leaves). have also contributed to making our air poisonous. 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. Odours – such as from garbage, sewage, and industrial processes. 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. The ozone layer protects the earth from the ultraviolet rays sent down by the sun. Article shared by. iv. iii. It is considered to be a health hazard. Japan began to look into its pollution problem back in the 1970s when particulate matter levels in the air reached dangerous levels. Industrial pollution has caused significant harmful effects to the environment and is one of the biggest culprits of Global Warming. Air pollution has increased by urbanization and industrialization.

Respiratory Disorders 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. v. Volcanic activity, which produce sulphur, chlorine, and ash particulates. Chlorofluorocarbons (CFCs) – harmful to the ozone layer emitted from products currently banned from use. Asphyxia or suffocation may result if the oxygen concentration is reduced to below 19.5% by displacement. Especially nitrogen dioxide are emitted from high temperature combustion. Particulates deposited on leaves can form encrustations and plug the stomata and also reduce the availability of sunlight. This is one of the causes for concern over the environmental impact of the use of these fuels as power sources. Any droplets that are in the scrubber inlet gas must be separated from the outlet gas stream by means of another device referred to as a mist eliminator or entrainment separator (these terms are interchangeable). A greenhouse gas emitted from combustion but is also a gas vital to living organisms. “Mobile Sources” include motor vehicles, marine vessels, aircraft and the effect of sound etc. Global warming has various serious implications both on the ecological balance as well as human health. These air pollutants can be either natural (e.g. 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. Content Guidelines 2. Acid rain has various health and natural dangers. Scrubbers can be designed to collect particulate matter and/or gaseous pollutants. Plagiarism Prevention 4. iii. By . During this industrialization era, air pollution cannot be neglected fully, … Classic smog results from large amounts of coal burning in an area caused by a mixture of smoke and sulphur dioxide.
