A Review of the Scientific Basis for Proposed EU Limit Values for Organic Chemicals in Sludge
This is the third study on the occurrence of organic chemicals in sludge, commissioned in response to proposed changes to the Sludge Directive (86/278/EEC) and the potential introduction of limits on organic chemicals in sludge applied to land.
An earlier study had highlighted polycyclic aromatic hydrocarbons (PAHs) as a potential compliance risk.
In this project, potential human and environmental health risks posed by PAHs have been assessed and for the majority of congeners negligible risks have been identified. Benzo(a)pyrene has been highlighted as a potential risk. However, based on an understanding of exposure mechanisms, the uncertainties in the derivation of toxicological impact levels and the strict controls that already exist in the UK, it is concluded that the presence of benzo(a)pyrene in sludge recylced to land poses a negligible risk to public health and that any future restrictions on the basis of public health cannot be justified.
