The LQM/CIEH Dose-Response Roadmaps (DRR) [Free]

A quick and simple to use tool to help local authorities decide the S of POSH under the new Part 2A of the Environmental Protection Act 1990 and the existing Part IIA in Scotland.

Under Part 2A, Local Authorities and their advisors must decide whether sites pose a "significant possibility of significant harm" (SPOSH) before it can be determined as statutory "Contaminated Land".

Despite revised Statutory Guidance in England and Wales, there is no simple definition of what is, or is not, SPOSH. Consequently, the contaminated land community has historically addressed this question using single, subjective and precautionary estimates of what a “minimal risk” dose may be.

However, this approach has little relevance to the wording in Part 2A and ignores the vast quantity of toxicological and epidemiological information that is available for most contaminants.

The LQM/CIEH Dose Response Roadmaps provide a scientific basis for determining if site specific exposure estimates are likely to result in significant harm and therefore simplify decision making under Part 2A across Britain.
