Answer:
Air quality programmes have brought us benefits in many areas. For example, burning low-sulphur coal and oil in factories and power plants has lowered pollution in many cities. In order to meet standards, automobile engines are redesigned and new cars have been equipped with devices like catalytic converter which changes pollutants into harmless substances and reduces air pollution.
Question 25.
Why do we still need to find out better ways to control air pollution?
(ତଥାପି ଆମେ କାହିଁକି ବାୟୁ ପ୍ରଦୂଷଣ ନିୟନ୍ତ୍ରଣ ନିମନ୍ତେ ଉନ୍ନତ ଉପାୟମାନ ବାହାର କରିବା ଦରକାର କରୁଛୁ ?)
Answer:
Although the formulation of certain laws and set of standards and norms have checked air pollution up to some extent, it hasn’t been completely checked. So we still need to find out better ways to control air pollution. It is not easy to bring about the new development needed to control it. Now physicians, engineers, botanists and meteorologists are carrying out research, seeking new ways to check it. In the future, we can breathe pure air in the cities where the sunlight is no longer blocked by an umbrella of air pollution.
E. Let’S Go Beyond The Text
Question 1.
Why does the oxygen level in the atmosphere get reduced? What could be its consequences?
(ବାୟୁମଣ୍ଡଳରେ ଅମ୍ଳଜାନ ସ୍ତର କମିଯାଇଛି କାହିଁକି ? ଏହାର ପରିଣାମ କ’ଣ ହୋଇପାରେ ? )
Answer:
The oxygen level in the atmosphere gets reduced for many reasons. Due to deforestation, the photosynthesis process has been reduced and the amount of oxygen gets reduced. Besides burning process also reduces the amount of oxygen in the atmosphere. If it so happens then living beings will be definitely deprived of availing adequate oxygen. Besides, through respiration oxygen gets converted into carbon dioxide which traps radiation that reaches the earth from the sun, as a result, the atmosphere becomes warmer and would eventually lead to global warming.
Question 2.
How do the chemical industries cause dangerous air pollution? What are its far-reaching consequences?
(ରସାୟନ ଶିଳ୍ପଗୁଡ଼ିକ କିପରି ବିପଜନକ ବାୟୁ ପ୍ରଦୂଷଣ ସୃଷ୍ଟି କରୁଛନ୍ତି ? ଏହାର ସୁଦୂରପ୍ରସାରୀ ପରିଣାମ କ’ଣ ?)
Answer:
The chemical industries release certain toxic fumes into the atmosphere, along with smoke. It mingles with the atmospheric air and pollutes it. When people inhale that toxic substance, they suffer from serious diseases.
Question 3.
How is acid rain caused?
(ଅମ୍ଳବୃଷ୍ଟି କିପରି ସୃଷ୍ଟି ହୁଏ ?)
Answer:
Acid rain is a broad term referring to a mixture of wet and dry deposition from the atmosphere containing higher than normal amounts of nitric and sulphuric acid. The chemical forerunners of acid rain formation result from both natural sources such as volcanoes and decaying vegetation and man-made sources primarily emissions of sulphur dioxide and nitrogen oxides resulting from fossil fuel combustion. Acid rain occurs when these gases react in the atmosphere with water, oxygen and other chemicals to form various acidic compounds.
Question 4.
How does polluted air travel from one country to another?
(ପ୍ରଦୂଷିତ ବାୟୁ କିପରି ଗୋଟିଏ ଦେଶରୁ ଅନ୍ୟ ଦେଶକୁ ଯାଇଥାଏ ?)
Answer:
The polluted air is carried away by the wind from one country to another, often for distances of thousands of miles.
Question 5.
What steps can be taken to reduce the pollution caused by automobiles? Is air pollution a global problem?
(ମୋଟରଗାଡ଼ିଦ୍ଵାରା ସୃଷ୍ଟି ହେଉଥିବା ପ୍ରଦୂଷଣକୁ କମାଇବାପାଇଁ କି କି ପଦକ୍ଷେପ ନିଆଯାଇପାରେ ? ଏହା ଏକ ଜାଗତିକ ସମସ୍ୟା କି ?)
Answer:
The pollution caused by automobiles can be reduced by taking certain steps. First of all, the ingredients of fuel used in automobiles should be changed. Secondly, automobile engines should be redesigned and equipped with new devices like catalytic converters which can change pollutants into harmless substances. Yes, air pollution is a global problem. It is a problem for the whole world.
(ii) Given below is a table. Read the text and complete the table.
Answer:
F. Let’S Do Some Activities
1. Let’s think together :
The text you have read mentions some steps to reduce air pollution. Now work in groups to suggest more steps for dealing with the problem. You can refer to newspapers, and journals and discuss among yourselves to get more ideas (The teacher divides the class into four or five groups for the purpose)(This activity will be done in the class by the teacher.)
2. Let’s speak and listen :
Each group presents its ideas in class regarding the steps to control air pollution. Other groups listen and react to the ideas. After all the groups have presented ideas, commonly agreed aspects should be finalized. (The teacher acts as the observer and coordinator.) (This activity will be done in the class by the teacher.)
