Proposal takes aim at risk posed by ‘chemical cocktails’
Mixture allocation factor would weigh toxicity of chemicals as a whole
As the EU prepares revisions to its registration, evaluation, authorisation and restriction of chemicals (Reach) regulations, researchers are proposing a way of accounting for the growing number of ‘chemical cocktails’ found in the environment and human body.
Current requirements treat each chemical in the marketplace individually and producers must demonstrate safe use, which includes the concentrations in the environment. However, this does not reflect the realities of chemical exposure and risk.
