ECT’s certificate of Good Laboratory Practice (GLP), which comprises the categories 4 (‘Environmental toxicity studies on aquatic and terrestrial organisms’) and 5 (‘Studies on behaviour in water, soil and air; bioaccumulation’), has been renewed in July 2021. For further information on ECT’s experience as certified laboratory according to the OECD principles of Good Laboratory Practice […]
ECT’s GLP certificate, which comprises the categories 4 (Environmental toxicity studies on aquatic and terrestrial organisms) and 5 (Behaviour in water soil and air, bioaccumulation and metabolism), has been renewed in May 2018.
European legislation requires testing of parasiticides using, among others, dung beetles (OECD GD 122). Currently, Aphodius constans, a dweller species, has been approved as a test species for residues in dung. However, results of tests using A. constans may not be relevant for tunneler species.
For the activated sludge respiration inhibition test, the updated OECD test guideline 209 (22 July 2010) requires more replicates per treatment than the former guideline. To accomplish this new requirement and process the test within a reasonable timeframe, ECT recently established a multi-channel oxygen meter that allows simultaneous measurement and processing of respiration rates in […]
The aim of the project was the validation of a sediment bioaccumulation test with endobenthic oligochaetes by an international ring test. The test method was developed taking into account existing methods (UBA-reports 298 67 419 (1999) and 206 03 106/03 (1999)). A test protocol was prepared and used to run the test. A total of […]
The aim of the project was the validation of a sediment toxicity test with the benthic oligochaete Lumbriculus variegatus by an international ring test. The test method was developed taking into account existing methods. A test protocol was prepared and used to run the test. A total of 14 institutions (governmental agencies, universities, contract laboratories […]
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 aim of the project was the validation of a bioaccumulation test with terrestrial organisms (soil dwelling oligochaetes) by an international ring test. The test method was developed taking into account existing methods (UBA-reports 206 03 909 (1997) and 298 64 416 (2001)). A test protocol was prepared and used to run the test. A […]
The aim of the project was to standardise a test guideline with two dung fly species to be used for the environmental risk assessment of veterinary pharmaceuticals, in particular endo- and ectoparasiticides excreted in dung. The test is designed to estimate the developmental toxicity of a test substance to the dung dwelling life stages of […]
The objective of this project sponsored by the German Federal Environment Agency was the improvement of existing laboratory tests with dung beetles and dung flies. It was aimed at identifiying a second dung beetle species for standardised laboratory tests that should belong to the ecological group of ‘tunnelers’. However, it was not possible to establish […]
ECT Oekotoxikologie GmbH was founded as a privately owned, independent enterprise in 1993, and joined the SynTech Research Group in November 2021.
In compliance with Good Laboratory Practice (GLP), we perform standardised ecotoxicological tests in the laboratory as well as at semi-field and field level.
