Transformation of veterinary pharmaceuticals and biocides in liquid manure

Veterinary medicinal products administered to animals are excreted with urine and faeces. For animals housed in stables, the resulting manure is collected and stored before being spread onto agricultural land. Disinfection products used to sanitize stables are also transferred into the manure. Therefore, the spreading of manure is an important pathway of introducing veterinary medicines, […]

Lumbriculus test recommended by EFSA

The newly proposed EFSA guidance document on risk assessment for plant protection products for aquatic organisms1 recommends the Lumbriculus test (instead of the Chironomus test) specifically for pesticides with fungicidal activity. ECT coordinated the validation ring test for the Lumbriculus OECD test guideline […]

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 […]

Evaluation of a biotest battery for the ecotoxicological characterisation of waste: ring test with 60 laboratories from 15 countries

In contrast to other standardisation projects the aim of this project was to standardise a test battery, not a single test, to be used for the hazard assessment of wastes. The ecotoxicological characterization of waste is part of its assessment as hazardous or non-hazardous according to the European Waste List (EWL). For this classification 15 […]

Organisation and performance of an international ringtest for the validation of the enchytraeid reproduction test

An enchytraeid reproduction test ring test was performed in line with OECD requirements. Twenty-nine institutions (mainly universities and contract research laboratories) from 15 countries from Europe and North America participated in this ring test. The co-ordinating laboratory centrally distributed the test chemicals, guidance papers and test organisms to all participants. In addition, several training courses […]
