Adaptation of the current earthworm field study guideline

Adaptation of the current earthworm field study guideline in order to harmonise field testing and risk evaluation for earthworms

This project has three aims: (1) to compile and critically evaluate standardised earthworm field studies in order to optimise the current test design, (2) to perform a pilot earthworm field study following the improved test design, and (3) to prepare an OECD draft guidance document. After having discussed different design options within the OECD-GSIG expert […]

Development of an ecotoxicological assessment concept for contaminants based on their bioavailability in soils with different filter und buffer properties

Development of an ecotoxicological assessment concept for contaminants based on their bioavailability in soils with different filter und buffer properties

The German Federal Soil Protection Act defines precautionary values for seven metals/metalloids which, if exceeded, indicate that concern for a harmful soil change exists, taking geogenic or wide-spread, settlement-related pollutant concentrations into account. All precautionary values given in the German Soil Protection Ordinance are based on total concentrations (aqua regia extraction). Since total metal/metalloid concentrations […]

Development and standardisation of an ecotoxicological test method for the environmental risk assessment of genetically modified plants

Prior to releasing a genetically modified plant (GMP) into the environment and placing it on the market in the European Union (EU), an environmental risk assessment (ERA) according to EU Directive 2001/18/EC has to be performed. Current testing of the effects of GMPs on non-target organisms is mainly based on ecotoxicological test methods that were […]

GBIF Information System Soil Zoology. Coordination of national and international assessment for the organism groups Lumbricidae and Enchytraeidae (Edaphobase II)

In this joint research project, ECT is responsible for the improvement of existing and the development of new methodological standards regarding collection, storage and usage of data in the German central data base on soil biology, Edaphobase. Besides taxonomy and biogeography the functional role of soil organisms (e.g. via gathering traits of at least the […]

Transformation of veterinary pharmaceuticals and biocides in liquid manure

Veterinary medicinal products administered to animals are excreted with urine and faeces. For animals housed in stables, the resulting manure is collected and stored before being spread onto agricultural land. Disinfection products used to sanitize stables are also transferred into the manure. Therefore, the spreading of manure is an important pathway of introducing veterinary medicines, […]
