The official launch of the CLEA model took place on 17 March 2002, covering:-

• CLR 7 Assessment of Risks to Human Health from Land Contamination. An overview of the Development of Soil Guideline Values and Related Research

• CLR8 Priority contaminants for the Assessment of Land

• CLR9 Contaminants in soil: Collation of Toxicological and Intake Values for Humans

• CLR10 The Contaminated Land Exposure Assessment Model.

• Soil Guideline Values: SGV1 Arsenic; SGV3 Cadmium; SGV4 Chromium; SVG5 Mercury; SGV7 Nickel, SGV9 Selenium; SGV10 Lead.

Much of the documentation (but not the model) can be downloaded from the web.

Publications CLR7-10, Tox reports and SGV reports are available to download from the DEFRA website.
CLEA webpages can be found at www.environment-agency.gov.uk by navigating to the Land Quality and then to the Contaminated Land section.
