## Summary

The Department for Environment, Food & Rural Affairs (DEFRA) has awarded a contract for providing toxicological advice on air pollutants through a competitive quotation process below the threshold. The project, titled "Toxicological advice on air pollutants [Review of published Environmental Assessment Levels for a number of Substances, based on updated toxicological information]," involves reviewing and revising Environmental Assessment Levels (EALs) and producing toxicology dossiers. Key dates include the contract start date on 20th December 2024 and completion by 6th April 2025. The total contract value is £50,000, and the services will be delivered within the United Kingdom under the classification "Services related to air pollution" (CPV code: 90731000).

This tender offers significant opportunities for businesses specialising in environmental consulting, especially those experienced in toxicology and pollutant impact assessments. Small and medium-sized enterprises (SMEs) and voluntary, community, and social enterprises (VCSEs) are encouraged to compete. The involvement of DEFRA and the collaboration with the UK Health Security Agency ensures high visibility and influence. Tara Consulting, an SME based in Hungerford, has been awarded this contract, demonstrating the project's suitability for smaller, specialised firms. This tender can help enhance the business profile, secure further contracts, and build expertise in a critical and increasingly regulated field.

## Notice

The main objective of this project is to continue the on-going review and revision of EALs by applying the EA 2012 methodology, updated as appropriate to reflect our consultations (see details below). It will include the production of individual dossiers on the toxicology of specific chemicals from the open and grey scientific literature (the dossiers for selenium and piperazine are provided as examples in Appendix D), which will be the basis for establishing updated EALs, short term and/or long-term depending on the data, for each compound. The proposed EALs will be submitted for agreement by the EA and UKHSA. In addition, the contractors may be required to provide expert advice on request, in the form of a briefing note, for selected toxicological issues such as a synthesis of in vitro and in vivo evidence on genotoxicity and mutagenicity. The work undertaken will be carried out under the direction of the EA's Chief Scientist's Group, who will also liaise with UKHSA. - Estimated timescale would be for the work to be completed by the end of the financial year.
