(M/EH049) Environmental risk assessment of veterinary medicines in slurry (ERAVMIS): Sandy soil field trial preliminary data. Blackwell, Paul1, Kay, Paul1, Boxall, Alistair1, 1 ABSTRACT- Medicinal products, such as antibiotics, are extensively used for both human and veterinary health. There is much published literature on drug residues in animal products such as milk and meat. However, comparatively few data are available on the occurrence, fate and effects of drugs in the environment. ERAVMIS is an EU Framework V funded project which will provide data to aid in the development of risk assessment tools for Veterinary Medicines. As part of the project, a field scale trial is being carried out on a sandy soil, which is likely to represent a worst case scenario for movement of drugs to groundwater. This will provide data on the fate and behaviour of a number of veterinary medicines with a range of physiochemical properties which may be applied to the land via manure and slurry. Slurry has been applied to the field, spiked with estimated realistic concentrations of the compounds. Soil, soil water and overland flow water samples have subsequently been taken. Analytical methods have been developed for the analysis of these samples. The results will provide information on the movement of the compounds in the environment and will be used to validate and further develop current risk assessment approaches. Key words: veterinary medicines, slurry, environmental risk assessment, sandy soil |
