Assessment and management of inputs of veterinary medicines from the farmyard - VM02501

The aim of this study is to assess the potential environmental exposure arising from releases of veterinary medicines to the farmyard. The project will involve a series of semi-field and field studies to investigate those chemical and environmental factors affecting the concentrations of veterinary medicine released to the environment in farmyard runoff waters and in irrigation waters. Based on the results of these studies, current exposure assessment models for pesticides will be adapted and evaluated for estimating exposure concentrations arising from releases from the farmyard. Observations from the field studies will be compared with previously reported monitoring results for veterinary medicines to determine the relative significance of releases of substances from the farmyard compared to other routes of exposure (e.g. application of slurry to land, excretion of substances by pasture animals). Where appropriate, potential risk management options will be proposed. The results from the study will enable DEFRA (VMD) and regulatory bodies in other Member States to more accurately assess the risks posed to aquatic and terrestrial organisms by veterinary medicinal products. The proposed research will underpin VMD’s mission to seek to protect the terrestrial and aquatic environments by ensuring that there are no unacceptable long-term or short-term harmful effects arising from the use of veterinary medicines. It has relevance to DEFRA’s principal objective ‘to develop appropriate methodologies to assess potential impacts on terrestrial and aquatic environments arising from the use of veterinary medicines’ and helps to meet the DEFRA Scientific Objective ‘to develop, demonstrate and improve the ability of current risk assessment models to accurately predict environmental effects’.
