Alarming indoor CO2 levels
London’s alarming levels of pollution are always a big topic of conversation. However, though the city's outdoors gets plenty of flack in the news, new research has discover that indoor air pollution in London could be a much bigger concern. To get a understand the levels of air pollution better, Dyson asked four volunteers across London to conduct some studies. They asked them to measure dust particles – an important measure of pollution – as well as carbon dioxide (CO2) levels in the places they visit on a daily basis.
The highest carbon dioxide (CO2) reading, 2284ppm, was recorded inside a packed train at Baker Street Station, almost five times the threshold for normal CO2 levels.
Bromley recorded a worryingly high at-home reading of 1172pm – the highest at-home reading throughout the course of the study.
Exposure to high levels of indoor air pollution can lead to health problems including asthma, respiratory irritation, heart disease, cancer and sick building syndrome.
