Nitrogen is an essential nutrient for all living beings. However, many compounds containing nitrogen are harmful for the environment. Plant species adapted to nutrient-poor conditions are displaced from forests and heathland. Emissions of nitrous oxide from over-fertilized fields exacerbate climate change. In many places, manure is responsible for nitrate concentrations in groundwater climbing above the limit values. Excessive levels of nitrogen dioxide in ambient air from transport sources present a risk to human health. This analysis shows that nitrogen pollution can be markedly reduced. Since agriculture accounts for around two-thirds of nitrogen emissions in Germany, efforts should focus on this sector. Veröffentlicht in Broschüren.
The spread of veterinary medicinal products (VMP) and biocides onto agriculturally used areas represents a very important path of entry into the environment for these product groups. For this reason, current guidance (e.g. „Guideline on determining the fate of veterinary medicinal products in manure“ (EMA/CVMP/ERA/430327/2009) (EMA, 2011) stipulates experimental studies on transformation of VMPs and biocides in manure. However, the documents only contain basic regulatory requirements, whereas an experimental test guideline is still missing, both on EU and OECD level. To allow for a consistent assessment of studies within the registration process, a harmonized internationally accepted and validated test method is needed. A draft test guideline was developed within a previous R&D-Project “Development of test guidance for transformation of veterinary pharmaceuticals and biocides in liquid manure” (FKZ 3710 67 422) (Hennecke et al., 2015). The experimental method was examined and revised by an intra-laboratory comparison as well as an international inter-laboratory comparison (pre-validation ring test). In the present project, an international ring test has been performed and evaluated testing a veterinary medicinal product (florfenicol) in pig manure and a biocide (imidacloprid) in cattle manure. Moreover, two international workshops were organized; one at the beginning in connection with proceeding project (FKZ 3710 67 422) and one at the end of the project to discuss and evaluate the ring test. Based on the experimental results of the ring test as well as discussions and conclusions of both workshops, a revised draft test guideline was prepared. Veröffentlicht in Texte | 78/2016.
