摘要: The environment may be exposed to veterinary medicines administered livestock due the application of organic fertilisers land. For other groups substances that are applied agricultural land (e.g. pesticides), preferential flow in underdrained clay soils has been identified as an extremely important pathway by which pollution surface waters can occur. Three soil column leaching experiments have therefore carried out using a investigate fate range antibiotics from sulphonamide, tetracycline and macrolide groups. These studies complemented at field semi-field scales, well modelling being reported separate papers. Each study had different objective. first examined effect pig slurry on mobility loam soil. second experiment investigated changes water pH slurry. final quantified extent tillage prior reduce antibiotic residues found It was no impact oxytetracycline although affected significantly application. also shown pre-tillage substantially through macroporous soils.
