To ask the Secretary of State for Environment, Food and Rural Affairs what research her Department has commissioned into air quality in the Heathrow area; and if she will publish the findings. 
§ Mr. Bradshaw
Defra has commissioned Cambridge Environmental Research Consultants Ltd to model air quality in the Heathrow area. The report is expected April 2004. The Department also assesses air quality at a national level and in the Greater London area and publishes the results on its air quality website, the Air Quality Archive. Both these levels of assessment include Heathrow.
National air quality monitoring data are available at www.airquality.co.uk. The latest published national air quality modelling report "UK air quality modelling for annual reporting 2001 on ambient air quality assessment under Council Directives 96/62/EC and 1999/30/EC" is available at www.airquality.co.uk/archive/reports; as too is the latest research report modelling London's air quality "Modelling air quality for London using ADMS-Urban".
