Insights Wales | Research needs in Natural Resources Wales | Thomaz Andrade | 30/07/25 13:30 – 14:30

Thomaz will present a number of areas where further research is needed.

This presentation will explore evidence gaps related to chemicals in water in Wales, with a focus on identifying partnership opportunities to address these challenges. We’ll begin with an overview of the current Water Framework Directive (WFD) chemical status and Natural Resources Wales’ (NRW) work on emerging contaminants. From there, we’ll delve into key evidence needs for further discussion, including:

The potential of effects-based monitoring.

About the Speaker

The role of PAHs and cypermethrin remobilization from bed sediments in current failures.

How passive samplers can support biota monitoring.

Approaches for assessing mixture effects from emerging contaminants.
