The health effects of air pollution
Generally, if you are young and in a good state of health, moderate air pollution levels are unlikely to have any serious short-term effects.
However, elevated levels and / or long term exposure to air pollution can lead to more serious symptoms and conditions affecting human health.
This mainly affects the respiratory and inflammatory systems, but can also lead to more serious conditions such as heart disease and cancer.
People with lung or heart conditions may be more susceptible to the effects of air pollution.
