The world is becoming a contaminated site. Agriculture and industrialization needed to support more than seven million people is the main reason for this contamination. Some countries have controls that mitigate environmental degradation, but many, perhaps most, have only few controls. And if any are cleaned in these filthy lands, it will be a slow process and very expensive takes place over a period of years, decades, or even longer.
According to a report on the air quality outside of the World Health Organization, nearly 90% of people living in cities around the world are exposed to dangerous levels of air pollution. The database examined levels of air pollution in 1600 cities in 91 countries. It is only 12% of people were living in cities that met the guide air quality levels of WHO. The outdoor air pollution killed 3.7 million people in 2012.
The main causes of pollution are uncontrolled emissions of vehicles, dust, industrial waste, garbage, brick kilns, cooking stoves, burning wood, coal and biomass. Almost all the worst offenders are either major producers of oil and gas, or emerging economies are growing rapidly.
These are the ten most polluted countries in the world.
10. Bahrain
Bahrain is considered the 10th most polluted country in the world, with an average contamination of PM2.5 of 57 ug/m3. Bahrain is one of the most populous countries in the world, as it has a total population of only about 1.3 million people and per capita GDP in the country is high, as it is $28,559 for making it 12 best country in the world by GDP. However, the country suffers from high levels of air pollution. Life expectancy in Bahrain is 76 for women and 73 for men. The main causes of air pollution in Bahrain include smoke, dust, industrial and energy production.
With a PM2.5 rate of 66 ug/m3, Hamad Town was 51st on the list of cities with high air pollution more.

Air pollution in India is caused by emissions from vehicles, industrial emissions, construction sites, etc.
India also has a particular problem because of its rapid urbanization. There are several respiratory problems resulting air pollution in Indian society. The country is taking steps, but not enough, compared to the growth that the country has. This pollution kills up to two million people a year.
8. United Arab Emirates
It is widely recognized as one of the richest countries in the world and is also highly ranked as the 8th most polluted country since the average PM2.5 pollution in it is 61 ug/m3. The Gharbia - Biya Zayed was ranked 52th in the list of cities with high air pollution, PM2.5 rate of 64 ug/m3.
The UAE has a total population of approximately 9.2 million inhabitants and its GDP per capita is high, as it is estimated at $30,984. Life expectancy in the country is 76.7 years, which is higher than other Arab countries. But UAE pays a high price for that wealth to have some of the worst air pollution in the world, especially in Dubai, the most populous city. Because of this massive use of gasoline powered vehicles, the air in the UAE is worse than in countries like China and India. Moreover, according to the Department of Energy US. In 2010, the UAE has one of the largest ecological footprints in the world, ie 19.8 tons of carbon per capita per year, a higher rate of the US.
7. Mongolia
Mongolia is ranked as the seventh most polluted in the world with an average contamination of PM2.5 of 64 ug/m3 country. This country can not be in an arid area at all and can have a very small population of only 2.7 million people.

The most polluted city of Darkhan is Mongolia with a PM2.5 rate of 80 ug/m3, which are at number 26 of the cities with the highest air pollution.
The number of premature deaths, cases of chronic bronchitis and respiratory-related hospital admissions are on a rapid rise. The government has been trying to mitigate the problems by introducing measures such as fuel-based cleaner coal and modern stoves to meet its pollution crisis.
6. Egypt
Egypt enters the sixth most polluted in the world as the average PM2.5 pollution in it is 74 ug/m3 country.

Major sources of pollution of Egypt are notorious factories pollute the air with lead, gas and cement dust. Besides that, the vehicle exhaust gases are a major problem in large cities like Cairo, which had about 2.1 million vehicles on the roads. Environmentalists Egypt also struggle to control pollution each fall when farmers burn rice straw and other crop residues. Pollution, known as "Black Cloud" occurs after harvest, and is responsible for over 40 percent of air pollution in Cairo during this period.

Iran is the fifth most polluted in the world by the average PM2.5 pollution country is 76 ug/m3. The country has a total population of about 77.17 million people, which is high and per capita GDP is also high, as it is $12,478. The average life expectancy in Iran is 74 years. The main reason behind the increasing air pollution in the country is the large amount of dangerous particles that can be found in the air, such as carbon monoxide, sulfur, asbestos dioxide and nitrogen oxide are inhaled by those who They are living in Iran. The most polluted city is Khorramabad Iran with an average of PM2.5 of 102 ug/m3. It ranked eighth in the list of cities with high air pollution over the world.
In February 2015, legislators, even went as far as possible, wear masks in a bout of solidarity in order to draw attention to pollution problems. In 2012, there were 4,500 people died prematurely in Tehran due to air pollution problems. These data come from the Iranian Ministry of Health.
4. Bangladesh
The average rate of PM2.5 in Bangladesh is 79 ug/m3, which makes the country will become the fourth most polluted country in the world.

Life expectancy in Bangladesh is estimated at 70 years for men and women. There are 3 cities in Bangladesh which are classified among the 25 cities with the worst air quality, and the most polluted city in Bangladesh Narayanganj with PM2.5 pollution level of 89 ug/m3. He entered at number 17. Gazipur was 87 ug/m3 and was ranked 21st. Dakha was the 13th with 86 ug/m3.
There are about 230 million cases of respiratory illness per year in Bangladesh. This country has ancient technology, weak environmental legislation and little desire to see that change, ousting 9.8 million tons of greenhouse gases each year.
Meanwhile, as clean drinking water is becoming scarce, groundwater is pumped to be a great source. Unfortunately, much of this water contains arsenic, which is killing people.
3. Afghanistan
Afghanistan ranks as the third most polluted in the world, with an average contamination of PM2.5 of 84 ug/m3 country.

The number of people who die each year in Kabul from air pollution is estimated by the government of Afghanistan to be 3000 people. The use of diesel generators and burning tires and plastic bags are a source to increase the level of air pollution.
A growing population has led to the construction of illegal housing and lack of access to electricity and fuel. Therefore, people burn anything available, including plastics and toxic waste.
2. Qatar
The average rate of PM2.5 in Qatar is 92 ug/m3, so that the country ranked as the second most polluted country in the world.

It is estimated that air pollution is 4 times higher than the average levels that are considered acceptable the World Health Organization.
Political instability, corruption and lack of government measures to curb carbon emissions also lead thick smoke over large cities like Karachi, Lahore and Islamabad. The vehicle exhaust are a major problem in Pakistan and carbon emissions must be managed in order to avoid further problems with its citizens and mitigate respiratory diseases are now affecting young children in the country.
