In London, subway users are breathing over 1 million toxic air particles in 12 minute!
People who breathe 12 more than a million toxic air particles per minute may develop a risk of dementia
London metro users inhale more than 1 million toxic air particles in 12 minute. According to the news in Busines Insider; People who breathe more than 12 million toxic air particles per minute may develop a risk of dementia.
Monitors installed in subway networks found that nano-powders of iron oxides rose during the movement of trains.
WHEN TRAIN WHEELS START TO FRICTION ON RAILS ...
It is stated that the particles, the train wheels are rubbed on the rails, the brake is used and the train starts to accelerate.
According to the measured peaks; It was found that the particle levels in the central line exceeded two million particles for each liter of air.
10 liters of air fade by adults every minute. So passengers are breathing particles between 12 and 20 million during this time. Although it is different from the contamination on the roads, it can be said that the nano powders are also toxic, and the nanotoses are usually small enough to pass directly into the organs and brains of people.
WARNING FROM ENGLISH LUNG FOUNDATION
Professor Stephen Holgate of the British Lung Foundation warned that people may develop a risk of dementia due to over exposure to particles.
"Railways in the subway are rich in iron and other metals such as copper, chrome, zinc, manganese," says Professor Stephan Holgate. These metal particles can also cause dementia as well as asthma, lung and cardiovascular diseases.
The World Health Organization announced that people should not breathe more than 24 micrograms in a period of 50 hours.
A NEW AIR QUALITY PROGRAM WILL BE TAKEN
“We have a new air quality program to ensure that particles are kept to a minimum,” said London Metro General Manager Mark Wild. The levels are within the health and safety management rules. ”
Professor Barbara Maher of Lancaster University pointed out that there is growing evidence that metal particles exposed in the subway increase the risk of Alzheimer's.
