ECT is currently establishing an in-house analytical laboratory that will become operational early 2023. We are seeking an experienced chemist to lead this new analytical department under GLP, with a starting date in fall/winter 2022. The main activities of the senior scientist in analytical chemistry are to develop and apply analytical methods (particularly HPLC-MS/MS) for […]
In persistence assessment, enhanced ready biodegradability tests (eRBT) are used to close the gap between screening tests and complex simulation tests. However, only few data from such tests are available, and neither guidance on the design and interpretation of eRBTs, nor suitable validity criteria have been established so far. In a practical testing programme, five […]
Organic matter decomposition is a key soil microbiological function. Intact organic matter decomposition and nutrient cycling indicate that a soil is healthy. In view of these facts, a laboratory-based method has been developed to quantitatively evaluate this process. The ability of soil micro-organisms to decompose filter paper (lignin cellulosic material) as a standard organic material […]
The SETAC Europe 32nd annual meeting will take place in Copenhagen (Denmark) as physical conference with virtual components from 15 to 19 May 2022. Anja Coors is supporting the conference as member of the Scientific Committee, and ECT Oekotoxikologie will be represented by four people at the meeting. In addition to several platform and poster […]
ECT contributed to a recently published global reconnaissance of pharmaceutical pollution in rivers. Reaching out to colleagues globally and engaging them in a world-wide sampling campaign, the team around John Wilkinson and Alistair Boxall from the University of York measured the concentrations of 61 pharmaceuticals in 258 rivers, representing 1,052 locations in 104 countries across […]
PRORISK is a European Training Network funded by the European Union’s Horizon 2020 research and innovation programme. It creates a platform for training early-stage researchers in the field of advanced environmental risk assessment. Environmental risk assessment procedures are nowadays changing, incorporating for instance mechanistic, ecological, and socio-economic information. Consequently, risk assessments are becoming more comprehensive. […]
According to Directive 2008/98/EG in connection with Decision 2000/532/EC (European List of Wastes, LoW), waste has to be classified as hazardous or non-hazardous. The LoW contains ‘absolute hazardous entries’ (wastes that are hazardous without further assessment), ‘absolute non-hazardous entries’ (wastes that are non-hazardous without further assessment) and ‘mirror entries’ (wastes that can be classified as […]
Sunscreens containing UV filter substances, such as octocrylene (OCR) and butyl-methoxydibenzoylmethane (BMDBM), have been increasingly used to protect human skin against UV radiation. Both substances have been detected in monitoring studies in the freshwater and marine environment, and there has been concern about potential effects on aquatic organisms. In the present work, the environmental fate […]
After completion of a technical proficiency study in 2020 with three reference compounds (see news), ECT has successfully conducted a first fish short-term reproduction assay according to OECD test guideline 229 under GLP in 2021. We welcome inquiries for further OECD 229 studies using our in-house bred fathead minnows (Pimephales promelas) in 2022. For further […]
