Critical Review of "Metals Environmental Risk Assessment Guidance for Metals" (MERAG)

image of Critical Review of

Risk assessment of metals may need specific guidance in how to handle natural background, essentiality, and long historical use of metals. It may also be necessary to take bio-availability into account. The aim of the present project was to critically review proposals on principles for risk assessment of metals (MERAG), developed by the metals industry, in co-operation with the UK Government during 2005-2006. The different MERAG proposals were reviewed by different Nordic consultancies, and their views are summarised in the report. The project was initiated and coordinated by the Nordic Risk Assessment Project (NORAP), which receives funding from the Nordic Chemicals group, a subgroup to the Nordic Council of Ministers. This review was considered urgent, in order to be prepared for a possible proposal to implement the MERAG principles within the Technical Guidance Document on Chemical Safety Assessment, which is developed for use under the REACH regulation.



Fact Sheet 4 - “Marine risk assessment” and chapter 4 of Background Document “Biodiversity and sensitivity of marine versus freshwater systems”

Marine risk assessment was included in the TGD in 2003 (EC, 2003). The TGD comprises guidance on exposure assessment, effects assessment and PBT assessment on elements specific to marine environments.
