Chemical mixtures – have your say on draft approach

In an important step forward in its work on “chemical mixtures” EFSA has launched a public consultation on its draft guidance on harmonised methodologies for assessing combined exposure to multiple chemicals. A second related consultation concerns how EFSA proposes to address the genotoxicity of chemical mixtures.

People, animals and the environment can be exposed to multiple chemicals (“chemical mixtures”) from a variety of sources such as the environment, food and consumer products. Understanding how combined chemicals behave is complex and the number of potential combinations is wide.

The proposed guidance document and related statement provide a practical framework to help assess the combined toxicities of chemicals in different areas of scientific assessments relevant to EFSA, such as pesticides, contaminants and food additives. EFSA used feedback from a previous public consultation held in 2016 to define the scope of this proposed framework.

EFSA will hold a technical hearing on the genotoxicity assessment of chemical mixtures on 27 September in Brussels, Belgium. Registration opens shortly.
