Urban Outdoor Air Pollution Causes An Estimated 1.3 Million Deaths Per Year Worldwide

English: A schematic of the global air pollution. The map was made by User:KVDP using the GIMP. It was based on the global air pollution map by the ESA (see http://www.esa.int/esaEO/SEM340NKPZD_index_0.html , http://esamultimedia.esa.int/images/EarthObservation/pollution_global_hires.jpg ) (Photo credit: Wikipedia)

From the 3 August 2012 article at Medical News Today

Most of the world’s population will be subject to degraded air quality in 2050 if man-made emissions continue as usual. In this ‘business-as-usual’ scenario, the average world citizen 40 years from now will experience similar air pollution to that of today’s average East Asian citizen. These conclusions are those of a study published in Atmospheric Chemistry and Physics, an Open Access journal of the European Geosciences Union (EGU).

Air pollution is a major health risk that may worsen with increasing industrial activity. At present, urban outdoor air pollution causes 1.3 million estimated deaths per year worldwide, according to the World Health Organisation [1].

“Strong actions and further effective legislation are essential to avoid the drastic deterioration of air quality, which can have severe effects on human health,” concludes the team of scientists, led by Andrea Pozzer of the Abdus Salam International Centre for Theoretical Physics in Italy (now at the Max Planck Institute of Chemistry in Germany), in the new paper.

The researchers 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. They point out that, while pessimistic, the global emissions trends indicate such continuation…

 

The analysis now published is the first to include all five major air pollutants know to negatively impact human health: PM2.5, nitrogen dioxide, sulphur dioxide, ozone, and carbon monoxide. The scientists considered pollutants released through human activity, as well as those occurring naturally such as desert dust, sea spray, or volcanic emissions.

Taking all pollutants into account, eastern China, northern India, the Middle East, and North Africa are projected to have the world’s poorest air quality in the future. In the latter locations this is due to a combination of natural desert dust and man-induced ozone. The effect of anthropogenic pollution emissions are predicted to be most harmful in East and South Asia, where air pollution is projected to triple compared to current levels.

  1. There is no doubt air pollution is a big problem for our world . Air pollution is a major health risk that may worsen with increasing industrial activity. At present, urban outdoor Air Pollution causes 1.3 million estimated deaths per year worldwide, according to the World Health Organisation.So why we waiting for the next victim by air pollution ,support to PALS.

  2. It’s really horrible situation because air pollution is a major health risk that may worsen with increasing industrial activity. At present, urban outdoor air pollution causes 1.3 million estimated deaths per year worldwide, according to the World Health Organisation. That’s the reasons we should work against Air Pollution causes. I think we should also support PALS because PALS is a group of environmentally conscious people who love pure air want to live in a cleaner.

  3. Pollution is really very bad for human health. weather it is out door air pollution or indoor air pollution. The smoke and dust particles in the air outside be the cause of breathing problem. Air pollution is the cause of many major diseases. Prevent this outdoor air pollution and be safe and stay healthy. PALS is community for pure air lovers works on the facts of air pollution that how to prevent our earth from this.
