What effect do high pollution days have?
Short term health effects of air pollution
Short term health effects occur when weather conditions cause pollutant levels to build up above normal background conditions.
These weather patterns tend to cause air pollution episodes, and these can last for several days.
On days when air quality deteriorates more people are admitted to hospital for lung and heart problems
while increased numbers of people visit their GP and need to take more medicine.
Many people will not notice any ill effects, but those who are sensitive may feel the difference.
Those with existing breathing problems such as asthma or COPD can be severely affected.