3. Let’s write :
Write a letter to the Editor of a newspaper / the Minister, Department of Environment explaining the importance of clean air and suggesting ways to keep it clean and pure. (ପରିଷ୍କାର ବାୟୁର ଗୁରୁତ୍ଵ ଏବଂ ଏହାକୁ ପରିଷ୍କାର ଓ ବିଶୁଦ୍ଧ ରଖିବାର ଉପାୟମାନ ବୁଝାଇ ସମ୍ବାଦପତ୍ରର ସମ୍ପାଦକ/ପରିବେଶ ବିଭାଗର ମନ୍ତ୍ରୀଙ୍କୁ ଏକ ପତ୍ର ଲେଖ ।)

Sub – Importance of clean air.
Dear Sir,
I shall be much obliged if you kindly publish this news item in your widely circulated newspaper.
Everybody needs pure and clean air in order to make his body fit. It is essential for the human body. Man can’t live even a moment without air. But it has become a dream now. Every comer of the world is filled with polluted air because of the growing industries of automobiles. When we respire the polluted air we suffer from many harmful diseases. The polluted air has caused a lot of harm not only to living creatures but also to trees and buildings.
All living creatures need pure and clean air so that they can keep themselves fit both physically and mentally. We all have to do something to keep it clean. A large number of trees should be planted every year to neutralize some pollutants. Some of the industries should be disestablished. The raw materials used in factories or the ingredients of fuel should be changed and equipment should be designed in such a way that can trap the pollutants before they escape into the atmosphere. Automobile engines should be equipped with devices that can change pollutants into harmless substances. Above all the government should pass laws to prevent and control air pollution.
Through your much-esteemed paper, I would like to draw the attention of the public as well as the government to do something to check air pollution and ensure a pure air.
Yours faithfully
Sasmita Praharaj
4. Let’s debate:
Some speak ‘for’ the motion and some ‘against’. The teacher acts as Chairperson.
(କେତେକ ପ୍ରସ୍ତାବ ସପକ୍ଷରେ ଓ କେତେକ ପ୍ରସ୍ତାବ ବିପକ୍ଷରେ କହିବେ, ଶିକ୍ଷକ ସଭାପତିଭାବେ କାର୍ଯ୍ୟ କରିବେ ।)
(i) Use of private vehicles should be banned to control air pollution.
(ବେସରକାରୀ ଯାନବାହନ ବ୍ୟବହାର ନିଷିଦ୍ଧ ହେବା ଉଚିତ ।)
Answer:
Group — A (For)
Undoubtedly the number of private vehicles used is more than the number of government vehicles. Their contribution to causing air pollution is more. It causes near about 60 per cent of air pollution. Some people misuse their vehicles. Even they take their vehicles to a very short distances. Some people use it as a luxury item. So private vehicles should be banned so that air pollution can be controlled.
Group – B (Against)
Only private vehicles can meet the demand of the exploding population. Though a number of passenger carriers and goods carriers are run by the government, they can’t meet the rising demand of the people. Government can’t provide adequate service transportation. Of course, vehicles are responsible for air pollution. But all private vehicles shouldn’t be banned. A lot of problems will arise if it is done.
(ii) Industries being the major source of pollution need to be disestablished
(ପ୍ରଦୂଷଣର ମୁଖ୍ୟ ଉତ୍ସ ହୋଇଥିବାରୁ ଶିଳ୍ପଗୁଡ଼ିକୁ ବିଲୋପ କରିବା ଆବଶ୍ୟକ ।)
Answer:
Group – A (For)
Most industries spew smoke, ash, dust and other pollutants into the atmospheric air. So the air gets polluted. It affects human beings, aquatic creatures, plants, trees as well as soil. Of course, industries fulfil the demand of the people. But they need to be disestablished to check pollution and save people and others from its ill effects.
Group – B (Against)
Modem society would come to halt without industries. Industrial products fulfil the demand of the people. Everything we use in our day-to-day life is a product of an industry or other. So the industries shouldn’t be disestablished.
G. Lets Enrich Our Vocabulary:
(i) There are some words/phrases in the text used to convey the harmful effects of air pollution on mankind.

From the above data it becomes apparent that the air of Choudwar has been polluted during those years due to an increase in the load of vehicular traffic (Table 2), a number of different industries (Table 1) and a number of pesticides users, lack of required green cover, cutting down a large number of trees, poor plantation drive and above all due to lack of required awareness among people regarding the cause and effects of air pollution.
As a result, disorders of the respiratory system, skin, eyes, blood etc. are on the rise in this area. The only satisfying development is the rise in the number of families using LPG as fuel for cooking. Though it is not possible to install the industrialisation, use of pesticides and number of vehicles used for transportation, the following remedial measures can be taken to reduce the degree of pollution as well as the extent of pollution-related health disorders.
- Industrialists should be cajoled to use smokeless fuels and develop green covers around the factories.
- Industries should be compelled to use precipitators, scrubbers and filters to check the production of particulate matter.
- Industries should be shifted to places far from human habitation.
- Owners of automobiles should use positive crankcase ventilation and catalytic converter to reduce emissions.
- The use of low-sulphur fuel should be made compulsory.
- Antipollution devices and alternate fuels should be used in automobiles.
- No big tree should be cut down further and steps should be taken for adequate – plantation.
- The public should be made aware of air pollution through electronic media, print media, shows, symposia etc.
