EMSG23: Endocrine Modulating Effects in Fish Along the Elbe River and in Reference Areas. Assessment of Risks Related to the Habitat Conditions and the Natural Variability of Endocrine Functions
The aim of the study is to identify effects caused by endocrine modulation in fish and evaluate these with respect to dysfunction in sex differentiation, development of functional organs as well as fecundity. Another aspect is the determination of 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 […]
D2.1-MRCI: Background Incidence of Key Biomarkers of Chemical Exposure within the General Population
The science of biomarkers and measurement of exposures via biomarkers has progressed substantially in the past ten years, resulting in several occupational exposure limits being set on the basis of biomarker measurement, and the acceptance of biomarkers as measurement of […]
EMSG27: Environmental Effects on Uterine Tissues of Baltic Seals With Special Emphasis on Organochlorines and Uterine Leiomyomas
The study investigated whether leiomyomas in grey seals, collected during the period of decreased levels of organo-chlorines, were in a regressive phase; and whether the period of increased levels of organo-chlorines caused the leiomyomas to proliferate. In addition, in vitro […]
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.
C1.6: Possibilities and capabilities of 3D-body-scanning systems for the purpose of risk assessment.
The result of this study shows that a vast pool of data is available from the many kinds of measurement surveys that have been carried out using 3D body scanner technology. However, to evaluate the data or to derive the […]
EMSG28: Development, Validation and Application of in Vitro and in Vivo Test Systems for Non-Oestrogenic Endocrine Disrupting Chemicals in Wildlife
The project will provide information on effective in vitro (T-screen & Keratonisation Assay) and in vivo assays (metamorphosis, migration and prolonged FETAX-assay) for alterations of thyroid and retinoid dependent processes. It will bridge the gap between the in vitro and […]
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 […]
