Abstract

Describes a framework for the collation of toxicological data to support the derivation of soil contaminant intakes that are protective of human health. It has been developed by DEFRA and the Environment Agency, based upon work by a number of contractors. This involves assessing the potential harm to human health from contaminants in soil and using this information for deriving health criteria. Tolerable daily intakes (TDIs) and minimal risk levels (termed “Index Doses”) are derived for threshold and non-threshold contaminants, respectively. The latter refers to chemicals for which a threshold for health effects cannot be assumed, such as genotoxic carcinogens and mutagens. TDIs and Index Doses are derived from expert judgement of all the relevant data on the toxicological properties of the chemical. Written for technical professionals who are familiar with the risks posed by land contamination to human health but who are not necessarily experts in toxicology.