Conclusion:
Hence a clear and transparent atmosphere is pleasant for leading a smooth life. The presence of smoke and dust in the air irritates the human mind. High population density and a large number of plying automobiles, industries etc. make the air highly polluted. This polluted air contains carbon monoxide, nitrogen, hydrocarbons, sulphur dioxide, dust, ashes, pesticide granules etc. which are detrimental to human health. Every citizen should come forward to wipe out the pollution so that we can make the world better.

Dispersal measures can be taken by raising the heights of smokestacks and collection measures can be taken by designing equipment to trap pollutants before they escape into the atmosphere.
Question 2.
What is acid rain and how does it cause damage in lakes and rivers?
Answer:
Acid rain is rain that contains oxides of sulphur and nitrogen along with other chemicals released into the atmosphere. It is very harmful to the environment. It makes water in rivers and lakes poisonous. The water turns acidic and affects aquatic animals and plants. It affects crops, trees, buildings, soils, drinking water as well as human beings.
Question 3.
What is the composition of air? When is air said to be polluted?
Answer:
Pure air doesn’t contain a single element. It is a mixture of several gases. It comprises 78 per cent nitrogen, 21 per cent oxygen, a little less than 01 per cent argon together with 0.03 per cent carbon dioxide. The air is pure and transparent as long as this composition is maintained. If the oxygen level gets reduced or irritating gases enter the atmosphere, the air is said to be polluted.
Question 4.
What are the basic approaches to control air pollution?
Answer:
There are three basic approaches to controlling air pollution. Preventive measures can be taken by changing the raw materials used in industry or the ingredients of fuel. Dispersal measures can be taken by raising the heights of smokestacks and collection measures can be taken by designing equipment to trap pollutants before they escape into the atmosphere.
Question 5.
What is acid rain and how does it cause damage to lakes and rivers? Or, What are the harmful effects of acid rain?
Answer:
Acid rain is rain that contains oxides of sulphur and nitrogen along with other chemicals released into the atmosphere. It is very harmful to the environment. It makes the water of the rivers and lakes poisonous. The water turns acidic and affects aquatic animals and plants. It affects crops, trees, buildings, soils, drinking water as well as human beings.
Question 6.
Where and when did the tragic Industrial accident take place? What were its consequences? Or, What accident took place at Bhopal in 1984? What were its tragic consequences?
Answer:
The most tragic industrial accident took place in Bhopal on 3 December 1984. A deadly gas from a chemical plant operated by Union Carbide escaped into the atmosphere. As a result of it, 4000 thousand local residents were killed and a large section of the city’s surviving population was rendered blind and crippling.
Question 7.
How is smoke produced? Where does it go?
Answer:
Various industries require steam. In order to produce the steam, they use fuels like coal, coke or furnace oil. These fuels are burnt in industries. During burning, along with heat, smoke is also produced. Of course, it disappears in a short time. But actually, it mingles with the atmospheric air and pollutes it.
Question 8.
How do thermal power stations cause more pollution?
Answer:
Some of the significant industries contributing to air pollution are cement, steel and ore-processing industries. But thermal power stations are rated the first among them as they discharge high amounts of smoke and ash into the atmospheric air. So they cause more pollution.
Question 9.
What are the effects of air pollution on vegetable crops and trees?
Answer:
Automobiles release maximum carbon monoxide into the atmosphere. As a result, the air is polluted. Particularly vegetable crops suffer ill effects from car exhaust gases. Many trees have been killed by the pollution from power plants.
Question 10.
How are buildings affected by polluted air?
Answer:
Polluted air not only affects human beings but also plants as well as buildings. Due to air pollution, fine buildings become shabby, and their walls blackened with soot that has settled on them. Building surfaces may actually deteriorate because of polluted air.
Question 11.
What harm can refrigerant do?
Answer:
Chlorofluorocarbons are a group of chemicals. They are gaseous compounds of chlorine, fluorine and carbon. These substances are used as refrigerants and cleaners. They can cause damage to the atmospheric layer. They may destroy the atmospheric layer (ozone layer) that protects us from harmful kinds of solar energy.
Question 12.
How is acid rain caused?
Answer:
Acid rain is caused due to the presence of sulphur oxide, nitrogen oxide and other chemicals in the atmosphere. It occurs when these gases react in the atmosphere with water, oxygen and other chemicals to form various acidic compounds.
Question 13.
Why do we still need to find out better ways to control air pollution?
Answer:
In spite of the formulation of laws and set of standards and norms, air pollution hasn’t been completely checked. So we still need to find out better ways to control it. Now physicians, engineers, botanists and meteorologists are carrying on research seeking new ways to check it.
Question 14.
What steps can be taken to reduce the air pollution caused by automobiles and factories?
Answer:
To reduce the air pollution caused by automobiles, the engines have been redesigned and new cars have been equipped with devices such as catalytic converters. They convert pollutants into harmless substances. Because of these new devices, air pollution from car exhaust has been reduced. Burning of low-sulphur coal and oil in factories has lowered pollution in many cities.
Question 15.
How do pollutants travel from one country to another?
Answer:
Now industrialised countries have taken steps to prevent and control air pollution. But one difficulty is that pollutants may be carried by the wind from one country to another. They often travel distances of thousand of miles. The death of lakes in eastern Canada has been caused by the acid rain that originated in the United States. Acids produced in Britain and France have caused damage in Sweden.
