Here's text of written reply to the "incinerator" Parliamentary Question by Paul Holmes MP (Hansard, 30 November 2009, Column 539W)
Incinerators: Health Hazards
Paul Holmes: To ask the Secretary of State for Health (1) what recent assessment his Department has made of the effect on public health of emissions from a functioning incinerator; 
(2) with reference to the answer to the hon. Member for Lewes of 17 September 2007, Official Report, column 2209W, on infant mortality: incineration, what recent assessment his Department has made of the correlation between the presence of a functioning incinerator and the incidence of infant mortality in that area. 
Ann Keen: The Department has made no recent assessments of the effect on public health of emissions from incinerators, or the effects on infant mortality.
The health protection agency (HPA) recently reviewed the latest research on the impact on health of emissions to air from modern municipal waste incinerators and published a statement in September 2009. It concluded that, while it is not possible to rule out adverse health effects completely, any potential damage from modern, well-run and regulated incinerators is likely to be so small that it would be undetectable. The advice is available on the agency's website at:
The HPA also advised that studies of public health around modern, well managed municipal waste incinerators are not recommended, since any possible health effects are likely to be small.
