In-house analytical services

In-house analytical services under GLP are now available at ECT. Analytical verification of actual test concentrations is essential in ecotoxicity studies, and we are now prepared to provide this service in-house.

Successful renewal of ECT‘s certificate of Good Laboratory Practice (GLP)

In compliance with Good Laboratory Practice (GLP), ECT conducts a broad range of ecotoxicity tests with aquatic and terrestrial organisms, bioaccumulation and environmental fate studies. 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; […]

ECT organises a ring test with dung beetles

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.

Activated sludge test according to updated OECD guideline 209

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 […]

Validation of a sediment toxicity test with the endobenthic aquatic oligochaete Lumbriculus variegatus by an international ring test

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 […]
