CNT-based nanoporous membranes for treatment of wastewater and process waters

CNT-based nanoporous membranes with high flux for energy-efficient treatment of wastewater and process waters from natural gas and crude oil processing industries

Carbon nanotubes (CNT) represent an important group in the class of carbon-based nanomaterials. Their physical characteristics make them highly suitable for use in filtration methods, and lab-scaled applications have been very promising. However, large-scale CNT-based nanoporous membranes for application in industrial processes are not yet available. The objective of the present project is the development […]

Adaptation of the current earthworm field study guideline

Adaptation of the current earthworm field study guideline 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design, (2) to perform a pilot earthworm field study following the improved test design, and (3) to prepare an OECD draft guidance document.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). However, 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 […]
