How are the LQM/CIEH Dose Response Roadmaps used?

For each substance, the Roadmap comprises comprehensive dose-response charts (for oral, dermal and inhalation pathways, as appropriate) indicate observed health effects in humans and animals reportedly associated with various doses (mg/kg body weight/day).

Site-specific estimates of exposure (mg/kg body weight/day), based on soil concentrations, can be plotted on the Roadmaps. Seeing the predicted exposure for the site on the Roadmaps provides a rapid and cost-effective basis for interpreting the potential harm associated with exposure to soils at that site. This can be used by informed users to help evaluate whether SPOSH exists.

In the absence of a quantitative definition of SPOSH, this tool helps local authorities and their advisors to determine whether SPOSH is likely to exist.
