Pollution: Airborne Particles

Volume 713: debated on Tuesday 27 October 2009

Question

Asked by

To ask Her Majesty's Government what percentage of the population in each local authority in Greater London is estimated to have been living in an area that (a) breached one or more European Union limit values for particulate matter (PM10) in 2008, and (b) is expected to breach one or more European Union limit values for nitrogen dioxide (NO2) in 2010. [HL5688]

Data commissioned by the Greater London Authority are available for 2006 and 2010, and are provided in the form of number of people exposed to 1) Concentrations of NO2 above 40 microgrammes/m3 in 2010—based on three different modelled met years, 2) Concentrations of NO2 above 60 microgrammes/m3 (as an approximation for an exceedence of hourly limit value) in 2010 based on 3 different met years and 3) Concentrations of PM10 above 40 microgrammes/m3 in 2006 and 2010 based on 2003 met year.1

Table 5 Population exposure (number of people) for NO2 (>40 microgrammes/m-3) for the year 2010 for different met years (2003, 2004 and 2006)

Information regarding the exposure of London's population to air pollution is also contained within the technical annexes of the Mayor's draft air quality strategy.

http://www.london/gov.uk/mayor/environment/air_quality/docs/AQS09-technical-annex.pdf.

Asked by

To ask Her Majesty's Government what harmful air pollutants are likely to be present in ambient air when concentrations of nitrogen dioxide (NO2) are high; and in what proportions. [HL5689]

Nitrogen dioxide (NO2) arises directly and indirectly from combustion processes. Concentrations are generally highest close to their emission sources, primarily road transport followed by the power generation industry and other industrial and commercial sector sources.

The nature of the combustion process and fuel used will determine the presence of other pollutants, such as particulate matter, polycyclic aromatic hydrocarbons, benzene, carbon monoxide and sulphur dioxide. It is not possible to define the proportions that these pollutants may be present in at any particular location at any one time. Proportions will vary with time, the distance from sources, meteorology, and chemistry depending on the type of combustion process and emissions released.
