For the treatment of groundwater contaminated with chlorinated hydrocarbons, nano-scaled zero-valent iron (nano Fe0) represents an efficient alternative to other treatments as e.g. pump & treat. Upon selection of a suitable treatment method for a given groundwater a risk-cost-benefit analysis is performed. This analysis does only rarely consider the potential risk of the remediation method […]
The persistence assessment under REACH relies on compartment‐specific degradation half‐lives derived from laboratory simulation studies with surface water, aquatic sediment or soil. Although these data are given priority, they are not available for most of the compounds. Therefore, according to the integrated assessment and testing strategy for persistence assessment, results from ready biodegradability tests are […]
The currently applied environmental risk assessment procedure for pesticides in the European Union (EU) is highly standardised. To assess effects on soil organisms at the lowest tier, just one test substrate is used, OECD artificial soil, a mixture of sand, kaolinite clay and Sphagnum peat. Moistened and adjusted to neutral pH, this substrate is used […]
Prior to releasing a genetically modified plant (GMP) into the environment and placing it on the market in the European Union, an environmental risk assessment has to be performed according to Directive 2001/18/EC. Based on the results of a previous project conducted from 2012 to 2016 (for more information, see the project description and the […]
The interaction of pollutants and pathogens may result in altered (often enhanced) effects of the chemical, the biotic stressor or both. While standardised detection methods for immunotoxic effects of chemicals exist with regard to human health, such test systems are lacking for invertebrate species and no guidance is available on how immunotoxic effects of a […]
The first aim of the project is to assess whether the existing OECD test guidelines for ready biodegradability of chemicals (OECD test guidelines 301 A–D and 310) can be harmonized. The gained insights will be discussed at an international expert workshop in 2019. Laboratory experiments will be performed for a set of selected test substances […]
Products used for plant protection or as biocides often contain more than one active substance together with numerous formulation additives. The environmental risk assessment for such commercial mixtures applies as default the concept of concentration addition. There is remaining regulatory concern, however, that underestimation of risks can occur if components in the mixture interact synergistically, […]
The aquatic environment is continually exposed to a complex mixture of chemicals, with effluents of wastewater treatment plants (WWTPs) as one key source. The aim of the present study was to investigate whether environmental risk assessments addressing individual substances are sufficiently protective for such mixtures. Based on a literature review of chemicals reported to occur […]
The ‘1st International Earthworm Congress’ (IEC 1) takes place in Shanghai (China) from 24 to 29 June 2018. Jörg Römbke is member of the scientific committee of this conference. In addition, ECT contributes with the following two presentations: […]
The SETAC Pellston Workshop ‘Simplifying environmental mixtures – an aquatic exposure-based approach via exposure scenarios’ addressed the need to improve mixture assessments by considering different exposure scenarios related to land use. Recently, a series of papers from this workshop was published in Environmental Toxicology and Chemistry, including the work ‘Use of prospective and retrospective risk assessment methods that simplify chemical mixtures associated with treated domestic wastewater discharges’, to which Anja Coors contributed.
ECT Oekotoxikologie GmbH is a privately owned enterprise that was founded in 1993.
In compliance with Good Laboratory Practice (GLP), we perform standardised ecotoxicological tests in the laboratory as well as at semi-field and field level.
