New publication on chemical sensitivity of earthworms from field populations

The environmental risk of pesticides for nontarget soil macroorganisms has mainly been assessed using the compost earthworm Eisenia fetida. However, E. fetida does not occur in agroecosystems and it is generally less sensitive than other earthworm species. Thus, the extrapolation of its response to pesticides to other earthworm species may lead to uncertainties in the […]

Logo of the project ‘Risk Assessment Innovation for Low-Risk Pesticides’ (RATION)

New project started: RATION

Low-risk pesticides including biopesticides such as plant extracts, semiochemicals and microbial pesticides shall play a large role in substituting synthetic pesticides according to the Green Deal initiative of the European Union. Further low-risk solutions (phages, protists, microbial consortia, and double-stranded RNA pesticides) are expected to reach the market in the next years. There are ongoing efforts by the European Commission to establish specific risk assessment schemes for such low-risk pesticides…

New publication: Minimizing experimental testing on fish for legacy pharmaceuticals

Lead by Anja Coors, a team of partners in the IMI-funded project ‘Prioritisation and risk evaluation of medicines in the environment’ (PREMIER) developed and recently published a decision tree that shall help to minimize animal testing within PREMIER and beyond. The risk-driven decision tree uses a combination of experimental testing with non-vertebrates and a fish-specific […]

Report ‘Soil monitoring in Europe’ now published

A tremendous effort has been invested in soil monitoring in Europe, at country- as well as EU-level. However, there is so far no comprehensive and updated state of knowledge to identify healthy soils and those requiring protection. For the last few years, the European Topic Centre on Urban Land and Soil Systems (ETC/ULS) has followed […]

Report published on further development of screening tests for the evaluation of potential PBT substances

Different ready biodegradability tests (OECD 301 series and OECD 310) are currently used for evaluating if a substance is readily biodegradable and for identifying potentially persistent substances. Although the methods differ considerably, the test results are considered equivalent. In persistency assessments under REACH, enhanced ready biodegradability tests with an extended test duration (up to 60 […]

New test guideline: Organic matter decomposition in contaminated soil

The decomposition of organic matter is a key microbiological function in soil. A soil is healthy when organic matter decomposition and nutrient cycling are intact. Against this background, a laboratory-based method was developed for quantitative evaluation of microbial decomposition of organic matter in contaminated soil. This method is based on the quantification of the ability […]

Publication on validation of a method to determine transformation of chemicals in manure

Manure is widely used as a fertilizer and applied to agricultural land. It may contain highly active chemicals like veterinary medicinal products or biocides, which enter the environment by this pathway. This is recognized by several regulatory frameworks, however, a detailed method for examining the transformation of chemicals in manure was lacking. The present publication […]

Critical review and proposal for multigenerational testing in standard soil invertebrates

Standard laboratory tests to evaluate the effects of stressors (in most cases chemicals) on soil organisms offer a good compromise between feasibility and outcome, i.e. they should be reproducible and provide robust results. However, these tests may underestimate potential effects of prolonged exposures, particularly for persistent contaminants. In the last years, there was an increase […]
