ECO6-CSL: Identifying Transgeneric Biotransformational Potential

When aquatic organisms are exposed to chemicals in the environment, some of these chemicals maybe universally metabolised, whilst others are either metabolised by specific species/taxa or are non-metabolisable and therefore may bioaccumulate. The objective of this work was to develop […]

D2.2-VITO: Generation and Application of a Model to Determine Intra- and Inter-individual Variation in Biomarkers

Biomarkers which reflect levels of pollutants in the human body offer a unique opportunity to investigate impact of environmental pollution on humans. Biomarker levels in the general population are influenced by genetic, physiological and external factors. Knowledge on which factors […]

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 […]

EMSG35-BASF: Enhanced OECD TG 407 – Development and Validation

Concerns that toxicological test guidelines may not optimally detect effects on the endocrine system have lead to proposals to enhance the current sub-acute rodent OECD Test Guideline No. 407 (OECD 1995). The efficacy of the modified enhanced (phase 2) protocol […]

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 […]

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 […]

EMSG13: Genetic Sex Determination of Fish – Aquatic Toxicity Project D

Conduct a literature review on present understanding of sex determination mechanisms in wildlife and the current use of markers of genetic sex for wildlife species selected for use in the testing and evaluation of effects of endocrine modulators. This knowledge […]

EMSG31: Aquatic Invertebrates Study – Aquatic Toxicity Project C

Evaluate the published information on the reproductive endocrinology of aquatic invertebrates with a view to evaluate their potential use in aquatic hazard identification of endocrine modulators.

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 […]

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 […]
