Technical Protocol. Transformation of biocides in liquid manures

Abstract

The Reference Manure Concept, already developed for laboratory tests on fate and behavior of veterinary medicinal products in liquid manures and manured soils, was successfully applied for biocides used for disinfection purposes and control of insects in animal houses. Since the representative and reproducible sampling of manures from high-volume tanks has been considered impossible, excrement samples of cattle and pigs individually kept at an experimental animal house were taken. These samples were thoroughly matrix characterized. Then, tap water was added to prepare reference manures of definite dry substance contents. Subsequently, the long-term transformation of the biocides imazalil and cyanamide applied as {sup 14}C-labeled radiotracers was investigated in these manure samples. On the basis of the transformation tests, test manures with 7-day aged biocide residues were prepared and applied in laboratory tests on transformation and sorption in manured soil. By means of this experimental approach, the impacts of aging processes during manure storage and of the manure matrix on the fate of biocides in soils can be assessed already under laboratory conditions. These laboratory tests have been directed as closely as possible to agricultural practice as well as to analytical practicability and quality assurance. Finally, the methodological aspects have been compiled  More>>
