Short-term exposure to air pollution, such as ground-level ozone, can affect the respiratory system because the majority of the pollutants enter the body through a person's airways. Short-term exposure to air pollution may lead to respiratory infections and reduced lung function.

Explanation:

How air pollution is destroying our health

As the world gets hotter and more crowded, our engines continue to pump out dirty emissions, and half the world has no access to clean fuels or technologies (e.g. stoves, lamps), the very air we breathe is growing dangerously polluted: nine out of ten people now breathe polluted air, which kills 7 million people every year.

The health effects of air pollution are serious – one third of deaths from stroke, lung cancer and heart disease are due to air pollution. This is having an equivalent effect to that of smoking tobacco, and much higher than, say, the effects of eating too much salt.million lives a year worldwide by 2050 through reductions in air pollution alone. The economic benefits from tackling air pollution are significant: in the 15 countries that emit the most greenhouse gas emissions, the health impacts of air pollution are estimated to cost more than 4% of their GDP.

“The true cost of climate change is felt in our hospitals and in our lungs. The health burden of polluting energy sources is now so high, that moving to cleaner and more sustainable choices for energy supply, transport and food systems effectively pays for itself,” says Dr Maria Neira, WHO Director of Public Health, Environmental and Social Determinants of health.The lack of visible smog is no indication that the air is healthy. Across the world, both cities and villages are seeing toxic pollutants in the air exceed the average annual values recommended by WHO’s air quality guidelines. To help people better understand just how polluted the air is where they live, the WHO, UN Environment and the Climate and Clean Air Coalition’s Breathe Life campaign developed an online pollution meter.

This year, WHO and partners are convening the first Global Conference on Air Pollution and Health in Geneva on 29 October – 1 November to rally the world towards major commitments to fight this problem. The conference will raise awareness of this growing public health challenge and share information and tools on the health risks of air pollution and its interventions.
