The level of fine particles in the air in Qatar is almost six times above the permissible limit, research has shown.
Figures released by the air quality monitoring station at Qatar University showed that air pollutants are at 296 micrograms per cubic meter, when the permitted level is 50 micrograms per cubic meter.
The presence of pollutants like silver oxide, ground-level ozone, carbon dioxide and nitrogen were lower than the permissible levels, however.
This was attributed to vast desert and insufficient rainfall. The arid Gulf state has received between just six and 62 millimeters of rainfall over the past three years.
Last year Qatar hosted the 18th United Nations Climate Change Conference (COP18), drawing criticism as the country holds the record of the world highest per capita CO2 emissions.
