Considering the available definitions of endocrine disrupting compounds (Weybridge, 1996 and WHO/IPCS, 2002) it is recommended to follow an appropriate experimental design, duration of exposure, and completeness of relevant endpoints (OECD, 2002). As expected human exposures to chemicals, pesticides, biocides, […]
The overall goal of this project is to characterize the potential in vitro and in vivo activities of plant-derived endocrine active compounds (EACs) versus synthetic substances and to evaluate potential combinatory effects of relevance to fish reproductive health. In particular, the […]
Many in vitro toxicogenomics initatives so far focus on the overlap between in vitro mechanistic responses and in vivo toxicity, but are primarily concerned with mechanistic studies and hazard identification. Purpose of this study is to extend this towards applications of […]
The primary aim of this project is to develop improved methods for assessing potential effects of contaminated sediments on aquatic microorganisms, plants and invertebrates within and across different taxonomic groups, to be applied in a regulatory context such as REACH. The objectives […]
Recent results of the analysis of Cramer classes for inhalation studies indicate that local effects of the respiratory tract and eyes dominate the very low NOEC values in Cramer class 1 and also to some extent in class 3 and […]
This project will provide a short overview on existing methods for estimating aggregate consumer exposure, i.e. exposure that adds up from consuming different household consumer products, and is built upon the work that is already funded by LRI in response to […]
The current method of assessing the (anti-)androgenic potential of a compound in vivo is through the use of the Hershberger assay. This involves first castrating adult male rats, allowing the sexual accessory tissues to regress and then exposing the rats […]
Growing concerns regarding the possibility that environmental contaminants could mimic estrogens and androgens and hence disrupt endocrine systems have led to the evaluation of test systems to detect such contaminants. One system, the weanling rat assay, has been suggested as […]
The objectives of these project are: - to gain a quantitative understanding of how chemical and environmental characteristics interact to control long-term time trends of POP/PBT-like substances in various environmental compartments. - to test the ability of current dynamic multimedia models to […]
The specific objectives of this project are to support incorporation of in vitro metabolism data into BCF prediction models and to extrapolate in vitro test results to whole body biotransformation rates (kmet) to be used to refine BCF model predictions. […]
