## Summary

The procurement contract titled "Exposure and Effects of Veterinary Medicines and Pesticides to Aquatic Wildlife in Protected Sites" was facilitated by Natural England, a central government public authority based in London. This tender focused on deploying methodologies for chemical exposure assessment and analysis, targeting protected aquatic species and environments in the UK. The process has reached the complete award stage, with contracts effective from 7th October 2025 to 13th March 2026. The procurement method was an open competition, below the threshold, with successful collaboration from ENVIRESEARCH LIMITED, a supplier specialising in research and consultancy services.

This tender offers significant opportunities for businesses within the environmental consultancy and research sectors. Companies capable of providing innovative sampling and analysis methodologies could find opportunities for growth through partnerships and contracts like these. Furthermore, organisations familiar with using eDNA sampling methodologies and able to deliver cost-effective chemical analyses for ecological assessments would be well-positioned to compete. The process was inclusive of SMEs, making it accessible for smaller entities seeking to expand by engaging in government-backed environmental initiatives.

## Notice

Passive quantitative sampling methodology will be employed to allow the full picture of chemical exposure to wildlife to be assessed. Chemical analysis would be selective to chemicals most relevant to remain cost effective. Based on the above analysis, evidence of exposure above the regulatory acceptable concentrations (RAC) for each substance can be used to assess the potential for adverse effects on aquatic species. Furthermore, the additive or synergistic adverse effects of chemical mixtures can be assessed. Use of eDNA sampling methodologies is now well established and validated. eDNA data can demonstrate the ecological status of freshwater ponds and wetlands. Amphibia and aquatic invertebrate eDNA data will be used to assess effects of chemical contaminants in the protected aquatic habitats surveyed. The evidence of effects from biomonitoring data collected and the risk assessment evidence may allow direct management practices to mitigate the adverse effects of these chemicals, either at source, in wastewater treatment works or at the protected site. This work is designed to feed directly into the effects of chemicals on D4/D5 indicator species conducted by DEFRA Pressures.
