This case study looks at the air quality being experienced on a daily basis in London by people working and travelling about london.
It looks at how a combination of a standalone CamCleaner City air purifier, effective air filtration and a well-sealed building envelope can deliver clean, healthy, Indoor Air Quality.
In general terms the main health hazard comes from exposure to traffic pollution. Fine combustion particles and gases in a toxic mix that can be inhaled by people and are classed as a Group1 (highest level) carcinogen by the World Health Organisation.
No: 1 Euston Square is close to Euston station which is good for business and transport links of all types. Unfortunately transport such as trains buses and taxis produce this air pollution.
There are other outside sources such as the much publicised recent southern UK air pollution incident involving desert dust and also volcanic events causing disruption to air transport because of airborne particles.
Clearly these fine particles can sometimes travel in concentrated plumes over long distances and stay airborne almost indefinitely.
This also applies to traffic air pollution particles and gases that can stay in the air and react producing chemical smog.
Local sourced city air pollution from traffic, in the City of London for example, is classed as PM2.5 combustion particulate and the accompanying gas Nitrogen dioxide NO2 pose the main health threat to people living and working in London unless they smoke.
These two pollutants go together and high PM2.5 concentrations in areas with traffic inevitably means high levels of NO2 and the Euston Road near the station is one of the most traffic laden and therefore polluted roads in London. It was decided to measure airborne particle levels in key locations such as in the office, in the associated corridor outside the office, and close to the main entrance of the office building.
The results show the particulate air pollution level was measured at in the range 0.3 to 0.5 microns dia. which is a particle size range that can easily make deep lung penetration and
cause health problems.