Question 16.
How is air more important for the man than food and water?
Answer:
A man can live without food for a month, and without water for two or three days. But he cannot live without breathing even for a minute. It is estimated that an average adult exchanges 15 kg of air a day, in comparison to about 1.5 kg of food consumed and 2.5 kg of water intake. So it is clear that air is more important for the man than food and water.
Question 17.
How do automobiles cause air pollution?
Answer:
The number of vehicles plying on the roads is increasing day by day to meet the demand of an exploding population of the world. Equally a greater number of lorries, and goods carriers are on the move. The use of cars, jeeps, and two-wheelers has increased dramatically along with heavy vehicles. Automobiles release Carbon Monoxide into the atmosphere. Thus they are responsible ’ for about 60 per cent of air pollution in various parts of the world.
Question 18.
How is air pollution responsible for increasing the temperature? Or, What is global warming and how is it caused?
Answer:
Global warming is the gradual increase in the earth’s temperature caused by high levels of Carbon Monoxide, Methane and Nitrous Oxide in the atmosphere. These gases tend to trap the radiation that reaches the earth from the sun. This process would eventually lead to global warming.
Question 19.
What health problems are caused by polluted air?
Answer:
The high cost of air pollution is most strikingly illustrated in its damaging effects on the human body. Polluted air causes eye irritations, scratchy throats and respiratory diseases. It also contributes to a number of serious diseases in the human body. The high levels of air pollution were linked to an increased number of deaths in Europe and the United States.
Question 20.
What are the industries that contribute to air pollution?
Answer:
Our air is being polluted with the by-products of industries. Of all the industries thermal power stations are rated the first, that discharge plenty of smoke and ash into the atmosphere. Besides cement, steel and ore processing industries also contribute to air pollution. Some of the chemical industries also release toxic fumes into the air along with the smoke.
Question 21.
Why does the oxygen level in the atmosphere get reduced?
Answer:
Various industries have been set up in modern times to meet the growing demand of the exploding population. They release irritating gases along with smoke into the atmosphere. These harmful irritating gases mingle in the atmosphere and pollute the air. So oxygen level in the atmosphere gets reduced and the air is said to be polluted causing respiratory disorders.
Question 22.
How have air quality programmes brought us benefits? Or, What are the air quality programmes made in different countries?
Answer:
The air quality programmes have brought improvements in several areas. Burning low-sulphur coal and oil in factories and power stations has reduced air pollution in many cities. The automobile engines have been redesigned and new cars are equipped with devices such as catalytic converters, which convert pollutants into harmless substances.
Question 23.
What are the basic approaches to control air pollution?
Answer:
There are three basic approaches to checking air pollution. They are preventive measures, dispersal measures and collection measures. Preventive measures involve changing the raw materials used in the industries or ingredients of fuel. Dispersal measures are raising the heights of smokestacks. Collection measure is designing equipment to trap pollutants before they escape into the atmosphere.

Para: A man can live without food for a month, and without water for two or three days, but he cannot live without breathing even for a minute. It is estimated that an average adult exchanges 15 kg of air a day, in comparison to about 1.5 kg of food consumed and 2.5 kg of water intake. It is obvious that the quantum of pollutants that enter our body through respiration would be manifold in comparison to those taken in through polluted water or contaminated food.

Para: In recent times, quite a large number of industries can be seen in urban areas as well as in rural pockets. Most of these industries spew dense smoke from their chimneys. What is this smoke made of and how is it produced? Industries require steam and to produce it various fuels such as coal, coke, and furnace oil are burnt. During burning, along with heat, smoke is produced. Where does this smoke go? Apparently, it disappears in a short time but in reality, it never does so. Instead, it mingles with the atmospheric air and pollutes it. We respire this polluted air containing obnoxious gases, ash and dust particles. Without our knowledge, our lungs slowly become garbage dumps for these pollutants.

Para: Automobile exhausts are in no way less dangerous than industrial smoke. It is reported that automobiles in Greater Kolkata alone spew about 1500 tonnes of pollutants into the atmosphere every day. It is stated that a person living in Kolkata, whether he is a smoker or not, is forced to inhale toxic substances equivalent to smoking two packets of cigarettes a day. The level of pollution in cities like Delhi, Mumbai and Chennai are equally alarming. To meet the demands of an exploding population, the number of buses plying on the roads are being increased. Equally a greater number of lorries and other goods carriers are on the move.
Along with heavy vehicles, the use of cars, jeeps and two-wheelers such as bikes, scooters and mopeds has increased dramatically – all contributing to significant levels of air pollution. Automobiles are responsible for 60 per cent of air pollution in various parts of the world as they release maximum carbon monoxide into the atmosphere. The menace of air pollution attributed to automobile exhausts has now reached the peak level and if this trend continues, we may have to wear nasal filters on our noses in future.

Para: The damage caused by pollution is enormous. In money alone, it represents a loss of billions of dollars each year. Many flower and vegetable crops suffer ill effects from car exhaust gases. Trees have been killed by pollution from power plants. Cattle have been poisoned by the fumes from smelters and recover aluminium from ore. Air pollution causes rubber tyres on automobiles to crack and become porous. Fine buildings become shabby, their walls blackened with soot that has settled on them. Building surfaces may actually deteriorate because of air pollution.
