Ozone pollution – increasing numbers of deaths worldwide

[16 November 2011 - 18h09]

According to the WHO (World Health Organisation), since 1970 climate change has been responsible for 140,000 additional deaths each year across the world. This makes a total, up to the present day, of roughly six million “climate-related” deaths! And, according to Swedish doctors, this is only the beginning.

The doctors looked into the future consequences of atmospheric pollution on the ozone level. This is an aggravating factor for asthma attacks and increases the risk of myocardial infarction. It is also associated with mortality peaks, notably in urban areas of North America.

The authors explain that “in future decades, ozone pollution will continue to impact on mortality and morbidity”. In Europe, the countries most affected by major changes will be Belgium, Spain, Portugal and France. According to their calculations, by 2050 Europe will experience an increase in mortality associated with climate change in the order of 10% to 14%.

To be spared the consequences of ozone pollution, it would seem that the best idea is to follow the example of certain species of migratory birds! And to move north. More specifically to “Nordic countries where the mortality associated with these changes should be less”.

As far as health is concerned, the consequences vary according to the level of exposure, the volume of air inhaled and the duration of exposure. Most susceptible are children, the elderly, asthma sufferers and people with respiratory insufficiency.
