Another European EU funded study confirms that previous WHO air pollution limits set for PM2.5 and related Nitrogen dioxode NO2 are too high and now need to be lowered for health reasons.
This latest study led by Dr Rob Beelen, from Utrecht University in the Netherlands estimates that for every increase of 5 micrograms per cubic metre in annual exposure to fine-particle air pollution PM2.5, the risk of dying from resulting exposure rises by 7%. PM2.5 stands for particulate matter 2.5 microns and below in size and is usually comprised almost entirely of toxic traffic emissions.
In large cities such as London the annual mean values for PM2.5 are typically in the range 15 to 25 micrograms per cubic metre and sometimes even more at busy road junctions. Simple arithmetic indicates increased risk of dying at 14% to 28% above a base level of 5 micrograms per cubic metre.
The world health organisation says there is no safe level of exposure to PM2.5 pollution. Exposure results in raised levels of heart and lung disease in the population.
The Kings College air quality website now has an interactive website that enables anybody living in London to enter their work or home post code and get a personal colour coded map to show annual levels of PM2.5 fine combustion particulates and associated gas phase pollution such as Nitrogen Dioxide. An example is shown below for the City area of London.

It is difficult to visualise the business case when talking about general statistics on air pollution and health. What business opportunities are related to better IAQ? This presentation takes a cost based approach. What do you know about the total cost of ownership of a typical office building? Beyond the public health impact of poor IAQ, how can businesses benefit from better indoor air quality?