ଅନୁବାଦ : ପ୍ରଦୂଷଣଦ୍ୱାରା ହେଉଥିବା କ୍ଷତି ଅତି ବ୍ୟାପକ । କେବଳ ଟଙ୍କା ଆକାରରେ ପ୍ରତିବର୍ଷ ନିୟୁତ ନିୟୁତ ସଂଖ୍ୟକ ଡଲାର କ୍ଷତି ହେଉଛି । କାର ନିଃସୃତ ବାଷ୍ପଗୁଡ଼ିକର ଖରାପ ପ୍ରଭାବରେ ଅନେକ ଫୁଲ ଓ ପରିବା ଫସଲ କ୍ଷତିଗ୍ରସ୍ତ ହୁଏ । ବିଦ୍ୟୁତ୍ ଉତ୍ପାଦନ କେନ୍ଦ୍ରରୁ ଉତ୍ପନ୍ନ ପ୍ରଦୂଷଣଦ୍ୱାରା ଗଛଗୁଡ଼ିକ ମରି ଯାଉଛନ୍ତି । ଧାତୁ ଦ୍ରାବକଶାଳାରୁ ଓ ଧାତୁପିଣ୍ଡରୁ ଆଲୁମିନିୟମ୍ ପ୍ରସ୍ତୁତି ସମୟରେ ନିର୍ଗତ ବାଷ୍ପଦ୍ବାରା ଗୋରୁଗାଈଗୁଡ଼ିକ ବିଷକ୍ରିୟାଦ୍ୱାରା କ୍ଷତିଗ୍ରସ୍ତ ହେଉଛନ୍ତି । ବାୟୁ ପ୍ରଦୂଷଣ ମୋଟରଗାଡ଼ିର ରବର ଟାୟାରଗୁଡ଼ିକରେ ସଂକୀର୍ଣ୍ଣ ଫାଟ ସୃଷ୍ଟି କରେ ଓ ସେଗୁଡ଼ିକ ସଚ୍ଛିଦ୍ର ହୋଇଯାଏ । ସୁନ୍ଦର ସୁନ୍ଦର କୋଠାବାଡ଼ିଗୁଡ଼ିକ ଅପରିଷ୍କାର ହୋଇଯାଏ, ସେଗୁଡ଼ିକର କାନ୍ଥ ସେଥିରେ ବସିଯାଇଥବା ଅଳନ୍ଧୁଦ୍ବାରା କଳା ପଡ଼ିଯାଏ । ବାୟୁ ପ୍ରଦୂଷଣ ହେତୁ କୋଠା ଚଟାଣସବୁ ବାସ୍ତବରେ କ୍ଷତିଗ୍ରସ୍ତ ହୋଇପାରେ ।
Para: But the high cost of air pollution is most strikingly illustrated in its damaging effects on the human body. Air pollution causes eye irritations, scratchy throats, and respiratory illnesses. It also contributes to a number of serious diseases. In both the United States and Europe, periods of high levels of air pollution were linked to an increased number of deaths.
ଅନୁବାଦ : କିନ୍ତୁ ବାୟୁ ପ୍ରଦୂଷଣର ବଡ଼ କ୍ଷତିଭାବେ ମଣିଷ ଶରୀର ଉପରେ ପକାଉଥିବା ଖରାପ ପ୍ରଭାବକୁ ଅତି ବିସ୍ମୟକର ଭାବରେ ବର୍ଣ୍ଣନା କରାଯାଏ । ବାୟୁ ପ୍ରଦୂଷଣ ଚକ୍ଷୁ ପ୍ରଦାହ, ଗଳା କର୍କଶତା ଓ ଶ୍ଵାସକ୍ରିୟାଜନିତ ଅସୁସ୍ଥତା ସୃଷ୍ଟି କରାଇଥାଏ । ଏହା ମଧ୍ୟ ଅନେକ ପ୍ରକାରର ଗୁରୁତର ରୋଗ ସୃଷ୍ଟି କରାଏ । ଉଭୟ ସଂଯୁକ୍ତ ରାଷ୍ଟ୍ର ଏବଂ ଇଉରୋପରେ ଉଚ୍ଚ ସ୍ତରର ବାୟୁ ପ୍ରଦୂଷଣ ସମୟରେ ମୃତ୍ୟୁସଂଖ୍ୟା ମଧ୍ୟ ବୃଦ୍ଧି ପାଇଥିଲା ।
Para: Much direct harm is done by air pollution. Scientists are alarmed because the amounts of gases such as carbon dioxide, methane, and nitrous oxide in our atmosphere are increasing. These gases tend to trap the tradition that reaches the earth from the sun and as a consequence of which the atmosphere could become warmer. This process would eventually lead to global warming.
