Inhalation of air is very important to us. this is so important to us that we breathe the air which is being contaminated. Air is called polluted or contaminated when harmful gases are exposed to it. The pure gas which was free of germs and chemicals gets polluted due these unwanted things. these unwanted things or chemicals come from the smoke of industries vesicles, burning of crops, household.
As due to growing population these pollution making things are increasing. Deadly gases are such as Nitrogen Oxides, Sulfur Dioxide, Ozone are exposed to air in Avery vast amount. These deadly gases get mix in the air within a few minutes. Even though we can not see it or ignore it but this polluted air is a slow poison to us and also to the innocent animals.
Industry and factory are the main cause behind the air pollution. A huge amount of coal and natural gases are burnt daily to produce heat in industries. Due to the burning of coal and natural gases deadly gases such as carbon dioxide, methane, nitrous oxide are produced. Industry and Electrical generating factories are responsible for contributing more than 50 percent of greenhouse gases into air.
Household air pollution is a another reason behind such kind of contaminated air. Around 3 million people cook using solid fuels including Wood, Crop wastes, Coal and Dung. These indoor air pollution include Asbestos, Biological pollutants, CO, Formaldehyde, lead, etc which are extremely bad for human health By consumption of these indoor gases around 3.8 million people die every year.
Vehicle emission is a another problem for air which growing day by day. Vehicle such as cars and motor bikes emit pollutants when petrol and diesel are burnt. These pollutants include deadly gases. Carbon Monoxide is widely produced when the fuel does not born completely. It is found that a typical passenger vehicle emits about 4.6 metric ton of carbon dioxide per year. Isn’t much for us to fell ill ?
Not only carbon dioxide the vehicle are also responsible for producing Nitrous oxide and Methane.
Other factors behind the air pollution are deforestation, smoking, farming and chemicals and crop burning.
Due to these reasons air pollution has reached on its top. Air pollution is now one of the greatest threat to mankind but yet we are ignoring it. Air pollution is responsible for 7 million deaths per year all over the world WHO data shows that 9 out of 10 people breath air containing high level of pollutants. Air pollution is attributed to 9% of death globally.
Air pollution still has not come to its end. Many countries are on race for leading Air pollution rate. These countries are ranked as ten most polluted countries in the world for their worst air condition.
Bangladesh has been being named as worlds most polluted country. Bangladesh air condition is very unhealthy having the average concentration of PM 2.5 of 79 ug/m3. Bangladesh is home to 166 million people . Due to this vast population deforestation, industrialization, amount of vehicle are growing day by day. Due to the increase of industrial emission, Vehicle emission have become great issues for the air condition of Bangladesh.
These are the 2 basic reasons behind this killing air pollution. This deadly emissions mostly concentrated in the cities of Bangladesh. Brick making kilns mainly in dry seasons is responsible for imputing dust particles in air. Dhaka, the capital of Bangladesh is one of the most polluted cities in the world having pollution index 93.37.According to a new study on global air pollution it was found that 123000 people died in Bangladesh for unhealthy air condition in 2017.
Pakistan has become the 2nd most polluted country in the world. The increase in pollution rate is now headache to the Govt. of Pakistan. Pakistan has a very unhealthy air condition having the average concentration of PM 2.5 of 101ug/m3.The main cause behind the air pollution in Pakistan is due to inefficient use of energy.
Another cause of air pollution in Pakistan is its growing population. As to the growing population their is a vast increase in the vehicle emissions. Unregulated industrial emission and the boning of garbage and plastic have contributed the most to air pollution in urban areas. Bahawalpur is the most polluted city of Pakistan having the pollution index 164.135000 people die in Pakistan due to the consumption of bad air in every year.
3rd most polluted country in the world is Mongolia. The pollution index of Mongolia is 92.03 and the average concentration of PM 2.5 is 64ug/m3.The indoor air pollution is mostly responsible for increasing rate of pollution in Mongolia. As Mongolia is very cold in winter the temperature averages below 0 from November to March. For these on bearable cold Mongolians need a lot energy for heating in addition to the energy also for cooking.
For these reason coal and other biomass such as Wood, crop etc are burnt in a massive amount, thus causing air pollution in Mongolia. Ulaanbaatar is ranked as most polluted city in Mongolia.46% of Mongolians population resits in Ulaanbatar. To reduce the amount of the air pollution the Govt. of Mongolia is going to introduce a coal burning ban in Ulaanbaatar.
Afghanistan is on 4th number on this list. Pollution index of Afghanistan is very high and the average concentration of PM 2.5 of 84 ug/m3. The air condition of Afghanistan is very contaminated and unhealthy to live. The atmosphere of this country gets highly polluted due to many small sources.
These small sources include burning of poor quality fuel, people burning trash, small scale smelting plant and also industrial brick kilns. A huge amount of pollutant also comes from many bakeries, restaurants, wedding hall and also from household cooking stoves.
Due to the increase of this small sources the pollution of Afghanistan has come this mounting level. Kabul the capital of Afghanistan’s considered as the most polluted city of Afghanistan. This pollution level of Afghanistan is so high and deadly that many people die due to respiratory disorder.
It is estimated that 27000 deaths are due to HAP (Hazardous Air Pollutant),11000 deaths due to outdoor air pollution,3000 deaths are due smoke every year in Afghanistan.
India is the worlds 5th most polluted country having the average concentration of PM 2.5 of 59 ug/m3. According to WHO report 21 out of the world’s 30 most contaminated and worst air quality cities are in India. Ghaziabad a city of India is the world’s most polluted city.
To control this massive pollution a law was implemented in 1981.But this law could not work properly to control air pollution. India’s air is becoming deadly due to burning of fossil fuel, industrial emission, deforestation, vehicle emissions.
The major causes of air pollution in India crop burning and Diwali fireworks. It has found that 51% of pollution is due to industrial pollution,27% of pollution is due to vehicles,17% of pollution is due to crop burning and 5% of pollution is due to Diwali fireworks in India.
Severe air pollution in Delhi has resulted an effect on Taj Mahal. Taj Mahal one of the 7 wonders of the world is well known for its marvelous pure white colour. Due to industrial air pollution and other activities in Delhi the colour of Taj Mahal has faded.
This happened as to the presence of excess carbon and dust particles in the atmosphere of Agra. Air pollution has become a very serious health issue in India. According to the states of India’s environment reports air pollution is responsible for 12.5% of all deaths in India.
