On 18th March, the daily mean outdoor particle air pollution (PM2.5) hit 346 mg/m3 , nearly 14 times the World Health Organisation guideline.
Five air filter combinations were tested by Camfil. Additional standalone air filter units within an office can reduce office-generated pollutants and emissions e.g. volatile organic compounds
Camfil has sponsored Clean Air in London’s campaign to build public understanding of indoor air quality since 2011.
Camfil’s international testing team analysed air pollution in London between 16 and 20 March 2015.
They monitored ambient, or outdoor, air pollution and indoor air quality in Montague Place in central London and tested one or two air filter combinations each day in the office’s air handling unit. Camfil’s report can be downloaded here: Camfil IAQ London report
Camfil’s monitoring coincided with the worst air pollution episode so far this year.
On Wednesday 18 March, Camfil recorded a daily mean for fine particles (PM2.5) in outdoor air of 346 micrograms per cubic metre (mg/m3) which is nearly 14 times the World Health Organisation (WHO) guideline. They also recorded between 300,000,000 and 400,000,000 particles per cubic metre with a diameter between 0.3 microns (mm) and 0.5 mm. Continue reading
In July, King’s College of London and the Greater London Authority (GLA) released two reports commenting on the negative health impacts of air pollution in London and the Mayor’s on-going efforts and progress to deal with the city’s air quality problems.
Nearly 9,500 deaths from long-term exposure to NO2 and PM2.5
For the first time in the world, King’s College London, commissioned by the Greater London Authority and Transport for London, has used emerging techniques to calculate the health impacts associated with nitrogen dioxide (NO2) in London. This new study shows that in 2010 there was the equivalent of up to 5,900 deaths across London associated with long-term exposure to NO2.
At the same time, deaths associated with long-term exposure to PM2.5 were recalculated from 4,300 (in 2008 based on 2006 concentrations) to 3,500 (in 2010). The PM2.5 and NO2 figures can be combined to create a total figure of up to 9,400 equivalent deaths in 2010*. Continue reading
The Health & Safety Executive (HSE) has appointed a new committee to provide independent expert knowledge and advice on workplace health.
The workplace health expert committee (WHEC) will be made up of nine members who will provide expert opinion on emerging issues and trends, new evidence relating to existing issues and, on the quality and relevance of the evidence base on workplace health issues.
Working under the leadership of an independent expert Chair, the WHEC will provide scientific and medical advice to HSE’s Chief Scientific Advisor and Director of Research Professor Andrew Curran and to HSE’s Board. Continue reading
