Worldwide increase of air pollution
Date:8/1/2012

This press release is available in German.

Hot summer days cause in large cities very seldom great happiness among inhabitants. On those days the air is highly polluted with automobile and industrial emissions what makes breathing difficult and unhealthy. According to the latest calculations of Max Planck scientist Andrea Pozzer this scenario could become true for most of world population in 2050 if no counteractive measures are taken. Especially China, North India and the Middle East are expected to be affected by a drastic decrease in air quality.

In 2050, the air quality worldwide will be as bad as it already is nowadays in urban areas of Southeast Asia. This is the result of a simulation of the atmosphere done by scientists at the Max Planck Institute for Chemistry, the Institute of Atmospheric Physics and the Joint Research Centre of the European Commission. The chemical atmospheric model EMAC used by the researchers for their current study is the first to include all five major air pollutants known to negatively impact human health: nitrogen dioxide, sulphur dioxide, ozone, carbon monoxide and particulate matter smaller than 2.5 micrometres which are regarded as particularly harmful.

Air pollution is one of the major current health risks of humanity. At present, urban outdoor air pollution causes 1.3 million estimated deaths per year worldwide, according to the World Health Organisation. That number will increase in coming years. Therefor Andrea Pozzer and his colleagues studied the impact of man-made emissions on air quality in different regions of the earth. They show, what could happen if no further action is taken to reduce pollutants.

"Our study shows that further legislation to control and reduce man-made emissions is needed, in particular for eastern China and northern India, to avoid hot-spots of elevated air pollution," says Andrea Pozzer of the Max Planck Institute for Chemistry in Mainz, whose latest research findings are published in the current issue of 'Atmospheric Chemistry and Physics', a journal of the European Geosciences Union. According to the results of this study eastern China and northern India are the places that are struggling with the highest pollution levels.

East Asia will be exposed to high levels of pollutants, such as nitrogen dioxide, sulphur dioxide and fine particulate matter (PM2.5). Northern India and the Arabian Gulf region, on the other hand, will suffer a marked increase in ozone levels. This is primarily due to population density and the expected increase in industrial production and transport in these areas. Air pollution in Europe and North America would also increase, but due to the effect of mitigation policies that have been in place for over two decades now to a much lesser extent than in Asia.

Pozzer and his colleagues studied the impact of man-made emissions on air quality, assuming past emission trends continue and no additional climate change and air pollution reduction measures beyond what is in place since 2005 are implemented. While pessimistic, the global emissions trends indicate such continuation.

Subsequent to these results the researchers want to broaden the analyses. In the near future they want to calculate how many people would actually be affected by the harmful effects of deteriorating air quality.
