OECD Mutual Acceptance of Data (MAD)

In 2014 IMOA achieved OECD Mutual Acceptance of Data (MAD) status for our molybdate effects dataset. This substantially enhances the global relevance of the scientific dataset on molybdate hazard conclusions, originally generated for compliance with EU REACH.

MAD status is a data quality endorsement, awarded by the OECD’s Cooperative Chemicals Assessment Program (COCAM).  ‘Cooperative’ because scientific representatives from OECD member state countries work together to assess the technical robustness of the data and conclusions.  Our dataset was reviewed by COCAM scientists from Australia, Canada, Japan, Netherlands, USA, UK and the COCAM Secretariat.

The core of the OECD dataset, named ‘Highly Soluble Molybdenum Salts’, is data about molybdate effects, generated from studies using sodium molybdate dihydrate (SoMo).  This was the test substance for the REACH research and the basis for read-across to other (less soluble) molybdate compounds.  Being the most readily soluble moly compound and therefore the worst-case test scenario it provides the most precautionary results, which are the most acceptable to regulatory authorities.

Our understanding is that Mutual Acceptance of Data status means the molybdate dataset is now the starting point for any environment/human health legislation developed/reviewed by the 34 OECD industrialized member countries around the world, hence the significant boost to its international relevance.  In fact it applies to nearly 40 countries because some, such as Brazil and India, are not OECD member countries but they do adhere to COCAM Mutual Acceptance of Data outcomes.  In 2014 China also indicated it is considering adherence to COCAM outcomes.  Other applications for this data include regulatory compliance, environmental quality standards, and mine development impact assessments. 

The dataset is publicly available to download from the OECD Existing Chemicals webpage, published under the auspices of United Nations.  The OECD download  is called a SIAP (SIDS Initial Assessment Profile), which is a 15-page overview document containing the key data and hazard conclusions of the molybdate effects dataset (phys-chem, human health and the environment). Please note that neither possession of, nor access to, a copy of this document and the robust study summaries contained herein in any way confers “permission to refer” to the document or constitutes “legitimate possession of” the document for purposes of registering under the EU REACH Regulation or similar legislation anywhere in the world.