ଅନୁବାଦ : ବାୟୁ ପ୍ରଦୂଷଣଦ୍ୱାରା ବହୁ ପରିମାଣର ପ୍ରତ୍ୟକ୍ଷ କ୍ଷତି ଘଟୁଛି । ବୈଜ୍ଞାନିକମାନେ ସତର୍କ ହୋଇଯାଇଛନ୍ତି କାରଣ ଆମ ବାୟୁମଣ୍ଡଳରେ ଅଙ୍ଗାରକାମ୍ଳ, ମିଥେନ୍ ଏବଂ ନାଇଟ୍ରସ୍ ଅକ୍ସାଇଡ୍ ଭଳି ବାଷ୍ପଗୁଡ଼ିକର ପରିମାଣ ବୃଦ୍ଧି ପାଇବାରେ ଲାଗିଛି । ଏହି ବାଷ୍ପଗୁଡ଼ିକ ପୃଥିବୀରେ ପହଞ୍ଚିଥିବା ସୂର୍ଯ୍ୟଙ୍କ ବିକିରଣକୁ ଧରି ରଖେ ଏବଂ ଯାହାଫଳରେ କି ବାୟୁମଣ୍ଡଳ ଅଧିକ ଉତ୍ତପ୍ତ ହୋଇଯାଇପାରେ । ଏହି ପ୍ରକ୍ରିୟା ଶେଷ ପରିଣତି ବିଶ୍ବ ତାପନ ଅବସ୍ଥା ଆଡ଼କୁ ନେଇଯିବ ।
Para: Scientists have been concerned, too, about the widespread use of a substance that may destroy the atmospheric layer that protects us from harmful kinds of solar energy. This substance belongs to a group of chemicals and chlorofluorocarbons. It is used as a refrigerant and a cleaner and was once widely used in spray cans.
ଅନୁବାଦ : ବୈଜ୍ଞାନିକମାନେ ମଧ୍ୟ ଗୋଟିଏ ଉପାଦାନର ବ୍ୟାପକ ବ୍ୟବହାର ବିଷୟରେ ଚିନ୍ତା ପ୍ରକଟ କରିଛନ୍ତି ଯାହାକି କ୍ଷତିକାରକ ସୌରଶକ୍ତିଠାରୁ ଆମକୁ ସୁରକ୍ଷା ପ୍ରଦାନ କରୁଥିବା ବାୟୁମଣ୍ଡଳୀୟ ସ୍ତରରୁ ନଷ୍ଟ କରିଦେଇପାରେ । ଏହି ଉପାଦାନ ଏକ ରାସାୟନିକ ଶ୍ରେଣୀ ଓ କ୍ଲୋରୋଙ୍ଗ୍ ରୋକାର୍ବନର ଅନ୍ତର୍ଭୁକ୍ତ । ଏହା ଏକ ଥଣ୍ଡା କରିପାରୁଥିବା ଦ୍ରବ୍ୟ ଓ ସଫା କରିପାରୁଥିବା ଦ୍ରବ୍ୟ ଭଳି ବ୍ୟବହାର କରାଯାଏ ଏବଂ ସିଞ୍ଚନ ପାତ୍ରରେ ବ୍ୟାପକ ଭାବରେ ଏକଦା ଏହାକୁ ବ୍ୟବହାର କରାଯାଉଥିଲା ।
Para: Another concern is acid rain. This is rain or other precipitation that contains oxides of sulphur and nitrogen, along with other chemicals. Acid rain causes damage to lakes and rivers. It poisons the plants and animals that live in the water. It may also affect crops and other plants. Stone buildings and monuments and drinking water.
ଅନୁବାଦ : ଅନ୍ୟ ଏକ ଚିନ୍ତାଜନକ ବିଷୟ ହେଉଛି ଅମ୍ଳ ବୃଷ୍ଟି । ଏହା ଏକ ବୃଷ୍ଟିପାତ କିମ୍ବା ଅନ୍ୟ ଧରଣର ବୃଷ୍ଟି ଯେଉଁଥରେ ସଲଫର୍ ଅକ୍ସାଇଡ୍ ଓ ଯବକ୍ଷାରଜାନ ଅକ୍ସାଇଡ୍ ସହିତ ଅନ୍ୟାନ୍ୟ ରାସାୟନିକ ପଦାର୍ଥ ରହିଥାଏ । ଅମ୍ଳ ବୃଷ୍ଟି ହ୍ରଦ ତଥା ନଦୀଗୁଡ଼ିକର କ୍ଷତି ସାଧନ କରିଥାଏ । ଏହା ଜଳରେ ଥିବା ଉଭିଦ ଓ ଜୀବମାନଙ୍କୁ ବିଷକ୍ରିୟାଗ୍ରସ୍ତ କରାଏ । ଏହା ମଧ୍ଯ ଫସଲ ତଥା ଅନ୍ୟାନ୍ୟ ଉଦ୍ଭିଦ, ପ୍ରସ୍ତର ସୌଧ, ସ୍ମୃତିସୌଧ ଓ ପାନୀୟ ଜଳକୁ କ୍ଷତିଗ୍ରସ୍ତ କରାଏ ।
Para: Acid rain affects everything it falls on. The water in rivers and lakes turns acidic. For instance, in Sweden, 4000 lakes have been so severely affected that no fish has survived. It also changes the soil’s nutrient content. It washes or leaches away nutrients like potassium, calcium and magnesium from the upper layer that help trees grow. Acid rain kills large stretches of forests, leaving behind leafless skeletons of trees.
