Examining the links between air quality, climate change and respiratory health in Qatar

Little information exists concerning (i) source contributions to airborne particulate pollution in Qatar, (ii) the potential impact that deteriorating air quality may have on the respiratory health of residents, and (iii) how climate change may affect respiratory health through its impact on air quality. Air quality in Qatar may be negatively affected by naturally occurring contributions including dust/sand originating from adjacent desert regions, microbial communities that may be associated with these particulates, and volatile organic compounds (VOCs) released by blooms of phytoplankton in coastal waters. Of increasing concern are anthropogenic contributions, including emissions from the rapidly growing number of vehicles, from ships travelling in the Persian Gulf, and from industrial and construction activities. We examine the relative importance of these contributions and discuss some of the expected impacts on respiratory health. We conclude by speculating on the impact that climate change may have on air quality and respiratory health around Qatar.
