Prioritisation and monitoring of veterinary medicines of potential environmental concern.
This project built upon a previous study funded by the Environment Agency, which brought together data on the usage, routes of entry, and the fate and effects of veterinary medicines in use in the UK. The information was used to prioritise these veterinary medicines in use in the UK in terms of their potential to be released to the environment and their ecotoxicity. A list of priority compounds was developed for further consideration.
A pragmatic and scientifically sound risk-based ranking approach was developed and applied to each of the compounds on the priority list in order to gain a greater understanding of the risks they pose to the environment (soil, surface water and groundwater) relative to others on the list.
