A generic comparison of the airborne risks to human health from landfill and incinerator disposal of municipal solid waste

A comparison of the potential risks to human health from municipal solid waste (MSW) incineration and landfill on a generic basis is attempted. For this purpose a 'worst case' approach is adopted and a number of assumptions regarding the size and activities of each waste disposal method are made. The airborne pollutants measured for an incinerator are different from those for a landfill with or without gas collection. However, based on the available information it appears that as far as airborne pollution is concerned, landfill sites without gas collection pose a potentially higher generic risk to human health than MSW incinerators performing to Environmental Agency (UK) standards. This analysis cannot be used to replace specific evaluations for a particular incinerator or a landfill site because local conditions can have a very large impact on the magnitude of risks involved.
