Guy's and St Thomas' are among ten hospitals in the most polluted areas of London which will be equipped with new air quality monitors to measure levels of toxic air and help protect patients and staff.
Hospital patients, including young children and the elderly, are most vulnerable to the harmful health effects of air pollution, especially those suffering with respiratory conditions.
A recent study found 60 per cent of hospitals and NHS facilities in inner London are located in areas that exceed the legal limit for air quality pollutants.
The Mayor's new hospital monitors will support the NHS by providing real-time air quality measurements that will allow health professionals to take appropriate action to protect patients and employees – for example, warning patients about high pollution episodes and advising which hospital entrances have the lowest levels of pollution.
The Mayor of London, Sadiq Khan said: "Vulnerable hospital patients are more susceptible to the harmful effects of our toxic air pollution health crisis that harms lung growth and is linked to asthma, cancer and dementia. I am working with London's leading hospitals to install air pollution monitors and help find new ways to reduce pollution and protect patients.
"I'm doing everything in my power to protect Londoners from polluted air including cleaning up our bus and taxi fleet, and establishing the largest air quality monitoring network of any major city. We are now counting down to the world's first 24-hour seven-day-a-week Ultra Low Emission Zone in the central London congestion charge zone, which will help clean our air and reduce NOx road transport emissions in central London, including around many hospitals, by 45 per cent."
