21DAY: Phase 3 of the validation of the OECD Fish Screening Assay

The eight studies in the attached report were conducted as part of OECD Test Guideline program to validate a standardized OECD protocol for a 21-day fish screening assay for the detection of endocrine active substances (i.e. estrogen, aromatase inhibitors, androgen). […]

B2.2-FoBiG: Provide Examples Where Risk Characterisations can be Conducted With the Existing and Possible Inadequate Data Sets

This project will evaluate the estimates used today by several organisations (e.g. U.S.-EPA, WHO, EU) to assess the human health risks of chemical exposure, which result in the derivation of human limit values such as acceptable daily intake, reference doses […]

B3.7-HSL: The Rapid Generation And Analysis of Physiologically-Based Pharmacokinetic Models (PBPK Model)

The widespread use and acceptance of PBPK modelling has been advocated for many years, as this technique offers a more scientific and quantitative approach to chemical risk assessment, as well as offering the opportunity of a marked reduction in the […]

EMSG24: Environmental Oestrogens and the Neuro-Endocrine Regulation of Reproduction of Fish

The aim of the study was to study neuro-endocrine regulation, particularly the brain-pituitary-gonad (BPG) axis, 3 freshwater fish species (catfish, trout and tilapia) exposed to 4-nonyl phenol (4-NP) or oestradiol (EE). The research also sought to establish an immortalised gonadotroph […]

EMSG7: Screening Test in Fish – Aquatic Toxicity Project A

An in vivo screening test for oestrogenicity was developed jointly by three laboratories by measuring vitellogenin in fathead minnows after up to 21 days exposure. This method will be further refined by determination of (anti-)androgens and aromatase inhibitors in the […]

EMSG34A: Validation of the OECD protocol for the surgical castrate rat (Hershberger) assay

The objective of this project was the evaluation and validation of the Hershberger assay as part of the official OECD validation of this test method. This test, developed under the EDTA programme, is designed to help detect chemicals interfering with […]

EMSG34B: Validation of the OECD Protocol for the Rat Uterotrophic assay

The objective of this project was the evaluation and validation of the uterotrophic assay as part of the official OECD validation of this test method. This uterotrophic bioassay is intended to identify the in vivo activity of compounds that are […]

EMSG33: Chemical Repository

OECD Test Guideline Validation: to provide a set of defined test chemicals for the OECD test methods development for endocrine active chemicals and to guarantee that test method validation under OECD leads to reliable results by always using the same […]