ଅନୁବାଦ : ଅମ୍ଳ ବୃଷ୍ଟି ପଡ଼ୁଥିବା ପ୍ରତ୍ୟେକ ଜିନିଷକୁ କ୍ଷତିଗ୍ରସ୍ତ କରାଏ । ନଦୀ ଓ ହ୍ରଦର ଜଳ ଅମ୍ଳୀୟ ହୋଇଯାଏ । ଉଦାହରଣସ୍ୱରୂପ, ସ୍ବିଡ଼େନରେ ୪୦୦୦ ହ୍ରଦ ଏତେ ପରିମାଣରେ ଗୁରୁତର କ୍ଷତିଗ୍ରସ୍ତ ହୋଇଛି ଯେ ସେଥିରେ କୌଣସି ମାଛ ବଞ୍ଚାହାନ୍ତି । ଏହା ମଧ୍ୟ ମୃତ୍ତିକାର ପୁଷ୍ଟିକର ଉପାଦାନକୁ ପରିବର୍ତ୍ତନ କରିଦିଏ । ଏହା ଉପର ସ୍ତରରେ ଥିବା ପୋଟାସିୟମ୍, କ୍ୟାଲସିୟମ୍, ମାଗ୍ନେସିୟମ୍ ଭଳି ପୁଷ୍ଟିକର ଉପାଦାନଗୁଡ଼ିକୁ ଧୋଇନିଏ ଯାହାକି ଉଭିଦ ଅଭିବୃଦ୍ଧିରେ ସହାୟକ ହୋଇଥାଏ । ଅମ୍ଳ ବୃଷ୍ଟି ବିସ୍ତୀର୍ଣ୍ଣ ଅଞ୍ଚଳର ଜଙ୍ଗଲକୁ ନଷ୍ଟ କରିଦିଏ, କେବଳ ପଛରେ ଛାଡ଼ିଯାଏ ପତ୍ରଶୂନ୍ୟ ବୃକ୍ଷସମୂହ ।
Para: When forests begin to die, the animals and birds in those forests follow. Among the growing list of species threatened by acid rain are the Pied Flycatcher and Apollo Butterfly in Sweden. The Dipper fish has vanished from the river of Central Wales, and the Brown Trout from Norwegian lakes. The list goes on.
ଅନୁବାଦ : ଜଙ୍ଗଲଗୁଡ଼ିକ ଶେଷ ହେବା ଆରମ୍ଭ କଲେ, ସେହି ଜଙ୍ଗଲଗୁଡ଼ିକର ପଶୁପକ୍ଷୀଙ୍କ ପାଳି ତା’ ପରେ ପରେ ପଡ଼େ । ଅମ୍ଳବୃଷ୍ଟିଦ୍ୱାରା ବିପଦରେ ପଡ଼ୁଥିବା ବିଭିନ୍ନ ପ୍ରଜାତିଙ୍କର ବର୍ଣିତ ତାଲିକାରେ ଅଛନ୍ତି ସ୍ବିଡ଼େନ୍ର ପାଏଡ୍ ଫ୍ଲାଇକ୍ୟାଚର ଓ ଆପୋଲୋ ବଟରଫ୍ଲାଏ । କେନ୍ଦ୍ରୀୟ ୱେଲ୍ସ୍ର ନଦୀରୁ ଡିପର୍ ମାଛଗୁଡ଼ିକ ଏବଂ ନରୱେ ହ୍ରଦଗୁଡ଼ିକରୁ ସାଲମନ୍ଜାତୀୟ ମାଛ ଅନ୍ତର୍ଦ୍ଧାନ ହୋଇଗଲେଣି । ଏହି ତାଲିକା ବଢ଼ି ବଢ଼ି ଚାଲିଛି ।
Para: What about our health? Acid rain irritates the sensitive tissues of our eyes and lungs, particularly in children. It can also cause skin lesions.
ଅନୁବାଦ : ଆମ ସ୍ୱାସ୍ଥ୍ୟ ବିଷୟରେ କ’ଣ କହିବା ? ଅମ୍ଳବୃଷ୍ଟି ଆମ ଆଖୁ ସମ୍ବେଦନଶୀଳ ଟିସୁ ଓ ଫୁସ୍ଫୁସ୍ ବିଶେଷକରି ଶିଶୁମାନଙ୍କ କ୍ଷେତ୍ରରେ ଅସ୍ବସ୍ଥ କରିପକାଏ । ଏହା ମଧ୍ୟ ଚର୍ମକ୍ଷତ ସୃଷ୍ଟି କରିପାରେ ।
Para: Living being apart, even buildings are not spared. In Poland, the beautiful old buildings of Karkow are slowly being destroyed by acidic smog. In Athens, a city which is highly polluted, acid rain is eating into the marble of its world-famous monuments. Experts say that more damage has been done in the past 25 years than in the previous 2000!
