About the role

Job summary

The Radiation, Chemical, Climate and Environmental Hazards Directorate (RCCE) at the UK Health Security Agency provides evidence and advice to protect health from Radiation, Chemical and Environmental Hazards. The Toxicology Department provides Public Health advice to other parts of RCCE, the Department of Health and Social Care and other government departments and agencies, Local Authorities and other stakeholders including members of the public on the risks to health from environmental hazards (chemicals, particles and bioaerosols). The Toxicology Department undertakes research that underpins chemical regulation and policy development. All of the research underpins the UKHSA role in public health protection from environmental hazards.

The International Regulation Group within the Toxicology Department undertakes translational research activities using in silico, in vitro and in vivo models for chemical hazard assessment, and works to harmonise these tools in collaboration with international partners, particularly the Organisation for Economic Co-operation and Development’s (OECD) Test Guideline Programme and related bodies. The OECD Environment Health and Safety programme covers the safe use of chemicals, nanomaterials, pesticides, biocides, and products of modern biotechnology. It aims to protect health and the environment, while avoiding duplication of effort, ensuring that efficiencies are made and barriers to trade avoided.
