Long-term exposure to high levels of outdoor air pollution has been linked with poor health in many cities around the world.
Using information from the South London Stroke Register (SLSR), a team including researchers from King’s College London wanted to find out if people who had a stroke were affected by higher levels of outdoor air pollution. They looked at the health of 1800 people who had a stroke between 2005-2012.
The researchers found that those living in areas with lower levels of particulate matter live longer after a stroke. Particulate matter is a type of air pollutant made up of tiny bits of matter floating in the air from natural sources such as dust and pollen as well as man-made sources like soot, smoke and car exhausts.
SLSR researchers and air pollution scientists from King’s College London are doing more research to find out how particulate matter causes poor health effects in people.
