A proposal was prepared for the post-authorisation monitoring of veterinary medicinal products, in particular parasiticides. Such a monitoring might especially be useful for parasiticides identified as PBT substances, i.e., substances that are toxic (T), persist in the environment (P) and bioaccumulate (B). Based on a literature search, issues are discussed that have to be considered […]
In many parts of Africa, pesticides are used indiscriminately. Yet, ecotoxicological data relevant for the protection of soil organisms have usually been obtained under temperate conditions. In order to assess the effects of three commonly used insecticides (deltamethrin, dimethoate, chlorpyrifos) on microarthropods in African soils, uncontaminated natural soils were collected from Nigeria and Tunisia. In […]
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design, (2) to perform a pilot earthworm field study following the improved test design, and (3) to prepare an OECD draft guidance document.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 […]
To verify the sensitivity of ecotoxicological tests, reference substances with known toxicity are regularly tested. Ideally, such substances lack speciﬁcity in their mode action, are bioavailable and readily attainable, and their chemical characterisation is cost-effective. Boric acid satisﬁes these criteria, but has – due to reproductive effects in humans – most recently been characterised as […]
Residues of veterinary pharmaceuticals enter the environment via application of manure onto agricultural land, where particularly antibiotics can cause phytotoxicity. Terrestrial plant tests according to OECD test guideline 208 are part of the environmental risk assessment of veterinary pharmaceuticals. However, this standard approach might not be appropriate for veterinary medicinal products forming non-extractable residues or transformation products in manure and manure-amended soil. To assess such products, a new test design including a more realistic exposure scenario via manure application is needed.

J. Römbke: The bait-lamina test – a newly standardised functional method in soil ecology
The aim of this project, which was supported by the German Environment Agency (UBA), was to standardise and validate a test guideline using soil predatory mites, a Hypoaspis reproduction test. Testing effects of plant protection products on predatory soil mites may be needed for the listing of an active substance in Annex I of EU […]
The aims of this project were the compilation and publication of the results of workshops with international dung fauna experts (Aveiro group) and the further improvement of existing laboratory tests with dung beetles and dung flies. Two publications were prepared: first, recommendations for the preparation, performance and assessment of field studies with dung organisms, and […]
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.
