The
2nd edition of
the LQM/CIEH
GAC publication was launched on the 13th July 2009
in Nottingham. The publication has been updated to reflect the
significant changes in human health risk assessment technical guidance
and policy since the release of the first edition. The 2nd edition
builds on the work of the 82 contaminated land practitioners from the
public and private sectors who, under the guidance of LQM, undertook
the initial research on the toxicological and physical-chemical input
parameters for 76 substances. At the workshop facilitated by LQM and
CIEH in Nottingham in January 2009 these delegates derived a series of
GAC for use in generic quantitative risk assessment.
The 2nd edition includes Generic Assessment Criteria for an extended range of 81 substances including:
For each substance, GAC have been derived for a range of generic land uses and Soil Organic Matter contents and all toxicological and physical-chemical data inputs used in the derivation of the GAC are presented and discussed in the publication

Since its publication, we have received a number of questions and comments from consultants and regulators relating to the 2nd Edition. Many of these have been valid technical queries. In order to make LQM's answers or position on these issues available to a wider audience we have prepared a Frequently Asked Questions (FAQ) document for the 2nd Edition, which we endeavour to update as new queries are submitted. The latest version is available for download below:

In 2006 the Chartered
Institute of Environmental Health (CIEH)
and Land Quality Management Ltd (LQM) published the 1st edition
entitled "Generic
Assessment Criteria for Human Health Risk Assessment".
The publication was based on the output form a two-day workshop at the
University of Nottingham. The 1st Edition contained
a set of transparent, scientifically based and policy compliant generic
assessment criteria that soon became widely adopted by regulators and
practitioners as authoritative values for use in GQRA. These
became
known as the LQM CIEH GAC
The 1st edition included Generic Assessment Criteria for 34 substances, including beryllium, copper, vanadium, zinc, total petroleum hydrocarbon fractions (aromatic and aliphatic), four polyaromatic hydrocarbons and nine chlorinated solvents. All GAC were derived using the then current CLEA UK (beta) model.
However, with the publication of revised guidance and an updated version of CLEA by the Environment Agency in 2008, the GAC derived in the 1st edition no longer comply with UK policy. Consequently, the 1st Edition is no longer available for purchase.
As with the 2nd Edition, a number of technical queries were received relating to the 1st Edition and these where used as the basis for an FAQ document. The final version of which is available below:
