Mr. Swayne: To ask the Secretary of State for Health, pursuant to his answer of 15 May 2002, Official Report, column 678W, on air pollutants, what plans he has to make and assess measurements of concentrations of aldehydes in the air in localised environments; and if he will make a statement. [61527] Mr. Meacher: I have been asked to reply. An assessment of ambient formaldehyde concentrations was carried out by the former Department of Environment, Transport and the Regions in January to March 2000 to help inform the deliberations of the Department of Health's Committee on the Medical Effects of Air Pollutants. Formaldehyde was assessed as a marker for aldehydes. Monitoring sites were located at Teddington, London Marylebone Road, Southampton, Rochester, an industrial site near Hull and a coal burning site near Rotherham. Short-term concentrations (measured over 4 to 7 days) at all locations were low in comparison with concentrations that have been shown to produce irritation (see Table). Thresholds for sensory irritation in the majority of subjects are reported as 0.6-1.2 milligrams per cubic metre for formaldehyde and the World Health Organisation guideline is 0.1 milligrams per cubic metre. The highest concentrations were observed at the traffic dominated site at London Marylebone Road and the industrial site at Hull. No indoor measurements were taken. My Department does not have plans for further measurements of aldehydes. _________________________________________________________________________________________________.

Mr. Swayne: To ask the Secretary of State for Transport, Local Government and the Regions what assessment his Department's Health Committee on the Medical Effects of Air Pollutants has made to aldehydes in the last five years; what conclusions have been drawn; and if he will make a statement. [56259] Yvette Cooper: I have been asked to reply. In December 2000, the Department's committee on the medical effects of air pollutants (COMEAP) published a statement on the effects on health of aldehydes in ambient air. The statement reflected the committee's conclusions of the evidence of the effects on health of aldehydes. A copy of the statement follows, and is also available on the Department's website at http://www.doh.gov.uk/ comeap/statementsreports/aldehydes.htm Committee on the medical effects of air pollutants statement on effects on health of aldehydes in ambient air Aldehydes found in ambient air include irritant compounds such as formaldehyde and acrolein. It is possible, though unlikely, that exposure to the concentrations of these compounds found commonly in ambient air in the UK could cause symptoms of irritation of the eyes or mucous membranes of the upper respiratory tract. Outdoor concentrations of formaldehyde are generally low in comparison with concentrations that have been shown to produce irritation. Concentrations indoors may, on occasion, be sufficient to cause irritation: this is due to the release of aldehydes from building materials and from house fittings. Though formaldehyde is a carcinogen in rats, the risks to humans associated with exposure to ambient concentrations, if any, will be extremely small. Occupational exposure to high concentrations of formaldehyde has been linked with the development of asthma and a hypersensitivity response to this compound. The evidence is not clear cut: much more convincing is the evidence regarding the response to glutaraldehyde, though the concentrations of this compound in ambient air are very low. It is highly unlikely that exposure to ambient levels of aldehydes would lead to allergic and respiratory problems. There is some evidence to suggest that exposure to formaldehyde indoors is associated with asthma symptoms in children. However, the overall evidence is not, however, completely clear cut and more research will be necessary before this issue can be finally resolved.
