The World Health Organization (WHO) released its 2014 report into global air pollution with some concerning, but interesting finds.
It is quite shocking to see that Qatar, United Arab Emirates and Bahrain have all made it to the top 10 of WHO's list. Who would have thought that Qatar is the second most polluted country in the world.
The database looked at the air pollution levels of 1600 cities across 19 countries by using a reading called PM2.5 and PM10. PM2.5 is considered the best indicator of assessing health impacts from air pollution and examines the concentration of fine particulate pollution of 2.5 micrometers or less in diameter (PM2.5).
Thes particles might be smoke, dirt, mould or pollen and their fine size poses the biggest risks to human health as they can be inhaled and accumulated in the respiratory system. WHO says there is no safe level of PM2.5.
Here are the 10 most polluted countries in the world.
Average PM2.5 pollution: 101 ug/m3
With a population of almost 180 million urban air pollution in Pakistan causes thousands of adult deaths each year.
A World Bank report found that outdoor air pollution alone causes more than 80,000 hospital admissions per year; nearly 8,000 cases of chronic bronchitis, and almost five million cases of lower respiratory cases in children under the age of five.
Average PM2.5 pollution: 92 ug/m3
With a population of 2 million people and growing, Qatar also faces increased pollution from its high rate of construction and busy air traffic making it the second most polluted country in the world.
Average PM2.5 pollution: 84 ug/m3
The Afghanistan government estimates that air pollution is responsible for 3000 deaths every year in the capital Kabul.
With a population of almost 30 million, Afghanistan suffers from traffic congestion, dust and the geographical limitations of a mountainous city.
The city’s swelling size has led to illegal homes powered by diesel generators or for those who can’t afford electricity, they burn tires and plastic bags for fuel.
Average PM2.5 pollution: 79 ug/m3
Home to nearly 155 million people, the air quality has fallen nearly 60 per cent in the last 10 years. In fact three Bangladeshi cities are in the top 25 cities with the poorest air quality.
Average PM2.5 pollution: 76 ug/m3
With a population of more than 76 million, four cities in Iran make the top 10 list of most polluted cities in the world. A combination of poor political decisions, substandard gasoline and traffic congestion means that its residents inhale a deadly mix of rubber particles, asbestos, sulfur dioxide, nitrogen oxide and carbon monoxide.
Average PM2.5 pollution: 74 ug/m3
The average resident of Cairo breathes in more than 20 times the acceptable level of air pollution every day according to WHO. The growing number of cars, factories and power plants, and the use of old heating methods such as burning coal and wood are considered to be the main man-made sources of air pollution.
Average PM2.5 pollution: 64 ug/m3
It’s population may only be 2.7 million but Mongolia’s long, cold winters that can drop to minus 40 degrees Celsius means that many Mongolians burn coal for cooking and heating creating a huge air pollution problem. Its capital Ulaanbaatar is one of the most polluted cities in the world.
8. United Arab Emirates
Average PM2.5 pollution: 61 ug/m3
It may be one of the richest regions in the world, but it has made its fortune from the oil and gas industries that are notoriously filthy. With a population of more than 9 million, Dubai launched an annual “car free day” in 2010 to try and tackle its problems with congestion and pollution.
Average PM2.5 pollution: 59 ug/m3
In the winter of 2013, air pollution in New Delhi was 60 times higher than the level considered safe according to India’s Center for Science and Environment (CSE) and it had the highest rate of air pollution in the world according to WHO.
Pollution from construction sites, industrial emissions, open fires, vehicle emissions and a staggering population of 1.2 billion put India at number nine on the list.
Average PM2.5 pollution: 57 ug/m3
Air pollution is not entirely relegated to the world’s developing nations. The high income country of Bahrain may only have a population of 1.3 million but it scraped in at number 10 on the list due to its high levels of pollution from energy production, dust, smoke and industrial emissions.
WHO has used instruments that were manufactured in the west and calibrated there to give the answers the organization very much wanted. A world organization should not be biased and myopic in its reports. There are many uncontrollable, natural factors that lead to pollution. Qatar is a desert and during a sandstorm, visibility is reduced to just a few meters. Possibly the WHO officials took their readings of pollution in Qatar during such a period when the country was enveloped by a sandstorm.
I don't even notice. It's more polluted in my home country.
i feel sad for Qatar...
i hope from 2 position of most polluted Qatar will improve its pollution rate.
Instead of pointing the finger and carrying out finically wasteful surveys maybe WHO could do something constructive like develop cheap and eco-friendly ways to construct stadiums. It's only temporary. I still love you Qatar.
