ECO3A-UTO: Evaluating Multi-Media Fate and Transport models on a Regional and Global Scale
Computer models are increasingly used to simulate the behaviour of chemicals in the environment. Based on data on a chemical's properties, release rates and environmental characteristics, these programmes - known as multimedia fate and transport models (MFTM) predict concentrations in […]

MISTRA: A New Strategy for the Risk Management of Chemicals: MISTRA and Persistence
To evaluate the persistency of the selected model compounds in the environmental matrices air, water, soil and sediment. Reaction mechanisms and degradation pathways of the model compounds are studied. A theoretical approach will be made to arrive at the conceptual […]

EEM1-ASTRA: Identification and Evaluation of Emission Databases in Europe
Estimating how much of a particular chemical is released to the environment is key to assessing likely levels of exposure and risk to humans and the environment. Such estimates are often based on very general information due to a lack […]

EEM4: Development of Tools for Probabilistic Uncertainty Analysis in Environmental Risk Assessment of Chemicals
The risk to wildlife or the environment posed by a given chemical depends on whether its environmental concentration is greater than set quality objectives (the risk quotient). Both environmental concentrations and quality objectives are calculated based on chance (probability), a […]

EMSG21: Endocrine Disruption in the Marine Environment (EDMAR)
The EDMAR programme is investigating whether there is evidence of changes in the reproductive health of marine life and if so, seeks to identify possible causes and potential impacts. Areas for research include: development of methods for the detection of […]

EMSG22: Endocrine Disruption in the Aquatic Environment; Laboratory Investigation of Endocrine-Active Chemicals
Laboratory studies are being conducted in which fish are exposed to defined concentrations of known chemicals. Natural steroids, synthetic steroids and xenoestrogens will be assessed. The choice of test chemicals will depend on field studies in the UK and Germany, […]

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 […]

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 […]

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 […]

EMSG36: Further Development and Scientific Evaluation of Appropriate Methods for Identification and Characterisation of Toxic Effects of Hormonally Active Substances on Reproduction in Birds as Part of Multi-Generation-Studies
The effects of so-called ”endocrine disruptors” (EDs), i.e. hormone-like acting substances of natural or anthropogenic origin or compounds disturbing the endocrine system by other mechanisms, on reproduction are subject to extensive discussion worldwide. For better identification of such effects, regulatory […]
