Despite the increasing use of pesticides in tropical countries, research and legislative efforts have focused on their temperate counterparts. In the present publication, the literature on environmental risk assessment of pesticides in tropical terrestrial ecosystems is reviewed. Potential differences in pesticide risks between temperate and tropical regions are evaluated, and research needs for tropical regions […]
Few suitable and standardised test methods are currently available to test the effects of genetically modified plants (GMP) on non-target organisms. To fill this gap and improve ecotoxicological testing for GMP, we developed a new soil ecotoxicological test method using sciarid larvae as test organisms. Bradysia impatiens was identified as a candidate species. A functional […]
The United Nations’ sustainable development goals have been established to end poverty, protect the planet, and ensure prosperity for all. Delivery of the sustainable development goals requires a healthy and productive environment. An understanding of the impacts of chemicals on environmental health is essential for sustainable environmental quality. However, current research on and regulation of […]
A protocol for a reproduction test with the collembolan Folsomia candida was developed, starting exposure with eggs instead of juveniles as required by OECD test guideline 232. Accordingly, the exposure and, thus, the test duration was extended. The extended test starts with synchronisation of eggs in a thin soil layer on plaster of Paris, selection […]
The lack of standardised methods to study soil organisms prevents comparisons across datasets and hampers the development of new global and regional experiments and assessments. Standardised methods are also needed to evaluate the impact of anthropogenic stressors, such as chemicals, on soil organism communities in the regulatory context. The objective of this critical review is […]
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.
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.