ଅନୁବାଦ : ଜୀବନ୍ତ ପ୍ରାଣୀମାନଙ୍କ ବ୍ୟତୀତ, ଏପରିକି କୋଠାଗୁଡ଼ିକ ବାଦ୍ ପଡ଼ନ୍ତି ନାହିଁ । ପୋଲାଣ୍ଡରେ ଅମ୍ଳଯୁକ୍ତ ଧୂମକୁହୁଡ଼ିଦ୍ୱାରା କ୍ରାକୋର ସୁନ୍ଦର ପୁରାତନ କୋଠାଗୁଡ଼ିକ ଧୀରେ ଧୀରେ ନଷ୍ଟ ହୋଇଯାଉଛି । ଅତ୍ୟ ପ୍ରଦୂଷିତ ଏଥେନ୍ସ ସହରରେ ଏହାର ପୃଥବୀପ୍ରସିଦ୍ଧ ସ୍ମୃତିସୌଧଗୁଡ଼ିକର ମାର୍ବଲ ପଥରକୁ ଅମ୍ଲବୃଷ୍ଟି ନଷ୍ଟ କରିବାରେ ଲାଗିଛି । ବିଶାରଦମାନେ କୁହନ୍ତି ଯେ ବିଗତ ୨୦୦୦ ବର୍ଷ ମଧ୍ୟରେ ହୋଇଥିବା କ୍ଷତିଠାରୁ ଗତ ୨୫ ବର୍ଷ ମଧ୍ୟରେ ଅଧୂକ କ୍ଷତି ଘଟିଛି ।
Para: There are three basic approaches to control air pollution – Preventive measures, such as changing the raw materials used in industry or the ingredients of fuel; dispersal measures such as raising the heights of smokestacks; and collection measures, such as designing equipment to trap pollutants before they escape into the atmosphere.
ଅନୁବାଦ : ବାୟୁ ପ୍ରଦୂଷଣକୁ ନିୟନ୍ତ୍ରଣ କରିବାକୁ ତିନୋଟି ପ୍ରମୁଖ ଉପାୟ ରହିଛି – ପ୍ରତିଷେଧମୂଳକ ପଦକ୍ଷେପ ଯଥା ଶିଳ୍ପରେ ବ୍ୟବହୃତ କଞ୍ଚାମାଲର ପରିବର୍ତ୍ତନ କିମ୍ବା ଜାଳେଣିର ଉପାଦାନଗୁଡ଼ିକର ପରିବର୍ତ୍ତନ କରିବା; ବିକ୍ଷେପଣ ପଦକ୍ଷେପ ଯଥା ଉଚ୍ଚ ଚିମିନିର ଉଚ୍ଚତା ବଢ଼ାଇବା ଏବଂ ସଂଗ୍ରହଣ ପଦକ୍ଷେପ ଯଥା ପ୍ରଦୂଷକଗୁଡ଼ିକୁ ବାୟୁମଣ୍ଡଳକୁ ଚାଲିଯିବା ପୂର୍ବରୁ ଧରି ରଖିବା ନିମନ୍ତେ ଯନ୍ତ୍ରପାତି ନିର୍ମାଣ କରିବା ।
Para: Nearly, all the highly industrialized countries of the world have some type of legislation to prevent and control air pollution. One difficulty is that pollutants may be carried by the wind from one country to another, often for distances of thousands of miles. The death of lakes in eastern Canada has been caused by acid rain that originated in the United States. Acids produced in Britain and France have caused damage in Sweden.
ଅନୁବାଦ : ପ୍ରାୟତଃ ସମସ୍ତ ଶିଳ୍ପସମୃଦ୍ଧ ରାଷ୍ଟ୍ରଗୁଡ଼ିକ ବାୟୁ ପ୍ରଦୂଷଣର ନିରାକରଣ ଓ ନିୟନ୍ତ୍ରଣ କରିବାକୁ କେତେକ ପ୍ରକାର ଆଇନ ପ୍ରଣୟନ କରିସାରିଛନ୍ତି । ଗୋଟିଏ ଅସୁବିଧା ହେଉଛି ବହୁତ ସମୟରେ ହଜାର ହଜାର ମାଇଲ ଅତିକ୍ରମ କରି ପ୍ରଦୂଷକଗୁଡ଼ିକ ଗୋଟିଏ ଦେଶରୁ ଅନ୍ୟ ଏକ ଦେଶକୁ ପବନଦ୍ଵାରା ପରିବାହିତ ହୋଇଯାଆନ୍ତି । ଯୁକ୍ତରାଷ୍ଟ୍ରରେ “ଉତ୍ପତ୍ତି ହୋଇଥିବା ଅମ୍ଲବୃଷ୍ଟିଦ୍ୱାରା ପୂର୍ବ କାନାଡ଼ାର ହ୍ରଦଗୁଡ଼ିକର କଂସ ସାଧନ ଘଟିଛି । ବ୍ରିଟେନ୍ ଓ ଫ୍ରାନ୍ସ୍ରେ ସୃଷ୍ଟି ହେଉଥିବା ଅମ୍ଳଗୁଡ଼ିକ ସ୍ବିଡ଼େରେ କ୍ଷତି ସାଧନ କରିଛି ।
Para: There have been many initiatives in different countries for making laws, and setting standards and norms to check air pollution and ensure quality air. Air quality programmes have brought improvements in many areas. For example, burning low-sulphur coal and oil in factories and power plants has lowered pollution in many cities. To meet standards, automobile engines have been re-designed and new cars have been equipped with devices such as the catalytic converter which changes pollutants into harmless substances. Because of these new devices, air pollution from car exhaust has also been reduced.

Para: It is not easy to bring about the new developments needed to control air pollution. Many – physicians, engineers, meteorologists, botanists, and others are involved in research seeking new ways. Vast sums of money will have to be spent in the future to clean the air and to keep it clean. Often pollution control means higher prices – to cover the cost of control devices in emission systems of new cars, for example. But to most people, the cost is justified. Perhaps the day will come when people everywhere can breathe pure air in cities where the sunlight is no longer blocked by an umbrella of pollution.
