Bahrain is ranked first among the most air-polluted countries in the Middle East in the volume of small particulate matter (PM) in the air. This came in the World Air Quality Report issued by the IQAir AirVisual site.
The annual report found that Bahrain, 59.8 points, had the region’s highest exposure to its newly introduced PM 2.5 criteria, which measures tiny airborne pollutants smaller than 2.5 microns and located in different parts of the world.
Bangladesh, Pakistan, India, Afghanistan, and Bahrain occupied the top five centers of the world’s most polluted cities, followed by Mongolia (6), Kuwait (7), Nepal (8), UAE (9) and Nigeria (10).
Finland, Australia, Estonia, and Sweden topped the top five, Norway (6), New Zealand (7), Canada (8), the United States (9) and Portugal (10).
Because of the small size of "PM 2.5" it is able to penetrate the respiratory system, and then the rest of the body, which may cause a wide range of adverse effects in human health in the short and long term. The report noted that air pollution is the biggest environmental threat to health, contributing to the premature death of 7 million people annually in the world.
“Contaminated air is the fourth most important cause of premature death globally. Air pollution is weighing on the global economy at an annual cost of $ 225 billion,” stated the report
IQAir AirVisual noted that natural factors such as dust storms contribute to air pollution in the Middle East, but stressed that human activity in the region contributes significantly to air pollution, including emissions of oil refineries, power stations and fuel-powered transportation, High use of chemical compounds and burning of waste in open spaces.
The report explained that the Middle East includes cities and countries with the highest levels of "PM 2.5" in 2018, which exceeded in Kuwait and Manama and Dubai, the annual guidance of the World Health Organization more than 5 times.
